The front and rear ends of the spring 8 are welded to the rectangular slide 31 and the positioning base 1 respectively.

[0022] Working principle: When the present invention is used, the user pushes the pressing pin 35 backward, and the pressing pin 35 drives the rectangular slide 31 to move backward, so that the multiple movable splints 32 move backward at the same time, and compresses the spring 8 at the same time.
