[0018] The method of using the utility model is as follows: When the positioning plug 25 of the push-pull rod 2 needs to be inserted into the connecting hole of the product (such as a plastic part of an automobile), refer to Figure 4 First, push the push-pull rod 2 to slide forward along the slide groove 11, so that the positioning plug 25 of the push-pull rod 2 is inserted forward into the connecting hole of the product to position the product. During this process, the rod portion 41 of the locking rod 4 can move backward relative to the long through hole 23 to the position of the locking interface 24, and then move the locking rod 4 outward for a distance, and the locking portion 42 of the locking rod 4 is inserted into the locking interface 24. The locking portion 42 locks the push-pull rod 2, so that the push-pull rod 2 cannot slide, so that the positioning plug 25 of the push-pull rod 2 always maintains the state of positioning the product; when the positioning plug 25 of the push-pull rod needs to be removed from the connecting hole of the product (such as a plastic part of an automobile), refer to Figure 5First, move the lock rod 4 inward for a distance, the locking portion 42 of the lock rod 4 is separated from the lock interface 24 and inserted into the countersunk hole 12, and then pull the push-pull rod 2 backward, the push-pull rod 2 can slide backward along the slide groove 11, and then the positioning plug 25 of the push-pull rod is moved out of the connecting hole of the product (such as a plastic part of an automobile). It can be seen that the utility model can make the push-pull rod 2 extend forward and be locked by the lock rod 4 to position the product, or make the lock rod 4 release the lock on the push-pull rod 2, so that the push-pull rod 2 moves backward to release the positioning of the product, and the whole process is completed manually, without the need for a cylinder and an air compressor, with low overall cost, simple structure, convenient installation, and small space occupation.
