How to realize the lifting movement of the lifting frame, the invention adopts the lifting frame to be connected with a vertically arranged screw rod through a screw rod nut; and the motor drives the plurality of screw rods to synchronously rotate through the connection of the synchronizing shaft and the steering gear.

The lifting movement of the lifting frame drives the screw rod to rotate through the motor, so that the lifting of the screw rod nut on the screw rod is realized, and the lifting of the lifting frame on the screw rod is further realized; in the lifting process, only one motor is used, and the synchronous rotation of the plurality of screw rods is realized through the matching of the synchronizing shaft and the steering gear, so that the lifting frame is always in a horizontal state in the lifting process.
