[0002]
[Prior art]
For example, when wiring a wire harness to the body of an automobile, a clip as shown in FIG. 1 is used. The clip 1 includes an annular holding portion 2 that holds a wire harness, and a locking portion 3 that is fastened to a through hole 8 a provided in a plate material such as a frame 8. The locking portion 3 is opened and closed on the side surface of the body portion 4, the hollow body portion 4, the elastic pressing portions 5 and 5 that are formed to protrude laterally between the holding portion 2 and the body portion 4. It consists of freely formed locking claws 6 and 6. When the wire harness is held by the holding portion 2 and the barrel portion 4 is pushed into the through-hole 8a of the frame 8, the locking claws 6 and 6 are pushed into the barrel portion 4 against the elastic force and locked. When the claws 6 and 6 are pulled out to the opposite side of the through hole 8a, the locking claws 6 and 6 open in the direction of expanding the diameter by the elastic force, and are engaged with the peripheral edge of the opening end of the through hole 8a. , 5 to fix the body 4 to the frame 8. In this way, the wire harness is fixed to the frame.
[0003]
[Problems to be solved by the invention]
By the way, the wire harness fixed to the frame may be removed due to maintenance or the like. In such a case, it is necessary to remove the clip 1 from the frame 8. The clip 8 is removed by an operator with a bare hand or using a tool such as a pliers or a screwdriver.
[0004]
In the case of performing with bare hands, the locking claws 6 and 6 are pushed into the body part 4 with the fingertips and closed. However, since the latching claws 6 and 6 are relatively small, it is difficult to push the clip 1 into the body 4 with a fingertip, and it is difficult to remove the clip 1. Also, you may get hurt.
When a tool such as a pliers is used, the locking claws 6 and 6 are sandwiched and pushed into the body part 4, and in this state, the body part 4 is pulled out from the through hole 8a. In this case, the clip 1 can be easily removed as compared with the case of performing with bare hands. However, the location where the clip 1 is fixed, particularly the frame of an automobile, often has a narrow space on the side from which the locking portion 3 protrudes, and it may be difficult to use a tool such as a plier. When the tool cannot be used in this way, the clip itself is broken and removed. Therefore, the broken clip is discarded because it cannot be reused.
[0005]
An object of the present invention is to provide a clip removing jig that can solve the above-described problem when removing a clip and can be easily removed from a plate material to which the clip is fixed.
[0006]
