[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. According to the difference in processing methods, machining can be divided into cutting and pressure processing. When machining a workpiece, a fixing mechanism is required to fix it.

[0003] Through searching, a machining clamping fixture with publication number CN210967956U was found. The handle can be used to move the limiting plate, thereby increasing the distance between the limiting plate and the fixed plate. The limiting plate and the buffer plate can then be moved downward, making it easier to place the material on the platform and saving manpower. The buffer plate can then be brought into contact with the material through the stretching spring and the connecting spring, allowing the limiting plate to automatically move upward, reducing manual operation and making it easier to clamp the material.
