[0002] A fixture is a device used to fix a workpiece in place for machining, measurement, or inspection. Fixtures have a wide range of applications. They help ensure that the workpiece remains correctly positioned during machining and can withstand the forces generated during machining without moving, thus guaranteeing machining accuracy and quality. Simple fixtures are those with a simple structure that are easy to manufacture and use. These fixtures are typically suitable for applications that do not require high-precision positioning or mass production; they can be quickly installed and adjusted, and are relatively inexpensive. The main purpose of simple fixtures is to conveniently fix workpieces, keeping them stable during machining, measurement, or assembly.

[0003] Existing fixtures are not convenient for quick installation and adjustment during use, and their operating costs are high. The excessive time required for fixture installation and adjustment directly affects the speed of the entire production process. Each time a workpiece is changed, a significant amount of time is needed to reset the fixture, which significantly increases non-productive time and thus reduces overall production efficiency.
