Then the plug-in rod 21 will drive the reducing groove 25 opened on the side wall of the bottom end to rotate. Due to the special structural design of the reducing groove 25 and the limiting of the side wall of the limiting sleeve 24 on the side wall of the plug-in block 26, as well as the automatic reset characteristic of the push spring 28, while the reducing groove 25 rotates with the plug-in rod 21, the push spring 28 will slowly reset and push the plug-in block 26 to move. , so that one side of the plug-in block 26 gradually moves inward and always fits with the side wall of the reducing groove 25.
