TECHNICAL FIELD The invention relates to a welding device cooperating with a movement member and comprising an inner tube and an outer tube, the inner tube having a first free spirit projecting from and axially displaceable from a first member of the outer member of the outer member. second spirit, with which the welding means, the inner tube and the outer tube can be welded in different axial layers relative to each other, wherein the welding means comprises an axially directed thread and a tubular welding sleeve slit with at least one axially directed groove, which groove comprises At least one wedge-shaped recess with wedge surfaces, said locking means further comprises at least one wedge comprising wedge surfaces, which wedge surfaces, under the influence of a moving member comprising a gangway *, are movable along and relatively cooperating wedge surfaces of said welding sleeve, by means of which the moving welding sleeve is pressed against the outer tube and the inner tube. v where the movement means takes place by rotating the movement member about an axis substantially parallel to the longitudinal axis of the inner tube, the pair of aisles cooperating with said thread, where the rotation of the movement means takes place via a pivot rod when the pivot rod is rotated relative to the inner axis around a long axis.
PRIOR ART IN WO2009 / 102260, the edge is a welding device for telescopic devices with an inner ridge and an outer tube as described above. This welding device has a number of advantages. It has a reliable and easy-to-maneuver welding function due to the fact that the welding concept with a tangentially acting kit on a welding sleeve offers the self-welding properties in one direction without giving rise to self-welding in the control wedge. Darrned produces a very strong load which at the same time can be regulated with insignificant forces. The welding means is arranged on the other of the inner tube which is inserted into the outer tube. The adjustment takes place with a control member on the free spirit of the outer tube via a pivot rod which is axially displaceable relative to the welding member. Delia is a simple construction that can be manufactured at low cost. The disadvantage is that the said welding device is not self-lasing in both directions. It is normal to want self-welding against compression of the telescopic device. But in some applications it can be Onskvart aft to have self-welding in both directions. Delia is the case with e.g. batshakar when you want to be able to apply a pulling force on an object. Another application is walking and skiing poles where the inner tube can be pushed out of the outer tube under the influence of a spring element. In that case, the inner tube is subjected to a projecting force when the laser member is in load position and the fourth of the laser member is self-lasering in both directions. Delia can be achieved by combining said welding device with prior art according to WO2005 / 085659 where a welding concept with two axially opposite tangentially acting wedges is described. The last-mentioned document describes how the welding means is brought between the load and the tip layer through which these wedges are displaced axially relative to each other. This is done by a spring-loaded push rod that spontaneously presses the wedges in the direction of each other. By a force in the axial direction, the spring force can be overcome and the locking member brought to the Open position. Due to this operating principle, the welding means can not be arranged on the spirit of the inner tube because said push rod cannot be displaced axially relative to the welding means. In the technique according to WO2009 / 102260, the welding means is operated by rotating a moving member with a thread by means of the pivot rod which is axially displaceable relative to the moving member. During this rotation, the movement means presses the tangentially acting wedge against the sleeve, whereby it expands with a lasing effect as follows. If one wishes to operate two axially opposite wedges with the same principle, the problem arises that a twice as rank axial displacement of the moving member is required. This meant twice as large an angular displacement while maintaining the same gait. In other words, the actuator must be rotated twice as large an angle, which means that the locking member becomes much more cumbersome to actuate. The optimum is that the maneuvering takes place with a compressive force which is achieved by the user pressing the thumb against the actuator on a control device arranged on the free spirit of the outer tent. The said document provides, without any more detailed description, that this can be achieved by means of a screw screw which is actuated by a nut, which nut is pressed in the axial direction. The problem with this is that a moving screw needs to have a large pitch due to the friction that counteracts the movement. But the larger the slope, the smaller the angular displacement. Della can not be compensated with a longer axial displacement of the operating member because the user's thumb can normally not be displaced more than about 20 mm relative to the handle. A smaller angular displacement can also not be compensated with a larger increase in the gait of the moving member, since it can then be stepped up under the influence of a pull-out force on the inner tube. Another problem that prior art does not present with the Wagon solution is how to avoid blocking the movement's regulation in cases where one wishes to extend the inner tube with the aid of a spring element. Another disadvantage of the prior art is that the rotating arrangement is provided with a rotation by means of a nut, the responsibility being to achieve a bearing of the moving screw with low friction and with maintaining torsional rigidity.
SUMMARY OF THE INVENTION The object of the present invention is to provide a device according to the preamble which provides a lattice-operated welding function which is self-lasing in both directions.
Another object is to provide a device according to the preamble which comprises feather elements intended to project the inner tube, which device provides a reliable and easily maneuvered welding function.
A further object is to provide a device according to the preamble which comprises a durable maneuverable device which can be operated with a pressure force from the user's thumb.
These objects are achieved with a device according to the preamble where the movement means comprises a cylindrical neck, on which neck a passage is arranged, where the movement means further comprises a flange with a conically shaped end surface which is directed towards the neck.

Figures 1-3 show a first wedge member 30 intended to cooperate with a welding sleeve 9 according to Figures 4-6. Save! the wedge member 30 as the welding sleeve 9 is suitably made of thermoplastic material with suitable strength and flexibility. The wedge member 30 comprises a fixed neck 33 intended to be pushed into a spirit on an inner tube 1 and fixed there on a slightly set edge. The wedge member further comprises a stop flange 34 intended to, in cooperation with a stop sleeve on one end of an outer tube 3, prevent the wedge member from falling out of the outer tube. The stop flange is formed on its upper part to a first wedge 14 with substantially tangentially directed wedge surfaces 15 and which wedge ends with a stop lug 108. At an angle of 180 degrees around the circumference of the guide pin 32, another stop lug 108 is arranged. In the wedge 14 and the stop flange 34, recessed axially directed guide pairs 31 are intended to co-operate with longitudinal lugs 8 on the inside of the outer tube 3, which are shown in figure 19. Said co-operation means that the wedge member is prevented from turning relative to the outer tube under axial weiser. The wedge 14 is formed as an outgrowth of a cylindrical guide pin 32 which is open at the front and with a recess 105 at the rear, which guide pin extends from the stop flange 34 up to a front and up Open sleeve 106. This sleeve 106 forms a housing for a second wedge means 30 'with a second wedge 14', which are described in more detail later. The sleeve 106 comprises an axially directed guide pair 31 Mr cooperating with lugs 8 as described above. On its upper part the sleeve ends with a support surface 107 intended to receive a downward force from a spring element 120. The wedge member 30 is essentially cylindrical in shape and has a passage hole 36 in which an internal passage 35 with a large pitch is arranged. The welding sleeve 9 is preferably made of a thermoplastic material with suitable strength and flexibility. The welding sleeve 9 comprises two rings with essentially cylindrical welding surfaces 37 and 37 ', respectively. The longitudinal axes of these rings coincide and the rings are held together at a certain axial distance from each other by means of a neck 38. The neck 38 is broken on most of its circumference so that two narrow bridges are formed. The purpose of this is to keep the rings with the laser surfaces 37 and 37 ', respectively, axially inclined without being able to influence each other in the name where one of the rings has expanded radially. The radial action takes place on the edge set by pushing the first wedge 14 into the wedge-shaped recess 113 of the welding sleeve 9 and the second wedge 14 'is pushed into the corresponding wedge-shaped recess 113'. Thus, the wedge surfaces 15 and 15 'of the wedges 14 and 14', respectively, will be displaced relative to the wedge surfaces 16 and 16 'of the welding sleeve 9, the substantially cylindrical welding surfaces 37 and 37' of the welding sleeve 9 increasing the diameter.
Figures 7-10 show a second wedge member 30 'which is preferably made of a thermoplastic material with suitable strength and flexibility. The wedge member 30 'is substantially tubular with a passage hall 111 which hl in the lower part ends with an inner flange 112 with a smaller inner diameter than the hole 111. In the upper part of the wedge member 30' a conically shaped surface 110 is arranged. the wedge member 30 'is a wedge 14' with substantially tangentially directed wedge surfaces 15 'arranged. In said wedge 14 'an axially directed guide pair 31 is recessed. The wedge 14 'ends at the lower 4 part with a stop lug 108'. On the opposite side of the wedge 14 ', 180 degrees along the circumference of the wedge member 30', said wedge member is partially broken by a slot 114, which is damaged Figure 13. Said slot 114 extends from the lower end of the wedge member 30 'up to just below the conically shaped surface110. On circumferential sides of the slot 114 and on the lower part of the wedge member 30 ', stop lugs 108' are arranged.
Figures 11 and 12 show a movement member 41 which comprises a cylindrical neck 49 with a slightly smaller outer diameter than the passage hall 111 of the wedge member 30 '. On the lower part of the neck 49 a pair of passages 42 is arranged. Said neck also comprises an annular recess 43, which recess defines a lower stop surface 44. The outer diameter of the recess 43 is slightly smaller than the inner diameter of the inner flange 11 'of the wedge member 30'. The movement member 41 further comprises a flange 45, preferably arranged on the upper part of the neck 49. which flange comprises a conically shaped end face 46 with substantially the same cone angle as the conically shaped surface 110 of the wedge member 30 '. It is preferred that said conically shaped end face be directed towards the neck 49. Along the long axis of the movement member a passage hall 47 with a non-circular cross section is arranged.
Figure 13 shows how the second wedge member 30 'is mounted on the moving member 41. The mounting takes place through the wedge member 30' being pulled on the lower part of the neck 49 of the moving member 41. [Again, said wedge member is pushed upwards with the slot 114 widening to allow free passage of said flange 112. When the flange 112 has reached the groove 43, the flange 112 snaps into the annular groove 43. The lower axially directed surface of the flange 112 of the wedge member 112 abuts the lower stop surface 44 of the moving member 41. The conically shaped surface of the wedge member 30 ' 110 takes a stand against the conically shaped end face 46 of the movement member 41 on the flange 45. These two surfaces 44 and 46 are at such an axial distance that all the wedge member 30 'can rotate freely on the movement member 41 with a certain axial play so that said conically shaped surface 110 takes time. against said conically shaped face 46 as the wedge member 30 'is moved relative to the rudder member 41 in the direction of the arrow A.
Figures 14 and 15 show a spring support 115 formed as a cylinder broken in the axial direction with a lower inner flange 116. The outer diameter of said cylinder is slightly smaller than the inner diameter of the outer tube 23. This flange 116 is intended to constitute a stop for the spirit of an axially acting spring element 120, which spring element then takes a ski towards a seat 117. The lower axially directed surface of the spring support 115 defines an engaging surface 118 for the force of the spring element 120. The upper part of the spring support 115 is formed as a shell for all internally offering a radial support for said spring element. On the outside of the spring support an axially directed guide pair 31 is arranged.
Figures 16 and 17 show a mounted welding member 4 comprising the first wedge member 30. Outside the wedge member 30, the welding sleeve 9 is patterned from the Owe spirit of the wedge member, Over the sleeve 106. Delia is possible because the welding sleeve 9 is flexible and slotted with an axially directed groove. When the locking sleeve 9 is pulled onto the wedge member 30, it is rotated so that all the wedge-shaped recess 113 fits into the wedge 14 and snaps over the stop lugs 108. When the locking sleeve 9 is thus in place, the movement member 41 with mounted second wedge member 30 'is screwed into the first wedge member 30. in such a way that the wedge 14 'is pressed in, the wedge-shaped socket 113' of the welding sleeve 9 so that it snaps over the stop lugs 108 '. Figures 16 and 17 show sectional partial views of the inner tube 1 and the outer tube 3.
The inner tube 1 has a first free spirit in the direction of the arrow J, which is not shown in Figures 16 and 17. The figure shows how the second spirit of the inner tube 1 is patterned on the retaining neck 33 of the first wedge member 30 and fixed there at an edge with which the welding member 4 is arranged on the second spirit of the inner tube 1. The inner tube 1 is protruding from a first spirit of the outer tube 3, which spirit is not shown in Figures 16 and 17. The outer tube is a patter outside the welding sleeve 9 and the wedge members 30 and 30 '. In this case, the outer tube 3 is rotated on such a sail. All longitudinal lugs 8 according to Figure 19 are inserted in guide pairs 31. Thus, the locking member 4 is in its entirety secured against rotation relative to the outer tube 3. As a result of this rotary fuse, the inner tube 1 is also secured against rotation relative to the outer tube. 3. In the layer shown in Figures 16 and 17, the welding means 4 is in a loaded position. The wedge means 30 'are then unscrewed, with the aid of the cutting means 41, to an outermost layer. Some layers arising through the stop lugs 108 'of the wedge member 30' pull the welding sleeve 9 up to the layer where the welding sleeve 9 is further prevented by the wedge member 30 stop lugs 108. In this case, the outer diameters of the laser sleeves 9 and 37 'are smaller than the inner diameter of the outer tube. a radial gap 109 arises. Thus, the welding member 4 with mounted inner tube 1 can be moved freely in the axial directions relative to the outer tube 3.
The axial movement of the wedge members 30 and 30 'relative to each other is effected by the actuating member 41 being rotated about its longitudinal axis. The aisle pair 42 on the movement member 41 is passed out of or into the passage 35 on the wedge member 30. This rotational movement is effected through the pivot rod 7 inserted in the passage hall 47 through the movement member 41. Said pivot rod has a non-circular cross section which fits said passage hall with a certain radial play so that the movement member 41 can be moved freely in the axial direction relative to the pivot rod 7 and so that all the movement member is rotated when the pivot rod is rotated about its longitudinal axis. When the pivot rod 7 is rotated in the direction of the arrow M, the movement member 41 is screwed into the first wedge member 30. Thereby the second wedge member 30 'is moved axially in the direction of the first wedge member 30. When this happens the wedge member 30' rotates around the movement member 41. At said axial movement the wedges 14 and 14 'into the wedge-shaped recesses 113 and 113' of the welding sleeve 9, respectively. Thereby, the radius of the welding surfaces 37 and 37 'of the welding sleeve 9 increases until they come into contact with the inner jacket wall of the outer tube 3. The welding member 4 with mounted inner tube is then loaded in the axial direction relative to the outer tube 3. As the inner tube 1 is displaced in the direction of the arrow relative to the outer tube 3, the wedge member 30 wedge 14 will all be pressed deeper into the wedge sleeve 9 wedge shaped recess 113. Thus the wedge 14 wedge surfaces 15 are moved axially in arrow In the direction along and relative to and relative to the welding sleeve 9 cooperating wedge surfaces 16. This movement meant that the welding surface 37 of the welding sleeve expands further with Okad welding function as follows. The result is self-welding of the inner tube 1 relative to the outer tube 3 in the direction of the arrow.
As the inner tube 1 is displaced in the direction of the arrow J relative to the outer tube 3, the wedge member 30 'wedge 14' all is pressed deeper into the wedge-shaped recess 113 'of the welding sleeve 9. Thereby, the wedge surfaces 15 'of the wedge 14' are moved axially in the direction of the arrow J along and cooperating with the wedge surfaces 16 'of the welding sleeve 9. This movement meant on the same sail as above that the welding surface 37 'of the welding sleeve expands further with the increased welding function as follows. The result is self-welding of the inner tube 1 relative to the outer tube 3 in the direction of the arrow J.
In order to achieve a certain axial displacement of the wedge 14 relative to the recess 113, the second wedge 14 'must be moved equally rigidly relative to the corresponding recess 113'. This meant that all the movement means 41 had to be moved twice as long as the axial distance relative to the wedge means 30. With a pitch of the passage 35 which is sufficiently small for all to be self-locking, this is required as the pivot 7 is rotated so much that it causes problems 6 with maneuvering. It is then Onskvart to Oka gangstigningen. Such an increase did not cause any problems with the mantle torque because the only thing required is that the welding surfaces 37 and 37 'of the welding sleeve expand to contact with the inner mantle surface on the outer tube 3. No welding force needs to be applied because the welding effect occurs due to self-welding. However, a sufficiently large aisle slope to obtain good maneuverability means that the aisle pair 42 does not become self-locking in the aisle 35. The consequence is then that the movement member 41 is unscrewed spontaneously under load on the inner tube 1 relative to the outer tube 3 in the direction of the arrow J. This loses the load function. To solve this problem, previously explained arrangements with conical surfaces 46 and 110 have been introduced on the movement member 41 and the second wedge member 30 ', respectively. Referring to Figure 13, the second wedge member 30 'is displaced in the direction of the arrow A relative to the moving member 41, a friction arises between the conical surfaces 46 and 110. At a sufficiently large cone angle, this friction can become so large behind the moving member 41, despite a large step , is not unscrewed spontaneously under load on the inner tube 1 relative to the outer tube 3 in the direction of the arrow J according to Figures 16 and 17. It will be appreciated that the same friction-increasing effect can be achieved by arranging a conical seat in the passage of the first wedge member 30, the second wedge member 30 'can be designed with an inner passage. Furthermore, the conical surfaces 46 and 110 can be formed on another sail, e.g. so the fixture 45 includes a conically shaped groove on the side facing the neck 49.
Figures 16 and 17 also show a spring element 120, designed as a compression spring. The spring element 120 runs on the inside of the outer tube 3 and can be guided radially with support elements. The spring element 120 is preferably axially fixed in the upper part of the outer tube 3 and takes in its lower end ski against a seat 117 arranged on the spring position 115 as described above. Said spring support is fixed against rotation relative to the outer tube 3 so that a lug 8 on the outer tube 3, according to figure 19, is inserted into the guide pair 31 of the spring support according to figure 15. The spring support 115 can run freely inside the outer tube 3. The force of the spring element 120 on the welding member 4 The support surface 107 takes place via the contact surface 118 of the spring support 115 in the direction of the arrow J, in the direction of the first free spirit called the inner tube 1. The spring element 120 has such a length that it affects the welding member 4 during at least a part of the majestic axial displacement distance, but preferably during the entire displacement distance. Thus, the inner tube 1 will be pushed out from the outer tube 3 when the welding member 4 is moved to the unloaded position. It is then of great importance that the forces which the spring element 120 exerts on the laser means 4 do not justify the operation of the laser means. There are four possibilities for applying the force from the spring element 120; it can be on the movement means 41, on the second wedge means 30 ', on the welding sleeve 9 or on the reading means 30. Applying said force to the moving means 41 is obviously inappropriate as it would justify the rotation. But which of the remaining three other possibilities is best is not clear. Practical tests have shown that the function is best if the said force is applied to the first wedge member. This is slow because you then need a structure on the wedge member 30 which builds the upper part Mr of the passing member 41 to provide a support surface 107 which can be reached by a spring support attack surface 118. It is essential for the good function that one of the ends of the spring element 120 a seat 117 which is fixedly fixed relative to the inner tube 1 in the direction of the arrow J, that is to say in the direction of said first spirit of the inner tube 1. The coil spring shown in the figure can of course be replaced by other types of spring elements. Figures 18 and 19 show the outer surface 3 with internal longitudinal lugs 8, which lugs in cooperation with the previously mentioned guide pairs 31, allow a rotational fixation of the welding member 4 relative to the outer surface 3. Such a rotary fixation can of course be achieved in another way, e.g. by longitudinal internal grooves in the outer tube 3 free * interaction with longitudinal lugs comprising in the welding member 4. The hord part with such an arrangement could be able to achieve a better radial control of a spring element 120, inserted in the outer tube 3.
Figures 20 and 21 show an actuator 5 suitably made of a thermoplastic material with suitable strength and rigidity. Said actuator comprises a head 91 which is substantially cylindrical with a curved pressure surface on the upper side. Two legs 92 protruding on the underside of the head 91. The legs 92 comprise at the bottom two knights 93, which barrels are used towards each other. A circular through hole 98 is recessed in the feet 93, along the center axis of the head 91. On the underside of the feet 93, a tubular guide flange 96 is provided. On the upper sides of the feet 93 Al a tubular support flange 99 is arranged. Arranged between the legs 92 is a cylindrical pin 94, which pin projects from the underside of the head 91 along the center axis of said head. The underside of said pin is terminated with a conical tip 95. In the opening between the feet a gap 98 is formed, whereby the hollow 97, the guide flange 96 and the support flange 99 are each divided into two halves.
Figures 22 and 23 show a guide screw 80 intended for co-operation with said operating means and preferably made of a thermoplastic material. The roller screw 80 comprises a cylinder 81, on the cylindrical circumferential surface of which an external thread 82 is arranged. It is preferred that the corridor has a relatively large slope and that it has several entrances. Furthermore, the aisle 82 has an opposite orientation compared to the aisle 42 of the movement member 41, in that if the aisle 42 forms a right-hand aisle, the aisle 82 constitutes a left aisle. The corridor shown in the figures has four entrances. Along the center axis A1 * of the cylinder 81 a bottom hall 83 is received from the first spirit of a screw screw 80, which is seen from the underside of the cylinder 81. Said bottom hall is intended to receive the upper spirit of the pivot rod 7 and has suitably the same, but somewhat larger, cross-section as the pivot rod 7. The pivot rod 7 can be fixed against extraction from the bottom tail 83 on an edge set, e.g. by welding with a screw or pin inserted I, a radius 84 directed on the cylinder 81. The roller screw 80 also comprises a pin 86, which pin is arranged on the upper side of the cylinder 81. The center axis of said pin coincides with the center axis of the cylinder 81. The pin 86 further comprises a flange 87, which flange is thus arranged on the second end of the screw screw 80. Arranged in the center of the upper axially directed surface of the pin 86 is a recess 88, intended to receive the tip 95 of the actuator 5. When mounting, the pin 86 is inserted into the gap 98 between the frit 93 of the actuator 5, the legs 92 being bent outwards after which the pin 86 snaps into the actuator. 5 hal 97. Thereby the upper sides of the feet 93 are hooked into the flange 87. Thereby the support flange 99 of the operating member 5 stands on the underside of said flange 87 and the tip 95 of the operating member 5 is inserted into the recess 88 of the pin 88. play, relative to the agitator screw 80, while the actuator 5 is freely rotatable relative to the agitator screw 80.
Figures 24-26 show a nut 100 preferably made of a thermoplastic material with good sliding properties in relation to the material used in the roller screw 80. The nut 100 comprises a tubular hat 12 with a slightly smaller outer diameter than the inner diameter of the outer tube 3. The neck 12 comprises a passage hall 101, in which passage hall an internal passage 102 is arranged. The passage 102 has a sac: The shape of the passage 82 of the screw screw 80 fits into it with a certain play. On the outside of the neck 12 of the nut 100, axially directed grooves 18 are arranged, in which grooves the outer lugs 3 of the outer tube 3 fit. The minimum number of grooves 18 is as many as lugs 8. The nut 100 also comprises a flange 103 arranged on one end of the neck 12, which flange has a larger outer diameter than the outer diameter of the neck 12.
Figure 27 shows a mounted operating device 85 comprising an outer tube 3, a nut 100, an actuating screw 80, an operating member 5 and a compression spring 122. Furthermore, the figure shows parts of a pivot 7 and a tader element 120. The mounting takes place in cooperation with a the outer tube 3 is inserted into the welding means 4 according to Figures 16 and 17 when one thinks of the outer tube 3 continuing upwards in the direction of the arrow J towards the second spirit of the outer tube 3, which spirit is shown in Figure 27 and is opposite said first spirit. In the outer tube 3 the spring element 120 is also inserted and preferably extends from the seat 117 to the underside of the nut 100. When the spring element 120 and the locking member 4 with paired inner tube 1 are inserted in the outer tube 3, the operating device is mounted mounted on the rotating screw 7. hal 83 and fixed there on the edge set. Then the stirring screw 80 is mounted on the actuator 5 as previously described and the neck 12 of the nut 100 is retracted into said second spirit of the outer tube 3. The nut 100 shall not be fixed in the outer tube 3. In this layer the next pressure spring 122 is outside the stirring screw 80 and then the pivot rod 7 through the nut 100. The pivot rod must then be rimmed into the passage hall 47 of the rudder member 41, after which the thread 82 of the rudder screw 80 is pulled into the cooperating thread 102 of the nut 100. The nut 100 guide pair 18 then needs to be lifted out of the outer tube 3 lugs 8. nut 100, can be rotated freely. The next step is to rotate the pivot rod 7 in the direction of the arrow R by means of the stirring screw 80. The pivot rod is then rotated in the direction of the arrow M according to Fig. 16, whereby the welding means 4 is brought to the load position as previously described. Thereafter, the nut 100 is rotated in the direction of the arrow R, whereby the stirring screw 80 is screwed into the nut 100 while the compression spring 122 is compressed between the upper side of the nut 100 and the lower side of the actuator 5. The upper threads of the compression spring 122 thereby enclose the guide flange 96 of the control member 5. On that sail, the legs of the control member 5 are loaded so that it cannot! Am out frail each other which could result in the flipper 93 of the control member 5 losing grip on the flange 87 flange 87. Finally Mrs nut 100 down into the second spirit of the outer tube 3, the lugs 8 of the outer tube being fitted into the guide pair 18 of the nut 100, after which the nut 100 is read against the outer tube 3 on the edge set. It is suitable that the nut 100 has several guide pairs 18 with even pitch so that there are several possibilities to choose how much compression spring 122 is to be compressed. The thus-compressed compression spring 122 will again exert a projecting force on the actuator 5 relative to the nut 100 and thus on the moving screw 80 in the direction of the arrow Q. Thereby, the welding member 4 will be held in the load position with a certain force between cooperating wedges 14 and 14 '. When the actuator 5 is pressed in the direction of the arrow P, in the direction of the first free spirit of the inner tube 1, the tip 95 of the actuator 5 will push against the recess 88 of the stirring screw 80. Due to the small radius of the pressure surface, the friction torque will be very small and the stirring screw 80 will be pressed. in the nut 100 while rotating in the direction of the arrow S while the compression spring 122 is further compressed. Thereby, the welding member 4 will again be moved to a load position and the inner tube 1 will again be pushed out of the first spirit of the outer tube 3. When the actuator 5 is released, the compression spring 122 will press the actuator upwards in the direction of the arrow Q, whereby the support flange 99 of the actuator 9 presses the flange 87 of the moving screw 80 upwards. Due to the small radius of the pressure surface, this friction torque will also all be very small and the movement screw 80 will all be pressed upwards in the nut 100 while it rotates in the direction of the arrow R, with which the locking member 4 returns to the load position. This operation presupposes that all the welding means 4 are rotatably secured relative to the outer tube 3. In order to provide a practically more manageable mantivating device 85, a WO is required around the guide screw 80 and also partly around the legs 92 of the operating member 5, which oil can be gripped by the operator. arrow P direction. Thus, a one-handed maneuvering welding function can be achieved.
The maneuvering device 85 described above can, of course, be used to maneuver other types of telescopic lasers. One can, for example, fill a weld with a weld sleeve 9 with only one weld surface 37 and a wedge-shaped recess 113 as described in WO2009 / 102260. Furthermore, it is possible to imagine that all the stirring screw 80 is affected by a torsion spring.
The invention as described and obvious to those skilled in the art will now be summarized in the following claims.
