[0002] Clamps are commonly used components in mechanical production. Currently, there are multiple models of multi-curved manifold plates, all of which share a common characteristic: curved outer walls. Existing clamps utilize clamping blocks for clamping. However, due to the varying widths of the manifolds, clamping different models requires replacing clamps of varying sizes, making changeovers very time-consuming. Furthermore, clamping with the clamps requires manual operation, which can sometimes result in injuries.

[0003] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content
