Due to the characteristics of the shape of the inclined body 712 itself, the inclined body 712 pushes the roller 713 to move during the rotation process, and the roller 713 pushes the telescopic rod 715 to move through the adjustment frame 714, so that the adjustment frame 714 and the fixing ring 716 compress the spring 717.
