FIG. 1 is an exploded perspective view showing the entire operation tool of the present invention. In the figure, (11) is a wrench head composed of a pair of jaw members (12) and (13) rotatably connected to each other, which utilizes a conventionally known wrench head portion. Usually, the jaw member (12) on the rotating side is fixed to the jaw member (13) on the fixed side by a leaf spring (14).
Always the tooth-shaped biting surface of these jaw members (12) (13) (15)
(15) is urged in the direction to approach. The method of urging the spring (14) in this case is well known, and a detailed structure thereof will be omitted.

The base end of the fixed-side jaw member (13) opposite to the biting surfaces (15) and (15) has a pipe-shaped operating rod (16).
Is rotatably pivoted to the tip of the device by a pin (17). That is, the distal end of the operation rod (16) is formed with a slit (18) over a predetermined length from the distal end face, and the base end of the jaw member (13) is inserted into the slit (18). It is pivotally supported by a pin (17) inserted from the side of the operating rod (16). An operation wire (20) is connected once to the back side of the other rotating side jaw member (12), and the other end of the operation wire (20) is
The operation rod (16) is drawn into the operation rod (16) through a communication hole (21) formed near the tip of the operation rod (16). On the other hand,
At the position near the base end of the operating rod (16),
6) A long guide hole (22) in the longitudinal direction is formed in the longitudinal direction, and a cylindrical jaw opening / closing member (24) is extended in the longitudinal direction so as to cover the guide hole (22). And FIG.
Are slidably fitted outside as shown by. An end of the wire (20) inside the operation rod (16) is connected to a jaw opening / closing member (24) by a fastening bolt (25) and a nut (26) penetrating the guide hole (22). I have. Further, a rubber cylindrical cover (27) is fitted on the outer peripheral surface of the jaw opening / closing member (24).

[0010] That is, the jaw closing member (24) is slidable range fastening bolt (25) can be moved by the guide hole (22) within the jaw closing member (24) as shown in Figure 2 When the operation bar (16) is slid toward the base end side, the rotation side jaw member (12) is rotated so as to open via the wire (20). A holding member (28) for the wire (20) is attached to the tip of the operating rod (16) using a pin (17) for pivotally connecting the fixed-side jaw member (13).

An L-shaped gripping member (30) is attached to the proximal end of the operating rod (16) to form an L-shaped grip (31). The grip (31) is made of rubber or other cylindrical coating material (3
Covered by 2).

Next, a method of rotating a bolt or other members using the operating tool will be described. First, as shown in FIG. 4A, hold the grip portion (31) with one hand, hold the chin opening / closing member (24) with the other hand, and move the chin opening / closing member (24) toward the front. (Rightward in the figure), the rotating jaw member (12) opens via the wire (20).
In this state, the bite surface (15)
When (15) is positioned to by releasing the jaw closing member (24), with the jaw <br/> closing member (24) is pulled by the wire (20), rotating-side jaw member by the force of the spring (14) (12) rotates to the original side and is locked with the bolt (33) bitten. At this time, the wrench head (11) is held so as to project in a direction substantially perpendicular to the operating rod (16).

When the operating rod (16) is pulled toward the user from the above state as shown in FIG. (B), the wrench head (11) rotates in the direction of the arrow in the figure around the pin (17). This causes the bolt (33) to be rotated in the same direction.

Next, when the operating rod (16) is moved in the pushing direction, the wrench head (11) also rotates in the original direction. At this time, as a known wrench structure,
When rotated in the opposite direction, the bolt (33) is unlocked and slid, and when rotated in the same direction as (B) from this state, the bolt (3) is again rotated.
2) Can be rotated while locked. Then, while repeating this, the bolt (33) can be rotated clockwise in the figure. When the bolt (33) is rotated in the opposite direction, the wrench can be operated by pushing and pulling the operating rod (16) by locking the wrench head (11) from the opposite side.

When it is necessary to rotate the lock nut or the like promptly, as shown in FIG.
By pressing the outer peripheral surface of the coating material (32) of 1) against the outer surface of the nut (35) and moving it in the horizontal direction,
Can be operated.

The above operating tool can be used not only for bolts and nuts but also for rotating pipes and the like.
