    [0008] This description describes a wick assembly 100 having a wick accessory and a wick. The wick may be that of FIG. 1, but the wick having a connecting rod or the wick of FIG. 7. FIGS. 1 to 3 show a wick 200 and a wick accessory 100 used with the wick 200. wick accessory 100 comprises a sleeve 110, an installation slide 120, a stop portion and an operating member 140. The installation slide 120 is a body of revolution rotatable around its central axis. To easily introduce the technical solution of the present description, the following definition is given: the central axis around which the installation slide rotates is defined as a first axis Y, the direction of the first axis Y and the direction parallel to the first axis Y is defined as the axial direction, the circumferential direction about the first axis Y is defined as the circumferential direction, in the axial direction one end toward the operating element 140 is defined as the front, and the other end is defined as the back. The foregoing definitions do not limit the scope of this description in any form whatsoever.
    [0009] As shown in Figures 2 and 3, the sleeve 110 serves as a main support part in the wick accessory 100, and a housing cavity 111 for the wick 200 to pass through is disposed therein. The housing cavity 111 passes through the whole of the sleeve 110. The sleeve 110 comprises a sleeve body 112 and an end cap 113. The body of the sleeve 112 comprises an outer wall and an inner wall forming the housing cavity 111. The housing cavity 111 extends in the axial direction. The end plug 113 is disposed on a rear end of the sleeve body 112, and includes a cover portion 113a and a connecting portion 113b. The middle portion of the cover portion 113a is provided with an insertion hole 113c allowing the wick 200 to pass through. The cover portion 113a is provided with the insertion hole Po9 113c so that the cover portion 113a can in part covering the rear end of the housing cavity 111. The diameter of the insertion hole 113c is smaller than the outside diameter of the installation slide 120. The connecting portion 113b is fitted on the outer wall of the body The connecting portion 113b is an internally threaded portion having internal threads and the end portion of the sleeve body 112 is an outer threaded portion having outer threads on their outer wall. With the interplay of the inner threads and the outer threads, the end cap 113 can be reversibly attached to the sleeve body 112. As such, the installation slide 120 can be replaced according to the requirements. It will be appreciated that the end cap 113 may also be attached to the sleeve body 112 by a snug fit. The sleeve 110 may be of transparent material, and a fluorescent material may also be added in the transparent material. As such, when the wick accessory 100 is used in a relatively dark area, it can illuminate the work area.
    [0010] The sleeve body 112 is further provided with a limiting portion 112a, and the limiting portion 112a is disposed between the operating member 140 and the installation slide 130. When the wick accessory 100 is fitted onto the wick 200, the limiting portion 112a can prevent the wick 200 from going further with respect to the sleeve body 112. The formation of the limiting portion 112a allows the wick accessory 100 of the present description to be used with the wick 200 of Figure 1, and the limiting portion 112a cooperates with a shoulder portion of the wick 200, so that the length of the wick 200 passing through the sleeve 110 is limited. The installation slide 120 is received in the housing cavity 111 and can move in a determined interval in the housing cavity 111 along the direction of extension of the housing cavity 111, i.e. that the installation slide 120 can move forward and back in the axial direction. The installation slide 120 comprises a sleeve portion 121 disposed in the inner circle through which the installation slide 120 can resiliently cover the outer periphery of the wick 200. In the example illustrated, the section of the installation slide 120 in the circumferential direction has an annular structure, and the axial length of the installation slide 120 is between 0 and 20 mm. It is preferred that the axial length of the installation slide 120 be between 5 and 20 mm. The installation slide 120 of a certain length allows the wick 200 and the sleeve 110 to be mutually parallel. In addition, to allow the slide part 121 to resiliently cover the wick 200, the installation slide 120 is made of an elastic material, for example a rubber-based material, so that the installation slide 120 can be fitted with in a tight manner on the wick 200. The sleeve 110 further comprises an abutment portion for preventing advancement and retraction of the installation slide 120 to the end position along the axial direction in the housing cavity In particular, the abutment portion comprises a first abutment portion 131 and a second abutment portion 132. The first abutment portion 131 serves to prevent the installation slider 120 from advancing in the axial direction relative to the housing cavity 111, which prevents the installation slide 120 from completely out of the sleeve 110 from a front end. The first abutment portion 131 is disposed within the sleeve body 112 and at the forward end in the axial direction of the housing recess 111. The first abutment portion 131 includes a first annular surface 131a which is a surface sleeve body 112 extending inwardly into the housing cavity 111. The second abutment portion 132 serves to prevent the installation slide 120 from receding further in the axial direction relative to the housing cavity 111. The second abutment portion 132 is disposed at the rear of the sleeve body 112. The second abutment portion 132 includes an annular surface 132a which is formed by the inner side of the cover portion 113a. The second abutment portion 132 is part of the cover portion 113a. The operating element 140 is disposed at the front end of the sleeve 110.
    [0011] The wick accessory 100 may have various functions depending on the different operating elements 140. To tighten the screw by hand without supporting the screw by hand, the operating element 140 is a ring carrying magnetism. In addition, to attract the screw, the ring is a magnet installed in an open installation groove (not shown) disposed at the front end of the sleeve 110. The magnet is a hollow cylinder which allows the interior of the housing like to communicate with the housing cavity 111. As such, the wick accessory 100 is fitted onto the wick 200 and the wick 200 moves near the screw, the screw can be attracted to the magnet of the wick. the wick accessory 100, which allows operation of a hand without having to support the screw by hand. In addition, the operating element 140 may also correspond to other devices depending on the function of the wick accessory 100. The operating element 140 may for example be a light source, so when the wick accessory 100 is fitted on the wick 200, it can shine during operation in dark areas. The sleeve 100 may also be made of aluminum or plastic, so as to prevent the magnetism of the magnet and thus affect the effect of the attraction of the screw. The wick accessory 100 is fitted on the wick 200. When the screw has to be tightened, the wick 200 is brought closer to the screw, then the screw is fixed firmly to the wick 200 by the magnet of the wick accessory. 100, so that the wick accessory 100 can be operated with one hand without manipulating the screw by hand. In addition, the installation slide 120 of the present description can advance and retrace along the axial direction in the housing cavity 111. As such, the wick accessory 100 is fitted onto the wick 200, if the position is not precise, so that the magnet is far from the screw and can not attract the screw completely, as the installation slide 120 can move forward and backward relative to the sleeve body 112 and that the slide 120 is fitted on the wick 200, the sleeve body 112 and the magnet can automatically advance the screw relative to the wick 200 under the action of the magnetic force, the screw can thus be attracted more easily, without having to further adjust the position of the wick accessory 100 on the wick 200, allowing operation of one hand to tighten the screw. The wick accessory 100 and the wick 200 constitute a wick assembly 10. The wick 200 passes partially through the housing cavity 111, and the installation slide 120 covers the wick 200. The wick accessory sleeve 110 100 has a limiting portion 112a, and the wick 200 further comprises a staggered structure 210 for cooperation with the limiting portion 112a. The staggered structure 210 may be the shoulder portion of the wick 200. With the support of the limiting portion 112a and the staggered structure 210, the wick 200 is prevented from passing through the wick accessory 100 and advancing further relative to to the accessory for wick 100.
    [0012] As shown in Figures 4 to 6, for another wick 400 having a connecting rod 420 in another wick assembly 20, there is another wick accessory 300 used for the wick 400. An installation slide 330 is fitted in the wick accessory 300 on the connecting rod 420. A second limiting portion 311b is formed by extending a first abutment portion 311 extending inwardly into the interior portion of a housing cavity 311. The second limiting portion 311b cooperates with a second staggered structure 421 disposed on the connecting rod 420 to further prevent the wick 400 from traversing the inner portion of the wick accessory 300 relative to the wick accessory 300. wick accessory 300 is not used only for the wick 400 with the connecting rod, but also serves for the wick 200 of FIG. 1. The other structures of the wick accessory e 300 are the same as those of the wick accessory 100. As shown in Figures 7 to 10, to expand the application of this description, for another wick 600 of FIG. 7 in another wick assembly 30, there is another wick accessory 500 used for the wick 600. The wick accessory 500 has a structure that is generally the same as that of the wick accessory 100, and the difference it is furthermore provided with a limiting element 550. The limiting element 550 limits the length of the wick 600 passing through the wick accessory 500 and projecting therefrom. The limiting member 550 is provided with a limiting hole 551 extending through the limiting member 550. The limiting hole 551 further includes a first hole wall portion 552 and a second hole wall portion 553. The first wall portion Hole 552 serves to form a hole wall of the limiting hole 551 with a minimum hole diameter, and the second hole wall portion 553 serves to form a hole wall of the limiting hole 551 with a maximum hole diameter. The limiting element 550 is disposed in a housing cavity 511 of a sleeve 510, and installed in the housing cavity 511 from the rear end of the housing cavity 511, while a first abutment portion 531 of the housing cavity 511 can prevent the limiting element 550 from still emerging from the housing cavity 511 from the front end, the limiting element 550 is thus installed in the housing cavity 511. When the element Limiting 550 is in the installed position stopped by the first abutment portion 531, the direction in which the limiting hole 551 passes through the limiting element 550 is also parallel to the housing cavity 511, i.e. direction in which the limiting hole 551 passes through the limiting element 550 is also parallel to the direction of extension of the housing cavity 511. In particular, the direction in which the housing cavity 511 passes through the element The limiting limit 550 is also parallel to the first axis Y. It should be noted that in the present description, the description of the structure of the limiting element 550 is based on the reference state in which the limiting element 550 is in position. of installation, but this description does not limit the scope of this description of any kind. Moreover, as for the direction in which the limiting hole 551 passes through the limiting element 550 and the extension direction 15 of the housing cavity 511, it will be noted that if the area surrounded by the limiting hole 551 or the housing cavity 511 is considered a dummy entity, the center axis direction of the entity corresponds to the direction in which the limiting hole 551 passes through the limiting element 550 or the direction of extension of the housing cavity 511. In particular, the thickness of the limiting element 550 in the axial direction is between 0.1 and 5 mm, and it is relatively thin. The first hole wall portion 552 and the second hole wall portion 553 are disposed in the same axial position in the limiting hole 551, i.e., if the thickness of the first hole wall portion 552 and the second hole wall portion 553 in the axial direction is ignored, then the first hole wall portion 552 and the second hole wall portion 553 are in the same plane perpendicular to the first Y axis, thus the first the hole-wall portion 552 and the second hole-wall portion 553 of the limiting hole 551 may be considered as an inner circle of the section of the limiting member 550 perpendicular to the first axis Y. In addition, an outer circle of the section is round. At the inner circle, the first hole wall portion 552 and the second hole wall portion 553 are alternately disposed in the circumferential direction of the limiting hole 551, and the first hole wall portion 552 projects from the second hole wall portion 553. The first hole wall portion 552 includes an inner arc edge 552a and straight edges 552b. The inner edge 552a is an arc having a first radius and two straight edges 552b are respectively disposed on both sides of the inner arc edge 552a. The two ends of the inner arc edge 552a are respectively connected to one end of each straight edge 552b on both sides, and the other end of each straight edge is connected to the second hole wall portion 553. The second portion Hole wall 553 includes an outer arc edge 553a having two ends to right edges 552b. The outer arc edge 553a is an arc whose second radius is larger than the first radius, thus the distance between the inner arc edge 552a and the first Y axis is smaller than the distance between the arc edge 553a and the first Y axis, and thus the first hole wall portion 552 projects from the second hole wall portion 553. It is preferred that the limiting member 550 be made of steel, which allows the Limiting element 550 has a high hardness and good wear resistance. As shown in FIGS. 7, 9 and 10, firstly, the wick 600 is introduced into the housing cavity 511 through the insertion hole 513c of the end cap 513 and passes through the installation slide 520, the limiting element 550 and the operating element 540, until it projects in part from the sleeve 510. To limit the length of a head 610 of the wick 600 which protrudes from the sleeve 510, the limiting element 550 cooperates with the head 610 of the wick 600 to limit the position. In particular, the first hole wall portion 552 and the second hole wall portion 553 of the limiting hole 551 of the limiting member 550 cooperate with a groove 611 and with a protrusion 612 of the head 610, the first wall portion. with holes 552 in the groove 611 of the head 610 in a plane perpendicular to the first axis Y and protrusion 612 of the head 610 is in the second hole wall portion 553 of the limiting member 550, and are locked together, thus the wick 600 can only partially traverse the limiting hole 551 and come into contact with the first hole wall portion 552, which limits the length of the wick 600 protruding from the sleeve 510 of in order to prevent it from protruding excessively from the sleeve, the sleeve can then draw the screw firmly and allow operation of one hand. To lock the wick 600 with the limiting hole 551 of the limiting member 550, the dimensions of the first hole wall portion 552 and the second hole wall portion 553 of the limiting member 550 may be pre-established. For the wick 600 having a Phillips head, the radius of the first hole wall portion 552 should be smaller than the distance between the projection 612 and the center of the Phillips head and greater than the distance between the groove 611 and the center of the Phillips head, while the radius of the second hole wall portion 553 must be greater than the distance between the projection 612 and the center of the Phillips head. In addition, the chord length of the first hole wall portion 552 must be greater than the distance between two ends of the two adjacent projections 612 away from the head 610. For other bits 600, the first portion The hole wall 552 and the second hole wall portion 553 of the limiting member 550 may also be preset, so there is no need to give details here. The wick accessory 500 is not only used for the wick 600 of FIG. 7, but it is also used for the wick 200 of FIG. 1 as well as the wick 400 comprising a connecting rod 420. 500 wick is not only used for a separate wick 200, but also used for the wick integrated with a screwdriver. As for the wick 200 of Figure 1, the limiting member 550 can be locked with the shoulder portion of the wick 200 to limit the position. Then the wick accessory 500 is not provided with the limiting portion 112a of the wick accessory 100. In addition, as with the wick 400 having a connecting rod 420, the limiting element 550 can also be locked with the connecting portion between the head 410 of the wick 400 and the connecting rod 420 to limit the position. This means that the wick accessory 500 of the present description can be used with at least 95% of the ordinary wicks on the market. The ordinary wicks of the present invention correspond to the general standard wick on the market. The part near the head of the locks is for example not machined to be thinner or to have irregular shapes. To then ensure the concentricity of the wick 600 with respect to the wick accessory 500 when the wick accessory 500 is engaged on the wick 600, the end cap 513 has a limiting surface 513d extending along the wick. a direction parallel to the direction of extension of the housing cavity 511 in the insertion hole 513c, and the limiting wall surface 513d forms the part of the insertion hole 513c with a minimum hole diameter. In fact, the thickness of the end plug 513 substantially determines the length of the limiting wall surface 513d along the direction of extension of the housing cavity 511. Thus, for the length of the limiting wall surface 513d is as large as possible, the thickness of the end plug 513 must be relatively large, so that the contact surface of the limiting wall surface 513d and the side of the wick 600 is relatively large, which prevents the wick 600 to deviate from the first axis Y relative to the sleeve 510 due to the external force and the magnetic force of the magnet ensuring the concentricity. In particular, the ratio of the hole diameter of the insertion hole 513c to the length of the limiting wall surface 513d along the extension direction of the housing cavity 511 is called the reference value, preferably greater than or equal to 1.1 and less than or equal to 5.5. In addition, the length of the wall limiting surface 513d along the direction of extension of the housing cavity 511 is preferably greater than or equal to 2 mm and less than or equal to 5 mm. The limiting member 550 of the aforementioned wick accessory 500 may also be formed separately from the sleeve 510. However, according to another embodiment, the limiting element may also be integrally formed together with the sleeve. That is, the sleeve is formed with a through hole therethrough, and the through hole extends along the direction of the first axis. The sleeve further includes a first hole wall portion and a second hole wall portion in the same axial position. The first hole wall portion forms the wall portion having a minimum hole diameter, and the second hole wall portion forms the wall portion having a maximum hole diameter, and in the radial direction of the through hole, the first hole wall portion projects from the second hole wall portion. That is, according to the present embodiment, the limiting member is not separately formed, and is directly formed by the inner wall of the sleeve. As with other parts of the sleeve, in particular the abutment portion, the installation slide, the operating element and the end cap may also have the above structure. The wick accessory may also constitute the wick assembly with the wick. The foregoing illustrates and describes basic principles, main features and advantages of the present disclosure. Those skilled in the art must appreciate that the aforementioned embodiments do not limit the present description in any way. In fact, technical solutions obtained in an equivalent substitution manner or equivalent variants are all intended to fall within the scope of the claims set forth below.
