When the output end of the first motor 2 drives the screw rod 301 to rotate, the screw rod 301 drives the threaded ring 302 to transmit the transmission, and the threaded ring 302 drives the connecting block 303 to transmit the transmission. Because the connecting block 303 is restricted on the first slide bar 305 by the slip ring 304, the screw rod 301 drives the threaded ring 302 to move vertically, and the threaded ring 302 drives the connecting block 303 to move vertically, and the connecting block 303 drives the slip ring 304 to move vertically, so that the electric telescopic rod 4 is driven to move vertically through the connecting block 303, and then the fixed seat 703 is driven to move to the height of the unfinished mechanical parts.
