Referring to fig. 6, a support 8 is provided at the center of the lifting top plate 35, the support 8 includes a pair of position-limiting sleeves 80 capable of being aligned with the center of the upper end surface of the lifting top plate 35, the top surface of the position-limiting sleeves 80 is flush with the horizontal height from the concave surface of the transition connection bottom plate 73 to the low point, a buffer spring 81 is fixed in the position-limiting sleeves 80, and a central plate 82 is fixed above the buffer spring 81.

The center of gravity position of the bottom of the workpiece is firstly contacted with the central plate 82, the central plate 82 buffers pressure by pressing the buffer spring 81 downwards, after the buffer spring 81 deforms to a certain degree, the bottom of the workpiece is contacted with each excessive top plate 75, the phenomenon that the workpiece is damaged due to excessive pressure of the excessive top plate 75 at the edge caused by gravity center offset in the moment of placement can be avoided, the central plate 82 is a flexible plate, abrasion of the contact position of the head of the workpiece is avoided, the central plate 82 is pressed to move downwards for a certain distance and then abutted against the limiting sleeve 80, the limiting sleeve 80 supports the central plate 82 at the moment, the phenomenon that the buffer spring 81 is excessively pressed and cannot recover to deform is avoided, and meanwhile, damage caused by excessive pressure of the surrounding excessive top plate 75 is also avoided.

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 attributes 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.
