It will be described based on. FIG. 1 shows an entire portable tool 10 to which a hook 1 according to the present embodiment is attached. The housing of the portable tool 10 is composed of a front housing 11 on the front end side (left side in the drawing) from the center and a rear housing 12 connected to the rear of the front housing 11. The rear housing 12 is further divided vertically. The portable tool 10 has three housings 11, 12a, and 12b in total (see FIG. 2).

The front housing 11 is formed in a substantially cylindrical shape, and a drive motor and a gear train for transmitting the rotational force of the drive motor are incorporated in the inside of the front housing 11, although not shown. Also, the rear housing 12a,
Reference numeral 12b is overlapped with the rear portion of the front housing 11 sandwiched therebetween, and is fixed by screws 13 to 13.

An annular edge 11a is integrally formed on the rear end face (right end face in the figure) of the front housing 11 so as to surround the drive motor. This ring 1
Reference numeral 1a denotes a portion having a function as a connection margin for connecting the rear housing 12, and the two housings 11, 12 are connected with the annular edge 11a inserted into the inner peripheral side of the rear housing 12. . That is, a groove portion 11b is formed on the entire outer peripheral surface of the annular edge 11a, and a ridge 12c formed on the inner peripheral surface of the rear housing 12 is fitted into the groove portion 11b, and The two housings 11 and 12 are connected in a state where the rear housing 12 is prevented from falling out.

The hook 1 of this embodiment is provided at the connection between the front housing 11 and the rear housing 12 formed as described above.
Is incorporated. As shown in FIG. 3, the hook 1 is formed by integrally forming a support portion 2 having an annular shape and a hooking piece 3 bent substantially in an L-shape. ing. The support portion 2 is provided with the ring edge 11
a having an inner diameter capable of slidingly contacting the outer peripheral surface of a. Further, a plurality of locking grooves 2a to 2a are formed in the support portion 2 at predetermined intervals in a circumferential direction thereof, and the locking grooves 2a to 2a are engaged with a leaf spring 5 as a holding portion described later. It is a stop.

As shown in FIG. 2, the supporting portion 2 formed as described above is provided with an annular edge 11a of the front housing 11.
And is rotatably supported around the axis of the front housing 11. Then, as shown in FIG. 1, the hook pieces 3 protrude from a circumferential gap formed between the front housing 11 and the rear housing 12, and are directed toward the tip end of the tool 10. . Therefore, the hook 3 can be translated around the outer periphery of the tool 1 in a state where the hook 3 is directed toward the distal end along the axial direction of the tool 1.

Next, the above-mentioned holding portion is the rear housing 1.
2 is provided. That is, as shown in FIG. 2, projecting edges 12d and 12e are formed on the inner peripheral surfaces of the left rear housing 12a and the right rear housing 12b, each of which is vertically divided into two, and project from each other. The two protruding edges 12d, 12e
Is provided so as to protrude above the locking groove 2 a of the hook 1. Then, the both protruding edges 12d,
The leaf spring 5 as the above-mentioned holding portion is attached in a bridging manner between the portions 12e. The leaf spring 5 is formed by bending a strip-shaped small piece having elasticity substantially downward in a substantially central shape at the center thereof, and the bent distal end portion (the central portion of the leaf spring 5) is hooked. Are elastically pressed against the peripheral surface of the support portion 2.

According to the hook 1 of the first embodiment configured as described above, the support 2 on which the hook 3 is integrally formed.
Is rotatably supported by an annular edge 11a of the front housing 11. As a result, the hook piece 3 moves in the axial direction of the front housing 11 (that is, in the axial direction of the tool 10).
The tool 10 can be translated around the outer periphery of the tool 10 in a state where the tool 10 is turned forward.

On the other hand, a leaf spring 5 is mounted on the rear housing 12, and a central portion (a bent end portion) of the leaf spring 5 is elastically pressed against the peripheral surface of the support 2. A large number of locking grooves 2a are formed on the peripheral surface of the support portion 2. Therefore, when the support portion 2 rotates, the bent distal end portion of the leaf spring 5 rides on the peripheral surface of the support portion 2 and is elastically pressed into contact with the locking groove 2a to prevent the rotation of the support portion 2. Two states are realized. That is, when the bent distal end portion of the leaf spring 5 is fitted into the locking groove 2a, the rotation of the support portion 2 is prevented, and the hook piece 3 is held at a certain position. If a force exceeding the elastic force of the leaf spring 5 is applied to the hook 3 from this state, the hook 3 can be translated around the outer periphery of the tool 1.

Thus, the hook pieces 3 can be used as the hooks 1 by holding the hooks 3 at the positions corresponding to the number of the locking grooves 2a formed in the support portion 2.

Here, as shown in FIG. 3, the locking groove 2a is formed over the entire circumference of the support portion 2. Therefore, by providing a gap between the front housing 11 and the rear housing 12 (a gap where the hook pieces 3 protrude) over the entire circumference of the tool 1, the hook pieces 3 are formed around the entire circumference of the tool 1. And can be used as the hook 1 by holding the position at an appropriate position over the entire circumference.

It should be noted that the gap is not provided on the entire circumference as described above, but, for example, only in the range of high use frequency.
In the case where it is sufficient to make it possible to move, a gap is provided in a range of, for example, about 270 ° in the upper side in FIG. 2, and the locking groove 2a is formed only in a range corresponding to this range. It is also possible to use the hook 1 at an appropriate position.

As described above, according to the hook 1 of the first embodiment, the hook 3 can be moved around the outer periphery of the tool 1 and the hook 1 can be used at many positions around the outer periphery. . Therefore, the tool 1 can be hung on a belt or the like in a stable state by moving and using the hook piece 3 at an optimum position with respect to the shape of the tool 1. In addition, the hook 1 can be easily used by moving the hook 3 from the left side to the right side of the tool 1 depending on whether the worker is right-handed or left-handed. By moving the hook 3 together, the hook 1 can be used conveniently and in a state where its function can be sufficiently exhibited.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, a modification example of the locking portion and the holding portion will be described. Others are the same as in the first embodiment. As shown in FIG. 4, the hook 20 of the second embodiment is different from the hook groove 2 of the first embodiment.
Lock holes 21a to 21a are provided instead of a. The locking holes 21a are formed in the flange 21b of the support 21 corresponding to the support 2 in the first embodiment at appropriate intervals in the circumferential direction. The hook piece 22 is the same as that of the first embodiment, is bent substantially in an L shape, and is formed integrally with the support portion 21.

On the other hand, instead of the leaf spring 5, the holding portion is configured to hold the position of the hook piece 22 by inserting a locking pin 25 into the locking hole 21a. That is, as shown in FIG. 5, the holding portion of the present example has a plate-shaped lock knob 26 supported on the upper end of the rear housing 31 so as to be slidable in the front-rear direction (left-right direction in the drawing). The support rod 26a is integrally formed in a state protruding downward,
The locking pin 25 is orthogonally attached to the tip of the support rod 26a. A compression coil spring 27 is mounted between the support rod 26a and the wall 31a of the rear housing 31, and the locking pin 25 is pressed against the flange 21b of the support 21 by the compression coil spring 27. ing.

According to the above configuration, when the lock knob 26 is slid backward (to the right in the drawing), the locking pin 25 also moves in the same direction and is pulled out from the locking hole 21a, whereby the support 21 is Ring 30a of front housing 30
, So that the hook piece 22 can be translated around the outer periphery of the tool. On the other hand, the lock knob 26
Is moved forward (leftward in the figure) by the urging force of the compression coil spring 27, the locking pin 25 also moves in the same direction and is pressed against the flange portion 21b. When the hook 22 is moved and the support 21 is rotated in this state, the locking pin 25 relatively moves while being pressed against the flange 21b, and finally fits into the locking hole 21a. Get stuck. When the locking pin 25 is fitted into the locking hole 21a, the movement of the support portion 21 and thus the hook piece 22 is prevented, and the hook piece 22 can be used as the hook 20 at this position.

As described above, also according to the configuration of the second embodiment, the hook piece 22 can be moved around the outer circumference of the tool.
And it is designed to be fixed at many positions in this movable range. Therefore, as described above, the hook 20 can be used more effectively than before by selecting the position of the hook piece 22 according to various situations.

According to the structure of the second embodiment, when the position of the hook 22 is changed, the position of the lock knob 2 is changed.
6 is required to move backward and hold, and the operation to move the hook 22 is required.
There is an advantage that the position of the hook piece 22 can be more firmly held than in the configuration of the embodiment.

Further, in the illustrated two embodiments, the support portion 2 (21) having an annular shape is exemplified, but the shape of the support portion is not limited to this, and may be, for example, a C-shape or an arc shape. An embodiment support is conceivable. In short, the support portion supports the hook piece 3 (22) so as to be able to move parallel to the axis of the tool body 10 and can hold the hook piece 3 (22) at a plurality of positions in the circumferential direction. Therefore, the usability can be remarkably improved as compared with the conventional hook.
