A yellow LED 42 </ b> A having an optical axis extending in the extending direction is provided at the distal end in the extending direction from the shaft portion 41 of the arm portion 42. A battery 42B is built in the trunk portion of the arm portion 42, and electricity is supplied from the battery 42B to the LED 42A. Further, a switch 42C is provided on the surface of the trunk portion of the arm portion 42, and electricity supplied from the battery 42B can be turned on / off. Therefore, the configuration relating to irradiation is completed with only the arm portion 42. Since the arm portion 42 is connected to the shaft portion 41 (FIG. 3), the distance between the arm portion 42 and the handle 3 can be set to two types of distances by moving the shaft portion 41 between the first position and the second position. Can be selectively set.

  In a state where the shaft portion 41 is inserted from one side into the support hole 31a of the shaft support portion 31, a male screw 43A is inserted from the other side of the support hole 31a and is screwed to the shaft portion 41 by the female screw portion 41D. The coil spring 43 is disposed between the flange portion of the male screw 43A and the inner teeth 31A of the shaft support portion 31 in a state where the male screw 43A is screwed. Therefore, the male screw 43 </ b> A is biased in the axial direction of the shaft portion 41 in a direction protruding from the opening on the other side of the support hole 31 a by the coil spring 43. Since the male screw 43A is screwed with the shaft portion 41, this urging force acts on the shaft portion 41, and the shaft portion 41 is inserted in the direction from one side to the other side, that is, in the shaft support portion 31. Biased in the direction. Therefore, unless an external force is applied such as pulling the shaft portion 41 in the extending direction, the inner teeth 31A and the outer teeth 41A are always meshed. The position of the opening portion of the second position defining portion 31C and the position of the convex portion 41B are such that the arm portion 42 extends toward the nose 21 as viewed from the shaft portion 41 as shown in FIG. The convex portion 41B is disposed so as to be disposed within the opening of the second position defining portion 31C.

Moreover, since LED42A is yellow LED, visibility is higher. Further, the convex portion 41B is inserted into the substantially C-shaped opening of the second position defining portion 31C, and the first contact portion 41E and the first position defining surface 31D are in contact with each other, that is, the shaft in the first position. Since the portion 41 can take a plurality of angles by disengaging the inner teeth 31A and the outer teeth 41A, the irradiation position of the LED 42A can be changed to some extent, and irradiation can be performed over a wider range. it can.

  Further, when the shaft portion 41 is in the first position, the arm portion 42 faces the nose 21 side. That is, since the hook portion 4 is provided at the distal end portion of the handle 3 in the extending direction from the main body portion 2, when the nail driver 1 is hooked to the hooked member by the hook portion 4, the main body portion 2 side is It can be hooked in a state of hanging from the hook portion 4. Therefore, for example, the nailing machine 1 can be stably hooked to the belt of a pants or the like by the hook portion 4.

  When the shaft portion 41 is in the first position, the distance between the arm portion 42 and the handle 3 is small, so that the nail driver 1 cannot be hooked by a hook portion 4 on a thicker member such as a single pipe. . In this case, as shown in FIG. 6, the user pulls the shaft portion 41 by hand or the like so as to resist the urging force of the coil spring 43, and disengages the internal teeth 31A and the external teeth 41A. The arm portion 42 is rotated toward the main body portion 2 side so as to be substantially parallel to the extending direction of the handle 3. When the hand is released from this state, as shown in FIG. 7, the second abutting portion 41F abuts on the second position defining surface 31E by the urging force of the coil spring 43, and the shaft portion 41 is disposed at the second position. The By arranging the shaft portion 41 at the second position, a distance between the arm portion 42 and the handle 3 can be secured, and the nailing machine 1 can be hooked on a single pipe or the like by the hook portion 4. it can. In the nailing machine 1, the main body 2 that incorporates a piston (not shown) and a cylinder (not shown) that slidably holds the piston is the most heavy. Therefore, the center of gravity of the nailing machine 1 is in the vicinity of the main body 2. Therefore, the nailing machine 1 can be stably hooked by placing the main body 2 below the hook 4.

  As shown in FIG. 7, since the inner teeth 31 </ b> A and the outer teeth 41 </ b> A can mesh with each other even in the second position, the shaft portion 41 and the arm portion 42 rotate unnecessarily with respect to the shaft support portion 31. The nailing machine 1 can maintain a stable latching state. The shaft portion 41 extends in a direction substantially orthogonal to the output shaft direction of the main body portion 2 and the extending direction of the handle 3, and an arm portion 42 is provided at the distal end of the shaft portion in the extending direction. According to such a configuration, when the nail driver 1 is hooked on a wall or the like by the hook portion 4, the wall and the surface defined by the output shaft direction of the nail driver 1 and the extending direction of the handle 3 face each other. Will do. Therefore, since the nail driver 1 and the wall are in surface contact with the nail driver 1 being hooked, the nail driver 1 can be hooked more stably.

  When the impact driver 101 is hooked on a square member or the like, the notch 143A is pressed to separate the arm 146 and the handle 103, the claw 143B is detached from the first groove 145a, and the shaft portion is urged by the urging force of the spring 147. 145 is moved and the claw 143B is hooked in the second groove 145b as shown in FIG. Thereby, as shown in FIG. 14, the impact driver 101 can be suitably hooked by the hook portion 104 even in the wide square member S <b> 2. Further, an elastomer 146A (FIG. 8) and an elastomer 103A (FIG. 13) are arranged at locations where the hook portion 104 and the handle 103 come into contact with the square member S2. Therefore, even if the square member S2 is an oblique member such as a handrail of a staircase, for example, the impact driver 101 slides on the square member S2 due to a frictional force generated between the square member S2 and the elastomer 146A and the elastomer 103A. Is suppressed, and the impact driver 101 can be suitably hooked on the square member S2. Further, since the arm portion 146 is made of an elastic material, even when the width of the square member S2 is larger than the distance between the arm portion 146 and the handle 103, the arm portion 146 can be held to a certain extent. .

  Further, when the impact driver 101 is hooked on a single pipe or the like, the notch 143A is pushed and the claw 143B is detached from the second groove 145b to further separate the arm portion 146 and the handle 103, as shown in FIG. To be hooked in the third groove 145c. As a result, the distance between the arm 146 and the handle 103 is maximized, and as shown in FIG. 16, even a wide member such as the single tube S3 can be suitably held. . Since the single pipe S3 has a circular cross section, when the impact driver 101 is hooked, the single pipe S3 may rotate in the circumferential direction of the single pipe S3. However, since the elastomer 146A and the elastomer 103A are disposed at the location where the impact driver 101 is in contact with the single tube S3, a large frictional force is generated to suppress the rotation of the impact driver 101 in the circumferential direction of the single tube S3. Can do.

  Further, even when the notch 143A is pushed too much and the claw 143B is not latched by the third groove 145c and is further urged by the spring 147, the protruding portion 145A abuts against the detachment stopper 143C, and from the hole 143a. The shaft portion 145 is prevented from falling off.

  In the power tool according to the second embodiment, the arm portion 146 is made of resin or the like. However, the invention is not limited to this, and a metal member may be used as long as it is an elastic material.

  Next, a power tool according to a third embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 17, in the third embodiment, an electric driver 201 will be described as a power tool.

  The electric driver 201 is mainly composed of a main body portion 202, a handle 203, a hook portion 204, and a battery 205. The main body 202 has a built-in motor (not shown) as an output unit, and a chuck 221 that is an output shaft driven by a motor (not shown) is provided at the tip of the main body 202. Further, the main body 202 defines an output shaft center x ′ that passes from the front end side to the rear end side and passes through the output shaft of the motor (not shown) and the chuck 221.

  From the side surface portion of the main body portion 202, a handle 203 as a grip portion is extended in a direction intersecting the output axis x ', and a battery 205 is provided at the front end in the extending direction. The handle 203 has a switch 232 at the base end of the extension, and the drive control of a motor (not shown) is performed by the switch 232. Further, a shaft support portion 231 is provided at the distal end of the handle 203 in the extending direction. The handle 203 has a gripping axis y that extends in the extending direction, and the gripping axis y intersects the output axis x '. A first virtual plane x′y that is substantially parallel to the side surface of the electric driver 201 is defined from the output axis x ′ and the gripping part axis y.

  The first virtual plane x′y includes an intersection line x that is orthogonal to the gripping portion axis y and passes through the shaft support portion 231. A normal line z of the first virtual plane x′y is extended from the intersection of the intersection line x and the gripping part axis y, and the first virtual plane x′y is extended from the gripping part axis y and the normal line z. An orthogonal second virtual plane yz is defined.

  The switch 232 is positioned on one side where the chuck 221 is disposed with respect to the second virtual plane yz, and the shaft support portion 231 is positioned on the other side opposite to the chuck 221 with respect to the second virtual plane yz. ing.

  The shaft support portion 231 is configured in a substantially cylindrical shape, and a support hole 231a is formed inside as shown in FIG. The support hole 231a extends so that an axis C of a shaft part 241 described later obliquely intersects the first virtual plane x′y, and the tip position and the base position of the shaft part 241 in the direction of the gripper axis y Are located at substantially the same position, and the front end position in the insertion direction of the shaft portion 241 is formed to be farther from the second virtual plane yz than the rear end position in the insertion direction. Further, an inner tooth 231A is provided over the entire inner surface of the support hole 231a, which is the inner surface of the substantially central portion in the penetrating direction.

  The hook part 204 is mainly composed of a shaft part 241 and an arm part 242. The shaft portion 241 is configured in a substantially cylindrical shape, and external teeth 241A are provided over the entire outer periphery of the tip portion. The shaft portion 241 is inserted into the support hole 231a and supported by the shaft support portion 231 so that the outer teeth 241A and the inner teeth 231A mesh with each other.

  The shaft portion 241 is formed with a through hole 241a penetrating in the same direction as the support hole 231a at substantially the center thereof. A screw 243A is inserted into the through hole 241a so that the flange portion is positioned on the distal end side in the shaft portion 241 insertion direction, and is screwed and fixed to the nut 243C. A spring 243B is interposed between the flange portion of the screw 243A and the position near the internal tooth 231A in the support hole 231a. Therefore, the shaft portion 241 is biased in the insertion direction by the spring 243B via the screw 243A, and the inner teeth 231A and the outer teeth 241A mesh with each other unless a reaction force against the biasing force is applied. The rotation of the shaft part 241 relative to the part 231 is restricted.

  As shown in FIGS. 17 and 18, the arm portion 242 is connected to the distal end position in the extending direction from the shaft support portion 231 of the shaft portion 241 (the rear end position in the insertion direction of the shaft portion 241). The portion 241 is substantially parallel to the intersection line x and extends toward the second virtual plane yz. As shown in FIG. 18, the distal end side position of the arm portion 242 is substantially in contact with the end surface 203 </ b> A of the handle 203. A state where the arm portion 242 is substantially parallel to the intersection line x in the hook portion 204 is defined as an accommodation position. The arm portion 242 holds a driver bit 221 </ b> A attached to the chuck 221.

  In the electric driver 201 having the above configuration, when the user is hooked to a single pipe or the like when not in use, as shown in FIG. 19, the extending direction which is a direction against the urging force of the spring 243B is used. To disengage the meshing between the inner teeth 231A and the outer teeth 241A.

  Then, as shown in FIG. 20, the arm portion 242 is rotated by an arbitrary angle toward the main body portion 202 side (FIG. 17) and moved to a latching position where the single tube S can be latched. As shown in FIG. 18, in the hook portion 204, the shaft portion 241 is pivotally supported by the shaft support portion 231 in a state of obliquely intersecting the first virtual plane x′y substantially parallel to the side surface of the electric driver 201. Therefore, in the state of FIG. 20, the rotation locus of the arm portion 242 is not parallel to the first virtual plane x′y, but is inclined. The shaft portion 241 is inclined along the intersection line x toward the second imaginary plane yz, and the arm portion 242 extends substantially parallel to the intersection line x at the accommodation position and toward the second imaginary plane yz side. . Therefore, the arm portion 242 is in the accommodation position and is closest to the first virtual plane x′y in the rotation trajectory. By rotating from this position, the arm portion 242 is moved from the first virtual plane x′y. Will be separated. Therefore, by moving the arm part 242 from the storage position to the latching position, the distance between the arm part 242 and the surface of the handle 203 is increased, and the electric driver 201 is latched so that the single pipe S is inserted therebetween. It becomes possible to do.

  Further, the fixing of the shaft portion 241 to the shaft support portion 231 is achieved by meshing of the internal teeth 231A and the external teeth 241A, so that the latching position can be any angle at which the internal teeth 231A and the external teeth 241A can mesh. Can be. Therefore, when hooking on a wide non-holding member such as a single tube, the rotation angle of the arm portion 242 is increased to increase the distance between the arm portion 242 and the handle 203, and the user's belt, etc. When hooking on a non-holding member having a narrow width, the rotation angle of the arm portion 242 can be reduced to reduce the distance between the arm portion 242 and the handle 203.

  As a modification of the power tool according to the third embodiment, a connecting portion 233 may be provided between the handle 203 and the shaft support portion 231 as shown in FIG. The connecting portion 233 includes a base portion 233A on the handle 203 side, a holding portion 233B on the shaft support portion 231 side, and a screw 233C that connects the base portion 233A and the holding portion 233B. The base portion 233A extends from a position including the first virtual plane x′y of the handle 203, and the holding portion 233B includes a pair of arms that are provided on the shaft support portion 231 and can hold the base portion 233A. ing.

  According to such a configuration, by joining the holding portion 233B to the base portion 233A from the first virtual plane x′y from one side and from the other side, the arm portion 242 is made to the first virtual plane x. It can selectively arrange | position on each surface side of one side and the other side with respect to 'y. Therefore, even when the user uses the electric driver 201 in either the right hand or the left hand, the usability of the hook part 204 can be ensured by switching the connection of the connection part 233.

  Next, the power tool which concerns on 4th embodiment of this invention is demonstrated based on FIG.22 and FIG.23. The electric driver 301 that is a power tool according to the fourth embodiment shown in FIG. 22 is substantially the same as the electric driver 201 according to the third embodiment except for the mounting position of the shaft support portion 331. The description of the configuration is omitted by adding 100 to the reference numeral of the electric driver 201 according to the third embodiment.

  As shown in FIGS. 22 and 23, the shaft support portion 331 extends so that the axis C of the shaft portion 341 obliquely intersects the first virtual plane x′y, and the shaft support portion 331 has an axis on the grip portion axis y. The front end position in the insertion direction of the portion 341 is disposed closer to the main body 302 than the rear end position in the insertion direction, and the axis C of the shaft portion 341 is substantially parallel to the yz plane including the gripping portion axis y. It is configured.

  As in the third embodiment, the shaft portion 341 is pivotally supported by the shaft support portion 331 in a state of obliquely intersecting the first virtual plane x′y. It is not parallel to the first virtual plane x′y, but is inclined. Accordingly, the arm portion 342 extends closest to the first virtual plane x′y in a state where the arm portion 342 extends in the direction away from the main body portion 302 along the grip portion axis y. By rotating so that the tip of the arm portion 342 approaches the main body portion 302 from the approaching state, the arm portion 342 is separated from the side surface of the electric driver 301 substantially parallel to the first virtual plane x′y.

  As shown in FIG. 22, the arm portion 342 is substantially parallel to the intersection line x at the accommodation position and extends from the shaft support portion 341 toward the second virtual plane yz, and is substantially close to the surface of the handle 303. From this position, the tip of the arm 342 rotates to the latching position. Since the latching position is closer to the main body 302 than the storage position, the arm 342 is moved to the latching position, whereby the arm 342 is separated from the surface of the handle 303 and the space is expanded. As shown in FIG. 2, the electric driver 301 can be hooked on the single pipe S by inserting the single pipe S between the handle 303 and the arm portion 342.

  Next, a power tool according to a fifth embodiment of the present invention will be described with reference to FIGS. The electric screwdriver 401 which is a power tool according to the fifth embodiment shown in FIG. 24 is the electric screwdriver 201 according to the third embodiment except for the configuration relating to the connection between the shaft support portion 431 and the handle 403. Therefore, the description of the configuration is omitted by adding 200 to the reference numeral of the electric driver 201 according to the third embodiment.

  As shown in FIG. 25, a rotation connecting portion 433 is provided at a portion connected to the shaft support portion 431 of the handle 403, and a portion connected to the rotation connection portion 433 of the shaft support portion 431 is provided. Is provided with a rotating shaft portion 434. The rotation connecting portion 433 is configured by a cylinder extending substantially parallel to the intersection line x from the handle 403, and a support hole 433a is formed inside. Further, an inner tooth 433A is provided over the entire inner surface of the support hole 433a on the inner surface of the substantially central portion in the hole opening direction.

  The rotation shaft portion 434 is formed in a substantially cylindrical shape extending from the side surface portion of the shaft support portion 431, and external teeth 434 </ b> A are provided over the entire outer periphery of the tip portion, and the rotation shaft portion 434. A shaft center D perpendicular to the shaft center C of the shaft portion 441 is defined in a state where the shaft portion 441 is provided on the shaft 441. The rotation shaft portion 434 is inserted into the support hole 433a so that the outer teeth 434A and the inner teeth 433A of the rotation connecting portion 433 are engaged, and in this case, the axis D and the intersection line x overlap. Become.

  In addition, the rotation shaft portion 434 has a through hole 434a formed at substantially the center thereof, and a screw 435A is inserted into the through hole 434a so that the flange portion is on the front end side in the rotation shaft portion 434 insertion direction. The screw 435A is fixed with a nut 435C. A spring 435B is provided between the flange portion of the screw 435A and the position near the inner teeth 433A in the support hole 433a. Therefore, the rotation shaft portion 434 is biased toward the insertion direction by the spring 435B, and unless the reaction force against the biasing force is applied, the inner teeth 433A and the outer teeth 434A mesh with each other so that the rotation coupling portion 433 is engaged. The rotation with respect to is regulated. Since the shaft portion 441 and the rotation shaft portion 434 are interposed between the hook portion 404 and the handle 403, two intersecting axes are provided.

  In the electric driver 401 having the above configuration, when the user is hooked to the single pipe S or the like when not in use, the shaft portion 441 is pulled in a direction against the urging force of the spring 443B as shown in FIG. The meshing between the teeth 431A and the external teeth 441A is dissociated. In this state, as shown in FIG. 27, the arm portion 442 in the accommodation position is rotated around the axis C toward the main body portion 402 (FIG. 24) (moved to the position of the arm portion 442 ′). The shaft portion 441 is fixed to the shaft support portion 431 by meshing the internal teeth 431A and the external teeth 441A.

  Then, as shown in FIG. 26, the rotation shaft portion 434 is pulled in a direction opposite to the urging force of the spring 435B to disengage the internal teeth 433A and the external teeth 434A. In this state, as shown in FIG. 27, the shaft support portion 431 is rotated around the axis D (FIG. 25) so that the tip of the shaft portion 441 moves away from the main body portion 402. In response to the rotation of the rotation shaft portion 434, the arm portion 442 'rotates away from the surface of the handle 403 and moves to the arm portion 442 "position that is the latching position, and thus the arm portion 442". Between the handle 403 and the single tube S can be inserted between the handle 403 and the arm portion 442 "so that the electric driver 401 can be hooked on the single tube S. The internal teeth 433A. Since the rotation shaft portion 434 is fixed to the rotation connecting portion 433 by meshing with the outer teeth 434A, the space between the arm portion 442 "and the handle 403 is not further expanded, and the single tube S is preferably formed. Can be held.

  Since the arm portion 442 is supported via a shaft portion 441 and a rotation shaft portion 434 that are orthogonal to each other, the trajectory of the rotation of the tip of the arm portion 442 can be configured in three dimensions. Can be provided in a state in which the arm portion 442 is separated from the handle 403 in a state where is in the latching position.

  If the handle 403 and the hook portion 404 are provided with two axes, as shown in FIG. 28, the axial direction of the axis D is substantially the same as the axial direction of the gripping portion axis y of the handle 403. You may comprise the rotation connection part 433 so that it may become parallel.

  Even in such a configuration, after the arm portion 442 shown in FIG. 29 is rotated around the axis C in parallel with the first virtual plane x′y (FIG. 28), the shaft support portion 431 is pivoted. By rotating around the center D, the arm portion 442 can be separated from the first virtual plane x′y. Since the side surface of the electric driver 401 is substantially parallel to the first virtual plane x′y, the arm portion 442 is separated from the side surface of the electric driver 401, specifically, the surface of the handle 403 even in such a configuration. The electric driver 401 can be hooked on the single pipe so that the single pipe is inserted between the arm portion 442 and the handle 403.

  Next, a power tool according to a sixth embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 30, in the sixth embodiment, an electric driver 501 will be described as a power tool.

  The electric driver 501 mainly includes a main body portion 502, a handle 503, a hook portion 504, and a battery 505. The main body 502 incorporates a motor (not shown) that is an output unit, and a chuck 521 that is an output shaft that is driven by a motor (not shown) is provided at the tip of the main body 502. The rotation axis of the chuck 521 is parallel to the output shaft direction, which is the direction from the main body 502 toward the chuck 521.

  A handle 503 that is a gripping portion extends from a side surface portion of the main body portion 502 in a direction intersecting with the output shaft direction. The handle 503 is provided with a battery 505 at the distal end of the extension, and has a trigger 532 at the proximal end of the extension. The trigger 532 controls driving of a motor (not shown).

  At the distal end portion of the handle 503, a holding portion 533 having a slit shape capable of holding a hook-like portion 541 of a hook portion 504 described later is provided. In addition, a support portion 531 that supports the hook portion 504 is defined at the tip portion of the handle 503, and the portion of the support portion 531 that supports the hook portion 504 includes an output shaft direction and an extension direction of the handle 503, respectively. A substantially parallel plane 531A is defined.

  As shown in FIGS. 30 and 31, the hook portion 504 is mainly composed of a hook-shaped portion 541, a first support member 542, and a second support member 543. As shown in FIG. 31, the hook-shaped portion 541 includes a base 541A connected to the first support member 542 and the second support member 543, and a curve continuous to the base 541A. A portion 541B and a distal end portion 541C which is continuous with the curved portion 541B and faces the base portion 541A are configured. A resin cap 541D is provided at the outermost end portion of the distal end portion 541C, and a screw hole opening in the axial direction is formed at the end portion of the base portion 541A.

  The first support member 542 is configured in a substantially L shape from a substantially flat plate-like facing portion 542A that faces the flat surface 531A and a substantially flat plate-shaped holding portion 542B that holds the base portion 541 of the hook-shaped portion 541.

  A hole 542a penetrating the flat plate is formed in the facing portion 542A, and a screw 531B is inserted into the hole 542a, and the first support member 542 is attached to the support portion 531. Since the screw 531B is screwed to the support portion 531 in a state where the screw 531B is not tightened to the flange portion, the first support member 542 causes the screw 531B to rotate around the rotating shaft while the facing portion 542A and the flat surface 531A face each other. Can be rotated as. In this case, the direction of the rotation axis of the screw 531B and the direction of penetration of the hole 542a are the same direction, and the direction of the rotation axis of the screw 531B and the plane 531A are orthogonal to each other.

  The holding portion 542B is formed with a hole 542b that passes through the flat plate. The hole 542b is formed such that its penetrating direction is substantially perpendicular to the penetrating direction of the hole 542a and its hole diameter is slightly larger than the diameter of the base portion 541A.

  The second support member 543 is configured by bending a single flat plate so as to include a pair of parallel flat plates 543A and 543B facing each other. The pair of flat plate portions 543A and 543B includes holes 543a and 543b, respectively, at substantially the center positions of the respective flat plates. The hole diameter of the hole 543b is formed to be approximately the same as the diameter of the hole 542b in the holding portion 542B, and the hole diameter of the hole 543a is formed to be smaller than the hole diameter of the holding portion 542B.

  In a state where the holding portion 542B of the first support member 542 is inserted between the pair of flat plate portions 543A and 543B of the second support member 543 and the holes 542b and 543b are arranged on the same axis, The ends of the base 541A are inserted into the holes 542b and the holes 543b. In this state, a screw 544 is inserted into the hole 543a and screwed with the base portion 541A, so that the flange portion 541 is attached to the first support member 542 and the second support member 543. Since the screw 544 is screwed to the base portion 541A without being tightened to the flange portion, the hook-shaped portion 541 is attached to the first support member 542 and the second support member 543 and the screw 544 is attached to the base portion 541A. It can be turned as a turning shaft. In this case, the rotation axis direction of the screw 544 and the penetration direction of the hole 542b are the same. A rotation axis around the screw 544 of the base 541A is defined as a first rotation axis 544, and a rotation axis around the screw 531B of the first support member 542 is defined as a second rotation axis 531B.

  Therefore, the bowl-shaped portion 541 is provided with two axes of the first rotating shaft and the second rotating shaft between the handle 503. Accordingly, since the hook-shaped portion 541 can rotate around one axis and can rotate around two axes intersecting with one axis, the locus of rotation of the tip portion 541C can be configured in three dimensions.

  When working with the electric driver 501 having the above-described configuration, as shown in FIG. 32, the hook-shaped portion 541 is rotated, and the tip portion 541C and the cap 541D are held by the holding portion 533. As a result, the hook portion 504 during operation is prevented from flapping, and the operation can be suitably performed.

  When the electric driver 501 is not used, as shown in FIG. 33, the hook portion 541 is removed from the holding portion 533 and rotated around the first rotation axis 544 so that the tip 541C is moved to the handle 503. It arranges in the position which is separated from. In this state, it is hooked on the single pipe S1.

  The electric driver 501 has a center of gravity at the position of the main body 502 because a motor or the like (not shown) is provided. The hook portion 504 is provided at the distal end portion of the handle 503 in the extending direction. Therefore, when the electric driver 501 is hooked by the hook portion 504, the main body portion 502 can be positioned below the hook portion 504 and can be hooked stably.

  Further, since the second rotation axis 531B is interposed between the hook-shaped portion 541 of the hook portion 504 and the handle 503, the main body portion 502 and the like have the second rotation axis 531B as a fulcrum. It can rotate in a pendulum shape in a direction parallel to the plane 531A, that is, the front side and the back side in FIG. Thereby, in the state where the electric driver 501 is hooked on the single pipe S <b> 1, the center of gravity of the electric driver 501 is disposed at a position where it is suspended from the hook-like part 541 without the hook-like part 541 moving. Therefore, the electric driver 501 can be held more stably.

  Further, the electric driver 501 may shake when another worker or the like contacts the electric driver 501. Also in this case, the main body 502 and the like can be rotated with respect to the bowl-shaped part 541 with the first rotation axis 544 and the second rotation axis 531B as a fulcrum. The transmission of shaking to the included hook portion 504 is suppressed. Therefore, the hook-like portion 541 is suppressed from being detached from the single pipe S1, and the stability of the electric driver 501 in the latched state can be increased.

  When the non-holding member is significantly smaller than the opening width of the hook-shaped portion 541 shown in FIGS. 32 and 33 (the width between the base portion 541A and the tip portion 541C), as shown in FIG. The bending portion 541B is bent to bring the distal end portion 541C closer to the base portion 541A. As a result, when the hook-like portion 541 is hooked on the wood S2 having a smaller width than the single pipe S1 (FIG. 33), the gap between the wood S2 and the hook-like portion 541 is reduced, and the hook-like portion 541 is stably provided. Can be hooked on the wood S2. Therefore, if the width of the non-holding member is at least a width that can be hooked by the hook-like portion 541 by bending the curved portion 541B, the hook portion 504 can be stably hooked in any width of the locked member. Thus, the electric driver 501 can be latched stably.

  Next, a power tool according to a seventh embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 35, in the seventh embodiment, an electric driver 601 will be described as a power tool. The electric driver 601 according to the seventh embodiment has substantially the same characteristics as the impact driver 101 according to the second embodiment. In the impact driver 101, the shaft portion 145 has the output shaft direction and the handle 103. Although arranged so as to be substantially orthogonal to the extending direction, in the electric driver 601, a shaft portion 645 (FIG. 37) described later is extended so as to obliquely intersect the output shaft direction and the extending direction of the handle 603. Yes. Therefore, about a main structure and structures other than the characteristic point of invention, 500 is added to the code | symbol which concerns on the impact driver 101 which concerns on 2nd embodiment, and the description is abbreviate | omitted.

  An electric driver 601 shown in FIG. 35 mainly includes a main body portion 602, a handle 603, and a hook portion 604. The main body 602 incorporates a motor (not shown) that is an output unit, and a chuck 621 that is an output shaft that rotates by being driven by a motor (not shown) is provided at the tip of the main body 602. The rotation axis of the chuck 621 is parallel to the output shaft direction, which is a direction from the main body 602 toward the chuck 621.

  A handle 603 serving as a grip portion extends from a side surface portion of the main body 602 in a direction intersecting with the output shaft direction. The handle 603 is provided with a power cord 605 for supplying power to a motor (not shown) at the distal end of the extension, and has a trigger 632 at the proximal end of the extension, and is not shown by the trigger 632. Motor drive control is performed.

  As shown in FIG. 36, the hook portion 604 includes a rotation support portion 631 provided at the front end of the handle 603 in the extending direction, a shaft support portion 641 supported by the rotation support portion 631, and an end of the shaft support portion 641. It is mainly comprised from the arm part structure part 644 provided in a part. The shaft support portion 641 is mainly composed of a rotating shaft portion 642 and a receiving portion 643. Since the configuration relating to the connection between the rotation support portion 631 and the receiving portion 643 is the same as that of the impact driver 101 according to the second embodiment, the description thereof is omitted.

  As shown in FIG. 37, the receiving portion 643 is formed with a hole 643a from the end on the counter-rotating shaft portion 642 side toward the rotating shaft portion 642, and a shaft portion 645 described later is inserted into the hole 643a. It is possible. Further, the hole 643a is formed so that the drilling direction does not coincide with the axial direction of the rotation shaft portion 642 and intersects obliquely. The rotation shaft portion 642 is supported by the rotation support portion 631 (FIG. 36) so that the shaft is substantially orthogonal to the output shaft direction of the electric driver 601 and the extending direction of the handle 603. Therefore, the hole 643a is configured such that the drilling direction obliquely intersects the output shaft direction of the electric driver 601 and the extending direction of the handle 603 in a state where the shaft support portion 641 is mounted on the rotation support portion 631. .

  A wall defining the hole 643a of the receiving portion 643 is provided with a notch 643A that is a latching portion. The notch 643A includes a claw 643B, and the claw 643B protrudes into the hole 643a. A spring 643D as an urging member is interposed between the notch 643A and the wall defining the hole 643a. The notch 643A is urged by the spring 643D, and the claw 643B always protrudes into the hole 643a. . Further, when the notch 643A is pushed against the spring 643D, the claw 643B can move from a state of protruding into the hole 643a to a state of being retracted. The wall surface of the receiving portion 643 that is near the opening and the inner surface of the hole 643a is provided with a retaining member 643C that protrudes toward the center in the diameter direction of the hole 643a and prevents a shaft portion 645, which will be described later, from coming out of the receiving portion 643. .

  The arm portion constituting portion 644 is mainly composed of a shaft portion 645 and an arm portion 646. The shaft portion 645 has a substantially cylindrical shape that is slidable by being inserted into the hole 643a, and includes an arm portion 646 at one end that is the rear end in the insertion direction of the hole 643a. Further, on the side surface of the shaft portion 645, a plurality of first recessed portions 645a and second recessed portions 645b, which are a plurality of hooked portions that are arranged from one end side to the other end side, are formed. Each of the first recess 645a and the second recess 645b can be engaged with the claw 643B. Further, the other end of the shaft portion 645 is provided with a protruding portion 645A that protrudes outward in the diameter direction from the side surface. The protruding portion 645A is configured to be able to come into contact with the retaining member 643C when the shaft portion 645 slides in the hole 643a.

  The arm portion 646 is integrally formed with the shaft portion 645 from an elastic material such as resin. The arm 646 extends from the shaft 645 so that the arm driver 601 outputs the output of the electric driver 601 with the arm component 644 mounted on the shaft support 641 and the shaft support 641 mounted on the rotation support 631. It is configured to be parallel to a plane defined from the axial direction and the extending direction of the handle 603.

  When working with the electric driver 601 having the above-described configuration, the arm portion 646 is disposed so as to be substantially parallel to the axial direction of the main body portion 602, and the claw 643B is hooked on the first recess 645a. As a result, the arm portion 646 is disposed in the vicinity of the surface of the handle 603, and the work is prevented from being hindered.

  When the operation is interrupted and the electric driver 601 is hooked on a thick member such as a single tube, as shown in FIG. 38, the notch 643A is pushed to disengage the claw 643B from the first recess 645a. Then, the arm portion constituting portion 644 is pulled and moved to a position where the claw portion 643B and the second recessed portion 645b can be engaged with each other. At this position, pressing of the notch 643A is stopped, and the claw portion 643B and the second recess 645b are engaged. As a result, as shown in FIG. 39, the arm portion constituting portion 644 including the shaft portion 645 is fixed to the shaft support portion 641 in a state where the arm portion 646 and the handle 603 are expanded, and is hooked on the single tube S. It becomes possible. In addition, since the arm portion 646 is made of an elastic material, even if the diameter of the single tube S is larger than the distance between the arm portion 646 and the handle 603, the arm portion 646 can be held to a certain extent. it can.

  As shown in FIG. 40, when the electric driver 601 is hooked on the thin pipe S ′ or the square member S ″ with the arm portion 646 expanded, the shaft portion 645 and the shaft portion 645 are received and supported. Since the receiving portion 643 is configured such that its axial direction is oblique to the axial direction of the rotating shaft portion 642, the pipe S ′ and the square material S ″ are the surface of the handle 603 and the receiving portion 643 extends. Located near the exit. Therefore, when the electric screwdriver 601 is hooked on the pipe S ′ or the square member S ″ that are thin hook members, the handle 603 is connected to the pipe without reducing the distance between the arm portion 646 and the handle 603. It can be hooked in the vicinity of S ′ or square material S ″, and the electric driver 601 can be hooked stably.

  As shown in FIG. 38, when the angle between the center axis of the rotation shaft portion 642 and the center axis of the hole 643a is θ, the distance along the center axis of the rotation shaft portion 642 of the hole 643a is L Then, the distance L ′ = L / cos θ along the central axis of the hole 643a is obtained. In this relationship, the center axis of the hole 643a is more in the case of 90 °> θ> 0 ° than in the case where the center axis of the hole 643a where θ = 0 ° coincides with the center axis of the rotation shaft portion 642. The distance along can be increased. By increasing the distance along the central axis of the hole 643a, the distance inserted into the hole 643a of the shaft portion 645 is increased, and the fitting portion can be taken longer. Therefore, by taking a long fitting portion, even if the shakiness of the shaft portion 645 held by the receiving portion 643 is reduced and the width between the arm portion 646 and the handle 603 is widened, the receiving portion 643 is surely received. Thus, the shaft portion 645 can be held.

  Further, as the shape of the hook portion 604, the sliding direction of the shaft portion 645 is added to the rotation shaft portion 642 by an angle θ, so that the sliding direction of the shaft portion 645 is the same as the axial direction of the rotation shaft portion 642. Compared to the case, the possibility that the hook portion 604 interferes with a non-locking member, an obstacle or the like is reduced in the range shown in the region C (shaded portion) shown in FIG. Can be improved.

  The electric screwdriver 601 that is a power tool according to the seventh embodiment has a shape including a plurality of hooked portions, but is not limited thereto, and conversely includes a plurality of hooking portions. The hooked portion may be hooked on the portion, and the extension amount of the shaft portion from the shaft support portion may be defined.

  As a modification, as shown in FIGS. 42 to 44, a configuration including a pair of a hooking portion and a hooked portion may be adopted. In this configuration, a notch 643A in which a claw 643B protrudes in the hole 643a is provided in the vicinity of the connection position of the receiving portion 643 with the rotating shaft portion 642. On the wall surface of the receiving portion 643 that is near the opening and the inner surface of the hole 643a, a retaining member 643C that protrudes toward the center in the diameter direction of the hole 643a is provided. The shaft portion 645 has an arm portion 646 at one end and a hooked portion 645B at the other end of the shaft portion 645. As shown in FIG. 43, the other end of the shaft portion 645 is provided with a protruding portion 645A that protrudes outward in the diameter direction from the side surface thereof and can come into contact with the retaining member 643C. In the hole 643a, a spring 647 is provided between the shaft portion 645 and the receiving portion 643 to bias the shaft portion 645 toward the counter-rotating shaft portion 642.

  In this configuration, the arm portion constituting portion 644 including the arm portion 646 includes a state in which the claw 643B and the hooked portion 645B shown in FIG. 42 are hooked, and a claw 643B and the hooked portion 645B shown in FIG. And the dissociated state can be taken. When the claw 643B and the hooked portion 645B are hooked, the arm portion 646 is located near the handle (not shown), and when the claw 643B and the hooked portion 645B are dissociated, the shaft portion 645 is moved by the spring 647. Therefore, the arm portion 646 is separated from a handle (not shown). Therefore, even in a configuration including a pair of the hooking portion and the hooking portion, the arm portion can take two positions, a position close to the handle that is the gripping portion and a position separated from the handle. Accordingly, the arm portion can be arranged at an appropriate position.

  Further, an anti-slip member such as an elastomer may be disposed at a position where the arm portion comes into contact with the hooked member. As a result, friction is generated between the member to be hooked and the arm portion, so that the power tool can be hooked more stably.

  The present invention is a power tool that is driven by electricity, compressed air, fuel, or the like, and can be generally applied to a power tool that is gripped and operated by a user.
