[0135] When the mounting plate assembly 101 reciprocates along the vertical direction relative to the frame 114, the linear rail 113 reciprocates along the vertical direction relative to the sliding block 111 fixedly installed on the frame 114.

[0136] In some embodiments, the lifting driving pair can also be realized by a combination of a chain wheel and chain, a synchronous belt and a pulley, and a hydraulic cylinder, a motor, etc.
