[0024] When it is necessary to adjust the height of the detector 5 or replace the detector 5, the servo motor drives the screw 8 to rotate, and the screw 8 drives the vertical plate 3 to slide on the fixed frame 1. At the same time, the vertical plate 3 drives the support plate 4 and the detector 5 to move and descend. When it is in a higher position, it is convenient for the staff to replace the detector 5, and the height of the detector 5 can also be adjusted. By setting the fixed frame 1 in reverse, the detector 5 can be raised.
