Then the motor drives the connecting shaft 203 to drive the roller 204 to move along the base 1, and the first sliding plate 202 moves to the bottom of the detection camera 4 on the second mounting frame 3 for detection. In this process, the motor on the first mounting frame 209 drives the first driving gear 210 to rotate and drive the first driven gear 208 and the rotating shaft 205 to move.
