【Example】

(Embodiment 1) An example of holding the pliers A using the auxiliary grip of the present invention will be described with reference to FIG. First, the manipulator hand M will be described. As shown in FIG. 3A, both holding surfaces M1 can be opened and closed in a parallel state to hold the holding surface M1, and a rib perpendicular to the holding surface M1 formed thin toward the tip end. M2 is provided. Further, notches M3 each having a substantially rectangular parallelepiped shape were formed on both sides of the holding surface as shown in FIG. As described later, the hole is formed by facing the notch of the base 1, and the auxiliary grip is prevented from falling off when the tip of the wing bolt 4 is inserted into the hole.

The auxiliary grip of the present invention is, for example, fitted to the hand M from which the rib M2 protrudes, and includes the base 1 and the fixing plate 5. First, as shown in FIG. 3, the base 1 has a concave portion 2 having a concave portion 2 adapted to the manipulator holding surface M1.
1A is formed by screwing two base lids 1B with an interval 3 corresponding to the thickness of the rib M2.

Further, bolt holes 7 are formed at both sides of the base 1A at positions corresponding to the cutouts M3 when the base 1 is fitted into the hand, and the base 1 is fixed to the manipulator hand as shown in FIG. This is performed by screwing a wing bolt 4 into the bolt hole 7. Here, the center of the bolt hole 7 is exactly the concave portion 2.
The recess 2 has a semi-cylindrical notch 8 continuous with the bolt hole 7.

When the base 1 is fitted from the tip of the manipulator hand, the rib M2 corresponds to the interval 3 (FIG. 1B),
The holding surface M1 is in contact with the surface of the concave portion 2, and at this time, the notch M3 of the holding surface and the notch 8 of the concave portion 2 also face each other. Then, when the wing bolt 4 is screwed into the bolt hole 7 of the base, the tip of the bolt reaches the hole formed by the two cutouts M3 and 8, thereby preventing the base 1 from coming off. Even when the notches 8 and M3 are not formed, the auxiliary grip can be fixed to the hand by pressing the side of the hand holding surface with the tip of the bolt.

On the other hand, the fixing plate 5 is for holding a handle A1 such as pliers between the fixing plate 5 and the base 1, and can be mounted on the base 1 by screwing screws 6 into holes formed in four corners. When attaching the pliers, the four screws are loosened to widen the space between the base 1 and the fixing plate 5, the handle A1 is inserted there, and the screws 6 are tightened and fixed again.

As shown in FIG. 6, grooves 9 and 10 are formed on the opposing surfaces of the base 1A and the fixing plate 5, respectively, so as to easily hold the handle A1 of the tool. Various fixing plates may be prepared according to the size and the like. In this example, as shown in FIG. 1A, since the nose pliers A which can be always held open by the spring A2 was used, only the handle A1 on one side was fixed by the auxiliary grip. In use, the handle A1 of the tool is sandwiched by the manipulator hand M, and the pliers A are opened and closed. In this example, the radio pliers have been described as an example. However, similarly, various tools such as nippers and bent-nose pliers can be held.

(Embodiment 2) Next, an example in which an insulator gripping tool is attached to a manipulator will be described with reference to FIG. As shown in FIG. 3A, arc-shaped claws B are attached to the distal ends of the manipulator hands M so as to easily grip the insulator. The base 1 inserted into the tip of the manipulator hand is substantially the same as that of the first embodiment, except that a shallow groove (not shown) into which the handle B1 of the claw is inserted is formed substantially at the center of the outer surface of the base 1A. Attachment holes are provided at four places with this groove interposed. On the other hand, the nail B itself is a plate-shaped one, but the handle B1 is a block-shaped one, and the nail B extends from the center thereof, and four nails are provided at positions corresponding to the mounting holes with the nail B interposed therebetween. A hole is formed. The nail B can be attached to the base 1 by passing the screw 6 through the through hole and screwing it into the mounting hole of the base. When using,
By opening and closing the manipulator hand, if the constricted portion of the insulator is sandwiched between the claws B, the insulator can be reliably held. The mechanism for fixing the base to the tip of the manipulator hand is the same as that in the first embodiment, and a description thereof will be omitted.

(Embodiment 3) In the above example, a wing bolt was used for fixing the auxiliary grip.
In the embodiment described below, a wing bolt is not used, and a mounting pin 11 that can be fitted into and removed from the notch 8 and M3 with one touch is used.
As shown in FIG. 7 and FIG.
Comprising a 1A and the base lid 1B, the base bottom portion 1A, (see FIG. 8) to notch 8 corresponding to the notches M3 of the hand holding surface is the same as the first embodiment in that is formed. On the other hand, in the present embodiment, the swing lever holding portions 12 are provided on both sides of the base body, and the fool holes 13A (bolt holes 7 in the first embodiment) formed in the notches 8 are formed.

The swing lever holding portion 12 is a block-like member having an upper portion formed in a stepped shape of an upper stage and a lower stage. An elongated hole 14 is formed in this lower stage surface, and a mounting pin is provided on a joint surface with the base 1. Eleven through holes 13B are formed. The elongated hole 14 is formed only deep at one end to form a spring holding hole 14A, and the shallow portion forms a shaft support hole 14B of the swing lever (FIG. 7).
B). The through hole 13B is located on the other end side of the elongated hole 14, and when the swing lever holding portion 12 is attached to the base 1 with the bolt 15, the through hole 13B The holding hole 13 (see FIG. 7A) is formed. The holding hole 13 is formed such that the inside diameter is large (large diameter portion) and the diameter at both ends is small (small diameter portion).

On the other hand, the mounting pin 11 has an engagement portion 16 having a large diameter substantially in the middle, and the outer diameter of the engagement portion 16 corresponds to the large-diameter portion of the mounting pin holding hole 13. The diameter of the pin corresponds to the small diameter portion. The mounting pin 11 has a compression spring
One end presses the boundary between the large-diameter portion and the small-diameter portion in the base hole 13A, and the other end presses the engaging portion 16, so that the mounting pin 11 is always fitted into the notch 8, M3. Not configured. Further, as shown in FIG. 7B, the swing lever 18 is of a T-shape having a leg portion 18B at the center of the top plate 18A, and the leg portion 18B is swingable through a lever shaft support hole 14B. One end of the top plate 18A is pressed by a spring 19 inserted into the spring holding hole 14A. By this pressing, the other end of the swing lever 18 presses the mounting pin 11 with the engaging pin 20 protruding from the lower surface of the top plate, but the mounting pin 11 is in a state where it is not normally fitted into the notch 8, M3. In this case, the tip of the engagement pin 20 is in a state of riding on the engagement portion 16 of the mounting pin.
Then, similarly to the first and second embodiments, the fixing plate and the handle can be attached to the base 1A.

The auxiliary grip having such a configuration is fitted to the manipulator hand, the mounting pin 11 is pushed in, and its tip is fitted to the notch 8, M3. At this time, as shown in FIG. 8, since the engaging portion 16 of the mounting pin moves in the direction of the base,
The engaging pin 20 is disengaged from the engaging portion 16 and descends to the mounting pin 11 other than the engaging portion. As a result, the engaging pin 20 comes into contact with the engaging portion 16 of the mounting pin which is going to return due to the repulsion of the spring 17, and the tip of the mounting pin 11 is held in a state fitted in the notch 8, M3. When removing the auxiliary grip, the engaging pin 20 is flipped up by pushing one end of the swing lever top plate 18A, thereby releasing the engagement between the engaging pin 20 and the engaging portion 16 and the elasticity of the spring 17 The mounting pin is notched by 8,
Return to a state where it does not fit into M3.

As described above, according to the auxiliary grip of the present embodiment, the mounting to the manipulator hand can be easily performed by one-touch operation of the mounting pin or the swinging lever, and the screwing work of the wing bolt as in the first and second embodiments can be performed. It is very convenient because it is not required. Needless to say, this mounting work can be performed manually by an operator.However, since the operation of fitting and removing the mounting pin into and out of the notch is a pushing operation, the auxiliary grip must be mounted on one hand with the other hand. Can also be easily done. In other words, when the pulling or rotating operation is required for the fitting / unmoving operation, it is difficult to operate the hand with the optimal force for this operation. On the other hand, in the pushing operation, the manipulator hand is simply attached to the mounting pin or the swing lever. It is only necessary to hit

[0016]

As described above, according to the tool of the present invention, tools such as pliers and nippers can be firmly held by the manipulator and used easily. In addition, a notch is provided between the hand holding surface and the concave portion of the base, and a bolt or a mounting pin is fitted into the notch, so that the auxiliary grip can be reliably prevented from falling off. In particular, an auxiliary grip that uses an attachment pin and engages and disengages with the notch in cooperation with the swing lever is extremely convenient because it can be attached to and detached from the manipulator hand by one-touch operation.
