The measuring plate and the spring are set to three groups to achieve the effect of multiple measurements on special workpieces.

[0016] 2. Through the mutual cooperation among the rack, gear and driving shaft of the moving device of the utility model, the belt is driven to rotate. The belt rotation drives the driven shaft. The driven shaft rotation drives the driving gear to rotate. The driving gear rotation drives the driven gear to rotate through the gear belt. All components move simultaneously through the meshing relationship, realizing the transportation of workpieces. When the workpiece moves to the end of the gear belt through the gear belt, the workpiece will squeeze the air pressure stress rod to move into the L-shaped air cylinder, thus saving labor. When the workpiece is being pushed by the push plate, to prevent the workpiece from falling off the workbench, the limiting plate realizes this function. Such a design not only reduces the labor force but also plays a role in safety protection.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings
