[0017] In a possible design, a positioning groove is provided at the bottom of the clamping plate, and the positioning groove cooperates with the insertion rod.

The horizontal plate pushes the two round rods away from each other, and one end of the two horizontal plates is inserted into the inside of the clamping slot to fix the position of the handle to prevent the handle from being accidentally touched. The fixing rod gradually moves out of the inside of the slide slot, and the tension spring is stretched, which can facilitate the retraction of the round rod.
