The servo motor 7 is in shaft connection with the screw rod 8, and the bottom end of the screw rod 8 is connected to the bottom plate 4. Since the motor screw rod lifting mode is a mature technology, the details are not repeated here.
In this embodiment, the number of the piston driving mechanisms is two, and the piston driving mechanisms are both arranged on the lifting bracket 6. The lifting support 6 comprises a transverse support 61 and two vertical supports 62, and the vertical supports 62 are connected with the lifting slide rail 15 in an adaptive manner.
