[0002] A fixture is used to quickly fasten the workpiece during processing. It is also called a clamp. It is a process device that keeps the machine tool, tool and workpiece in the correct relative position. Tooling fixtures are indispensable components in mechanical processing. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent and environmentally friendly directions, fixture technology is developing towards high precision, high efficiency, modularity, combination, universality and economy.

[0003] When the fixture is processing the workpiece, it often relies on the operator to use a separate ruler for comparison and observation.
