The block 22 is fixedly connected to the connecting body 10, and the block 22 can be inserted into the rectangular groove of the first limiting body 20 and the second limiting body 21. When the end faces of the first limiting body 20 and the second limiting body 21 conflict with each other, the distance between the side walls of the first limiting body 20 and the second limiting body 21 is less than the distance between the two blocks 22.
