[0010] As a preferred solution, a bearing plate for stabilizing the rotation of the transmission rod is fixedly mounted on the inner wall of the inner cavity close to the knob, and the transmission rod is inserted through the front side of the bearing plate.

[0011] As a preferred solution, patterns for increasing friction are evenly arranged on the outer wall of the knob.

[0012] As a preferred solution, a sliding groove for limiting the rotation of the transmission rod is provided on the inner side of the hexagonal block, and the end of the transmission rod away from the rotating plate is slidably connected to the sliding groove through a slider.
