Such as: flat-nose pliers, chucks, suction cups, disks, clamping blocks, etc., which generally satisfy the clamping requirements for the machining of most parts. However, when a part is machined, the clamping method also interferes with the machining process of the part, and the continuity of the machining process is affected. For example, when a large and not too thick plate workpiece is machined, clamping methods such as flat tongs, a chuck, a sucker and a magnetic disk are not suitable. The pressing plate is selected to tightly press and fix the plate workpiece on the workbench, and then the part is milled. The milling cutter is in the process of plane processing, the milling cutter must avoid the position of the pressing plate, so that the material below the position of the pressing plate cannot be milled, the processing is discontinuous and discontinuous, the pressing plate is used at the position changed after the first processing is finished, the part is clamped for the second time, and then the material of the interference part of the pressing plate is processed during the first processing. And when the workpiece is clamped by the pressing plate, the pressing plate can press the workpiece only by using the combination of the T-shaped bolt, the locking nut, the pressing plate, the cushion block and other parts. This creates a number of problems: (1) repeated clamping increases workload, (2) processing is carried out in multiple times, the plane processing precision is affected, the plane processing is not continuous, and the surface is not attractive.
