[0027] In a specific implementation manner, a slider 406 is arranged to slide in the slide groove 6, so that the slider 406 provides a better support effect on the plug-in board 404, and avoids the plug-in board 404 from being offset in the first plug-in groove 5, thereby causing a jam and affecting the use; and a connecting rod 402 is arranged to prevent the first spring 403 from bending when being compressed, thereby affecting the rebound effect of the first spring 403.
