Figure 1 and Figure 2As shown, it comprises a detection frame 1 and a lamp pole transmission mechanism, and the lamp pole transmission mechanism is provided with a lamp pole positioning member. The lamp pole transmission mechanism is used to drive the lamp pole to move, so that the lamp pole moves from the feeding position to the detection position, and after the detection is completed, the lamp pole moves from the detection position to the discharging position. The lamp pole positioning member can position the lamp pole, ensure that the position of the lamp pole remains stable during the detection process, and ensure the detection accuracy.
