[0002] Metal castings are metal shaped objects obtained by various casting methods. They are obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, waiting for it to cool, and then polishing and other subsequent processing methods to obtain objects with certain shapes, sizes and properties. In the process of processing metal castings, a fixing device is needed to fix the metal castings to avoid the position displacement of the metal castings during the processing.

[0003] A patent document with publication number CN218984548U discloses a fixing fixture for processing metal castings. The fixing fixture for processing metal castings uses a telescopic rod and a limit rod to enable a slider to achieve an automatic movement and limit effect, thereby facilitating automatic limit and fixation of the casting.
