[0002] In machining, the workpiece is usually processed by milling, grinding and other processing by machine tools. Before the machine tool processes the workpiece, the workpiece needs to be fixed on the workbench of the machine tool. The industry usually uses vises, chucks and other fixtures to clamp the workpiece. Before clamping the workpiece, the fixture needs to be installed on the workbench of the machine tool, and then the workpiece is clamped on the fixture. Since the replacement of the workpiece needs to be carried out on the machine tool, the machine tool needs to be shut down for a long time during the replacement of the workpiece, which delays the normal operation of the machine tool and reduces the efficiency of the machine tool in processing the workpiece.

[0003] In addition, when encountering various special-shaped workpieces with a profiled surface on one side and a flat surface on the other side, it is sometimes impossible to clamp them by clamping. Even if some fixtures can solve this problem by locking or pressing plates, they cannot meet the needs of locking and fixing workpieces of different sizes and different hole spacings, and their versatility is poor.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content
