after the clamping mechanism 5 moves to the outer surface of the heavy object, the driving gear 405 drives the rotating shaft 404 and the servo motor a403 to descend simultaneously through the cooperation of the spring groove 410 and the compression spring 411, so that the U-shaped movable table 401 descends at the bottom end of the fixed table 402, at this time, the connecting rod 409 is subjected to elastic potential energy of the compression spring 411, after the clamping mechanism 5 clamps the heavy object, the electric push rod 407 stops driving the push rod 408 to push downwards, and the connecting rod 409 can rebound due to the elastic potential energy to enable the driving gear 405 to return to the original position and mesh with the longitudinal toothed chain 202, so that the position of the lifting mechanism 3 can be adjusted only without adjusting the position of the clamping mechanism 5.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
