when the negative pressure is generated by the negative pressure seat 18, the elastic adsorption ring 24 clings to the bottom surface and deforms itself, so that gaps are reduced, and the negative pressure can stably adsorb the bottom surface.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
