[0010] Preferably, the outer surface of the connecting rod is located inside the fixed frame, and the thickness of the upper and lower ends of the connecting rod is less than the distance between the upper and lower ends of the inner wall of the fixed frame.

[0011] Preferably, the rack plate is movably arranged close to the outer surface of the gear, and the rack plate and the gear are meshed with each other.

[0012] To sum up, the present application has the following beneficial technical effects:
