[0002] Coordinate measuring machines are widely used in industries such as machinery, electronics, instrumentation, and plastics. They are one of the most effective methods for measuring and obtaining dimensional data because they can replace multiple surface measurement tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, a result that other instruments cannot achieve.

However, when using the existing three-dimensional coordinate measuring machine, the workpiece to be measured is mostly fixed on the measuring workbench. When different surfaces of the workpiece to be measured need to be inspected, the bottom position of the workpiece to be measured and some positions located in the blind spot of the inspection usually require the staff to disassemble and adjust the position of the workpiece to be measured. The repeated disassembly and adjustment and then fixing it again are troublesome operations and reduce efficiency. Summary of the Invention
