A movable mounting frame is connected to one end of the lead screw, and a fixed mounting frame is fixedly connected to one side of the movable mounting frame on the end face of the testing platform. The product to be tested is placed between the movable mounting frame and the fixed mounting frame.

[0005] By adopting the above technical solution, the tested product can move along the X and Y axes along the contour guide track, and it has the effects of accurate positioning, accurate counting of cycle counts, and stopping when an error occurs.

[0006] The present invention is further configured such that a control connection line for controlling the operation of the servo motor is connected between the servo motor and the servo controller.
