DESCRIPTION OF MODALITIES 30 The modalities of the present invention will be described below based on the drawings. FIRST MODE
    Figure 1 illustrates an impact drill as an electrical mechanical tool that is mounted with a dust collection device as a fixture. Figure 2 illustrates an impact drill alone. First, on an impact drill (1), a motor (3) is accommodated so that it is in an inclined position such that an output shaft (4) is tilted back and is in a center on one side front (the right side is defined as the front side in Figures 1 and 2) of a housing (2). This housing (2) is formed by joining a pair of the left and right half of housing. Above the engine (3), a first gear (7), a clutch (8), and a master sleeve (9) are adjusted in this order from the front side on an intermediate shaft (6) for which torque is transmitted through bevel gears (5) and (5). Above the intermediate shaft (6), a tool holder (11) that has a tip into which a drill (10) can be inserted and adjusted is rotatably supported in parallel with the intermediate shaft (6). An arm (13) provided at a periphery of the master sleeve (9) through an oscillating bearing is coupled to a rear end of a piston cylinder (12) which is loosely inserted in a posterior region of the tool holder (11 ). A striker (15) is adjusted so that it is longitudinally movable inside the piston cylinder (12) through an air cam (14) and can strike an impact bolt (16) provided in front of the striker (15). The first gear (7) joins with a second gear (17) mounted on the tool holder (11).
    Meanwhile, a handle (18) equipped with a key (19) and a key lever (20) is formed in an upper rear portion of the housing (2). A battery pack (21) that serves as a power supply is mounted below the handle (18). In addition, a lower front portion of the housing (2) constitutes a mounting part (22) that has an inclined face portion (23) parallel to the outlet shaft (4) on a front face of the mounting part (22), if it projects the front of the battery pack (21) and is mounted with a dust collector (40). Within the assembly part (22), a controller (25) that is electrically connected to a motor coil (3), the key (19), and the battery pack (21) via conduction cables (24) and (24) is accommodated. On a bottom face of the mounting part (22), a guide groove (26) is provided such that a front end of the guide groove (26) opens at the front, and the guide groove (26) extends in a longitudinal direction and is drawn back inward. In addition, in front of the controller (25), negative and positive female terminals (27) to be electrically connected to positive and negative male terminals (57) on one side of a dust collection device (40) are provided and are electrically connected using the driving cable (24).
    A rectangular docking door (28) is formed with an opening in the sloped face portion (23) in front of the female terminal (27), and a plug (29) that opens and closes the docking door (28) is provided inside the mounting part (22). The plug (29) is a blade body that has a front face designated as an inclined face that is compatible; with the slanted face portion (23) and decreases in thickness upwards. The plug (29) is supported with vertical mobility between a closed position and an open position of the locking door (28) by seats (30) respectively provided in internal faces of the left and right half of housings in order to project the from the inner faces in a vertical direction. In addition, a rotating link (31) as a rotating member is provided in a lower portion of the mounting part (22) behind the plug (29). The swivel link (31) is swiveled in a center of it by a lateral axis 32 in the mounting part (22). A connector (33) provided laterally at a front end of the swivel link (31) is loosely inserted into an inclined groove (34) which is provided in a lower portion of the plug (29) and angled down and back. Meanwhile, a fan-shaped meat (35) is formed at the other end. In addition, the rotating link (31) is incited by turning in a counterclockwise direction in Figure 2 by a torsion spring (36). Consequently, in a normal state, the cam (35) protrudes into the guide groove (26) through a penetrable hole (37) provided in a lower portion of the mounting part (22) and the plug (29) is pressed to upwards by the pin (33) and kept in the closed position of the locking door (28).
    As shown in Figure 3, the dust collection device (40) is equipped with a portion with adjusted indentation (42) which is contiguous and adjusted to a lower face and the slanted face portion (23) of the mounting part (22 ) of the impact drill (1), and has a housing (41). This housing (41) is in an inverse L-shape when viewed in a side view and composed of left and right housing halves mounted together. In a rear region of the housing (41), a motor (43) that has an output shaft (44) directed forward is laterally accommodated, and behind the motor (43), a controller (45) is provided. In addition, a dust collector fan (46) is attached to the outlet shaft (44) and accommodated in an intake chamber (47) that is defined in the housing (41) and equipped with an exhaust port (not shown) on the side . A dust box (61) formed in the housing (41) in front of the intake chamber (47) has a hinge part which is denoted by (48) and which is recessed and opens only forward. A communication hole (50) through which the articulation part (48) communicates with the intake chamber (47) on the same geometric axis as the dust collector fan (46) is formed in a partition wall (49) that constitutes a bottom of the articulation part (48).
    Meanwhile, a guide passage (51) which has an open front end and a curved U-shaped end end to extend behind the hinge part (48) is longitudinally formed above the hinge part (48). An L-shaped nozzle (52) is coupled to the front end of the guide passage (51) such that a suction port (53) provided at a distal end of the nozzle (52) projects upwards. A flexible hose (54) is accommodated so as to extend at both the nozzle (52) and the guide passage (51). A rectangular tubular duct (55) folded back in a U shape together with the shape of the rear end of the guide passage (51) is coupled to a rear end of the flexible hose (54). A distal end (56) of the duct (55) as a tubular body penetrates the dividing wall (49) and protrudes into the articulation part (48).
    Behind the hinge part (48), a pair of positive and negative male terminals (57) is formed. The male terminal (57) is a blade-shaped body that protrudes backwards and is securely connected to a backward sloping face 58 of the housing (41) and that forms a portion with suitable indentation (42). The housing (41) is provided with a protective strip (59) which is attached to a middle portion of the male terminal (57) and a distal end of the protective strip (59) projects backwards. Consequently, a portion of the base protruding from the male terminal (57) is protected by the protection strip (59). In addition, as a press member which is fitted into a guide groove (26) provided on a lower face of the mounting part (22) of the impact drill (1), a rail (60) is provided on an upper rear face of the housing (41) that forms the adjusted recoil portion (42) so that it protrudes from the upper rear face and extends in the longitudinal direction. A dust box connected to the hinge part (48) is indicated by (61), including a box body (62) to which a cover body (63) equipped with a filter unit (64) is connected with a hinge . When the dust box (61) is mounted on the hinge part (48), the distal end (56) of the duct (55) penetrates an inlet (65) provided in the cover body (63), and an outlet (66) it faces the communication hole (50).
    In the impact drill (1) built as described above, when the dust collector (40) is mounted on the impact drill (1), the track (60) of the dust collector (40) is adjusted in the guide groove ( 26) on the bottom surface of the mounting part (22) of the impact drill (1) and the dust collector (40) slides back such that the adjusted recoil portion (42) is adjusted from the front of the assembly (22). Then, the rail (60) slides in the guide groove (26) to the rear, is in contiguity with the cam (35) of the rotating link (31) in the middle, and presses the cam (35) up to rotate the rotating link ( 31) clockwise in Figure 2. Consequently, the pin (33) pulls the plug (29) to the open position located below, thereby opening the locking door (28). At that moment, the pin (33) pulls the plug (29) while sliding relatively forward in the sloped groove (34) of the plug (29), so that even with the same amount of rotation, the plug (29) can be slid downwards with a greater throw due to the inclination of the inclined slot (34).
    After that, the male terminal (57) of the dust collector (40) enters the housing (2) from the open door (28), and is at the same time the mounting part (22) being fitted inside the adjusted recoil portion (42), inserted into the female terminal (27) to be electrically connected to it (Figure 1).
    Then, when the key (19) is switched on by pressing the key lever (20) of the impact drill (1), the motor (3) is driven to turn the intermediate shaft (6). At that moment, through an operation of sliding the clutch (8) from outside the housing (2), a selection can be made between a front position engaged only with the first gear (7), a rear position engaged only with the master glove (9), and an intermediate position in engagement with both the first gear (7) and the master glove (9) at the same time. This selection allows a selection between modes including a drilling mode in which the tool holder (11) rotates through the second gear (17) to rotate the drill bit (10), an impact mode in which the piston cylinder (12) is reciprocated by swinging the arm (13) and the integrated striker (15) strikes the drill bit (10) through the impact bolt (16), and an impact drill mode in which the tool holder (11) rotates and the impact bolt (16) strikes the drill bit (10) at the same time.
    Meanwhile, in response to switching on the switch (19), the controller (25) supplies power to the controller (45) of the dust collecting device (40). Consequently, the controller (45) starts the motor (43) and turns the dust collector fan (46). Then, an external air is sucked from the suction port (53) of the nozzle (52), travels through the flexible hose (54) and the duct (55) to be discharged from the inlet (65) into the housing body (62 ), and then flows through the filter unit (64). The external air reaches the intake chamber (47) from the outlet (66) through the communication port (50), and is discharged out of the exhaust port provided in the intake chamber (47). Consequently, a powdered dust produced from a material machined by the rotating drill (10) or the like, is sucked into the suction port (53), enters the housing body (62) through the nozzle (52), in the hose flexible (54), and in the duct (55) and is captured by the filter unit (64) to be trapped in the housing body (62).
    It should be noted that when the key (19) is turned off when canceling the operation of pressing the key lever (20), the motor (3) stops and then the turning (and the like) of the bit (10) stops. Meanwhile, the controller (25) is provided with a delay function of interrupting the power supply to the dust collector (40) with a delay of many seconds from the switching off of the switch (19). In the dust collection device (40), therefore, the dust collection fan (46) continues to rotate for many seconds after the drill stops. Consequently, the powder dust remaining in the nozzle (52), the flexible hose (54), and the like can also be reliably collected inside the dust box (61).
    Meanwhile, as for the removal of the dust collector (40), the dust collector (40) is slid in front of the impact drill (1) as opposed to the mounting case. Then, the dust collecting device (40) slides forward by the rail orientation (60) in the guide groove (26) and the male terminal (57) separates from the female terminal (27) to be removed from the docking door (28 ). After that, the rotating link (31) is released from pressing the cam (35) upwards by the forward rail (60), and rotates counterclockwise by inducing the torsion spring (36) and pressing the plug (29) upward through the pin (33). Therefore, the plug (29) returns to the closed position to close the locking door (28).
    As described above, in the drive source supply system according to the first embodiment of the present invention, the male terminal (57) is formed in the dust collecting device (40) in such a way that it protrudes from it, while the plug port (28) into which the male terminal (57) can be inserted, and the female terminal (27) which is located inside the plug port (28) and can be electrically connected to the male terminal (57), are provided in the impact drill (1). When the dust collection device (40) is connected to the impact drill (1) and the male terminal (57) is electrically connected to the female terminal (27), a drive source is provided from the battery pack (21) to the dust collecting device (40). That is, the drive source can be supplied at the same time that the dust collector (40) is assembled, and even after the dust collector (40) is removed, the impact drill (1) can be used by herself. Therefore, usability is excellent without any problem of switching the drive source when the dust collecting device (40) is mounted or removed.
    Especially in this case, the impact drill (1) where the female terminal (27) is formed, has the plug (29) slidable between the open position and the closed position of the plug-in door (28), the swivel link (31) which rotates by engaging one end of it with the plug (29), and the torsion spring (36) which incites the rotating link (31) in a rotating direction in which the plug (29) slides into the closed position. The dust collecting device (40) where the male terminal (57) is formed has the rail (60) that establishes a contiguity in the flesh (35) of the rotating link (31) to rotate the rotating link (31), against the incitement of the torsion spring (36), in a rotating direction in which the plug (29) slides into the open position while the dust collector (40) is mounted, and a protective strip (59) that extends along with the male terminal (57). Thus, the plug-in door (28) on the side of the female terminal (27) can be reliably opened when the male terminal (57) is connected to it, and as a result, reliability in the plug-in connection can be ensured. Furthermore, since the plug (29) is slid by the rotating link (31), a mechanism for opening / closing the locking door (28) can be formed in order to save space, not being an obstacle to make the devices compact. Furthermore, the protective strip (59) can have an effect of preventing the male terminal (57) from being damaged.
    Meanwhile, since the drive of the impact drill (1) is integrated with the drive of the dust collecting device (40), usability is further improved without any problem for the activation or interruption of the activation of the dust collecting device ( 40).
    In addition, the delay function of delaying the interruption of the activation of the dust collecting device (40) of the interruption of the activation of the impact drill (1) is provided, so that the remaining powder dust in the nozzle (52), in the hose flexible (54), and the like can be reliably collected inside the dust box (61). Thus, high dust collection performance can be achieved.
    It should be noted that the rotating link is capable of being rotated around the lateral axis in the first mode, but the rotating link can be provided by rotating around a longitudinal axis and coupled at one end of the plug, and the plug pushed down by the rotation of the rotating link, resulting from the entrance of the rail, due to a tapered face or tapered faces provided on the rear face of the rail and / or the front face of the meat on the other end of the rotating link. That is, the rotational direction of the rotating member and the way of coming into contiguity with the press member can be appropriately modified.
    In addition, it is also possible to provide the plug and the rotating member above or near the female terminal and slide the plug up or to the side to open the locking door, or the arrangement of the male and female terminals can be done in reverse from the description above. That is, it is possible to provide the power tool and the fixing device with the male and female terminals, respectively.
    Meanwhile, in the male terminal, the shape of the protection strip can obviously be changed. It is also conceivable to make, for example, such a model change so that the protective strip is retractably provided in the housing of the dust collecting device so that induction means such as a spiral spring or similar incite, in a normal state, the protection strip meets a projection position to protect the male terminal and the protection strip contacts the housing side of the power tool and recedes when the dust collector is mounted on the power tool.
    Then, another embodiment of the present invention will be described. It should be noted, however, that parts of components identical to those of the first modality are denoted by the same reference symbols, and that the same description will be omitted. SECOND MODE
    In an impact drill (1a) illustrated in Figure 4, an intermediate housing (67) is interposed between the housing (2) and the battery pack (21). An upper face of the intermediate housing (67) is fitted to the housing (2), while a lower face forms a mounting face to or from which the battery pack (21) can be mounted or removed. A terminal board (68) provided on the mounting face and electrically connectable to a battery pack (21) is connected to the controller (25) using the driving cable (24). The battery pack (21) is slid on the left in Figure 4 and mounted on the mounting face of the intermediate housing (67).
    A pin socket capable of outputting a battery pack power supply (21) to the outside is provided on a rear face of the intermediate housing (67) and can be connected by a pin plug (69a) provided on a distal end of a wire (69) which is connected and externally removed from a controller (45) of a dust collecting device (40a). The other structures of the impact drill (1a) and the dust collector (40a) are the same as those in the first modality, with the exception of an electrical connection structure of the male and female terminals.
    Consequently, in this drive source supply system, when the rail (60) is adjusted in the guide groove (26) to mount the dust collector (40a) on the mounting part (22) and the pin plug (69a) of the dust collector (40a) is connected inside the pin socket of the intermediate housing (67), a power can be supplied from the battery pack (21) to the dust collector (40a). Of course, the impact drill (1a) can itself obtain the drive source for the battery pack (21), so the impact drill (1a) can be used alone even when the pin plug (69a) is removed from the pin socket to remove the dust collector (40a).
    As described above, in the drive source supply system in the second embodiment, the drive source can be supplied almost at the same time as the dust collector (40a) is assembled, while even after the dust collector is installed (40a) can be removed, the impact drill (1a) can be used alone. Therefore, usability is excellent without any problem of switching the drive source when the dust collection device (40a) is mounted or removed.
    It should be noted that the battery pack is slid and mounted, but the battery pack can be mounted in other mounting ways such as by insertion into the housing by adjusting the mounting face of the intermediate housing according to the mounting method. In addition, the way of connecting the cable between the fixing device and the intermediate housing can be appropriately modified by changing the position of the pin socket, removing the wire from the intermediate housing to be inserted and connected inside the fixing device, or making the wire a body separate from the fixture to be inserted and connected to both the power tool and fixture, or the like. THIRD MODE *
    An impact drill (1b) illustrated in Figure 5 is an AC tool that uses a commercial power supplier as a drive source. The housing (2) accommodates an engine (70) with an output shaft (71) placed upwards in a lower front portion (the left side is defined as the front side in Figure 5). An intermediate shaft (72) to which the turn is transmitted from the output shaft (71) is located on the front side and transmits the turn to the tool holder (11). Meanwhile, a crankshaft (73) to which the swing is transmitted from the output shaft (71) is located on the rear side. An eccentric pin (74) is provided at the upper end of the crankshaft (73) in order to project from the upper end and is connected via a connecting rod (75) to the piston cylinder (12). Thus, the rotation of the crankshaft (73) is converted to a reciprocal movement of the piston cylinder (12) to allow the striker (15) to strike. In addition, a drive wheel (76) having a tapered side face down is attached to the lower end of the output shaft (71). At the lower front end of the housing (2), a window (77) that exposes the web face of the drive wheel (76) is formed vertically from the lower face of the housing (2).
    The dust collector (40b) is not equipped with the motor inside the housing (41). A distal end of the duct (55) protrudes on the rising side of a dust collecting chamber (78) that accommodates a filter (79). Meanwhile, an axis (80) is supported vertically and pivotally on the downward side of the filter (79). At a top end of the shaft (80), a dust collector fan (82) is accommodated, which is accommodated in an intake chamber (81) defined from the dust collector chamber (78). A driven wheel (83) having an upward tapering side face is attached to a lower end of the shaft (80). The driven wheel (83) exposes its side face from a window (84) formed on a lower rear face of the housing (41).
    The dust collection device (40b) can be mounted on the housing (2) from the rear face and is slid from below close to a lower front face of the housing (2) of the impact drill (1b) to engage coupling portions (not shown) ) provided on both sides of each. In this assembled state, the side face of the driven wheel (83) is pressed against the side face of the driving wheel (76) from below.
    Consequently, in the drive source supply system, when the dust collector device (40b) is slid from the bottom of the housing (2) and mounted, the drive wheel (76) and the driven wheel (83) are pressed between itself. When the key (19) is turned on by pressing the key lever (20) of the impact drill (1b) and the output shaft (71) of the motor (70) rotates, the drive wheel (76) is fully turned to turn the driven wheel (83). Consequently, the shaft (80) in the dust collecting device (40b) is rotated to rotate the dust collecting fan (82), allowing powder dust to be sucked from the suction port (53) and collected by the filter ( 79) in the dust collection chamber (78). When the pressing of the key lever (20) is canceled to stop the motor starting (70), both the output shaft (71) and the drive wheel (76) are interrupted, which are interrupted by the driven wheel ( 83), the shaft (80) and the dust collector fan (82).
    Even when the dust collection device (40b) is removed from the impact drill (1b), the driven wheel (83) is separated from the drive wheel (76), so the impact drill (1b) can be used as is.
    As described above, also in the drive source supply system in the third mode, the drive source can be supplied at the same time as the dust collector (40b) is assembled, and even after the dust collector (40b) ) be removed, the impact drill (1b) can be used alone. Therefore, usability is excellent without any problem of switching the drive source the dust collector (40b) is mounted or removed. In particular, the drive wheel (76) is provided on the output shaft (71) to receive torque, so that the dust collector fan (82) can achieve a desired turning speed without providing an acceleration mechanism.
    It should be noted that the position and shape of the drive wheel and driven wheel can be appropriately modified. For example, if the dust collection device is slid from the front of the impact drill and assembled, side faces other than tapered faces can be pressed together.
    It should be noted that the fixture in each mode is not limited to the dust collection device. For example, a lighting unit or the like equipped with an LED or the like may be acceptable. Of course, the power tool is also not limited to an impact drill. The present invention is also applicable to another type of electrical mechanical tool such as an electric drill or electric hammer.
