After determining the position, the plug 4 can be pulled out, and the crossbeam 5 and the infrared transmitter 6 can be rotated toward the direction of the electric cylinder 10. After determining the position, loosen the first fastening screw 9, and the adjustment groove can be used to slide the abutment plate 7 so that multiple abutment plates 7 are against the outer wall of the lens toward one end of the lens, and then tighten the first fastening screw 9 to fix the abutment plate 7, and then a weight 19 of the required weight is set on the outer wall of the weight rod 17 of the connecting head 14, so that the grinding head 16 is pressed and moves downward to contact the outer wall of the lens, and then the electric cylinder 10 controls the skateboard 3 to translate back and forth, so that friction occurs between the lens and the grinding head 16, and the degree of lens wear under a certain period of time is tested.
