[0002] A projector is an optical instrument that uses optical elements to magnify the contour of a workpiece and project it onto a screen. When manufacturing projectors, multiple metal accessories are required. After these metal accessories are processed, a detection device is needed to detect the size of the accessories to determine whether their size meets the requirements. In this process, a projector metal accessory size detection device is required.

[0003] For example, a projector metal accessory size detection device with the Chinese patent application number CN202221892543.5 includes a base. One side of the top of the base is provided with a U-shaped frame, and the other side of the top of the base is provided with a mounting plate. The middle of one side of the mounting plate is provided with an electric push rod, and the output end of the electric push rod is provided with a push plate. Guide grooves are opened at both ends inside the U-shaped frame, and guide blocks are slidably connected inside the two guide grooves; through the mutual cooperation among the movable plate, the clamping plate, the electric push rod, the infrared probe, the receiving block, the U-shaped frame, spring A, chute A, the fixed block, the roller, the push plate and slider A, when the device detects the metal accessory, only by controlling the push plate to move to one side, the movable plate and the push plate can be driven to clamp on both sides of the accessory, and the two clamping plates can clamp at both ends of the accessory, quickly positioning the metal accessory and reducing the adjustment steps during the measurement of the accessory.
