[0029] It is understandable that the staff can drive the vehicle to be tested into the light tester equipment area, pass the headlight up and down and left and right offset adjustment tool through the dimming hole of the front cabin decorative cover, completely insert the tool head 4 into the bottom of the dimming nut 3, adjust the light beam according to the display of the light tester equipment, and determine the light beam adjustment by turning the drive handle 606 counterclockwise or clockwise according to the offset displayed by the light tester.

[0030] The working principle of the above embodiment is:

[0031] (1) When testing the automobile headlights, two holes are drilled on the wall, and then one side of the support plate 503 is pressed against the wall. Then, the handle 506 is rotated. The rotation of the handle 506 drives the threaded rod 505 to rotate in the inner cavity of the threaded hole 504. The rotation of the threaded rod 505 can cause it to move to the left until the left end of the threaded rod 505 moves into the hole in the wall. The support plate 503 can be fixed. At this time, the guide cylinder 1 can be supported by the two connecting plates 502 and the two connecting rings 501, thereby reducing the labor intensity of the staff.

[0032] (2) The staff can drive the vehicle to be tested into the light tester equipment area, pass the headlight up and down and left and right offset adjustment tool through the dimming hole of the front cabin decorative cover, completely insert the tool head 4 into the bottom of the dimming nut 3, and adjust the light beam according to the display of the light tester equipment. According to the offset displayed by the light tester, the light beam adjustment is determined by turning the driving handle 606 counterclockwise or clockwise. The staff can manually turn the driving handle 606. The rotation of the driving handle 606 drives the driving plate 605. The rotation of the driving plate 605 rotates the rotating sleeve 602. The rotation of the rotating sleeve 602 rotates the shaft 601. The rotation of the shaft 601 can drive the connecting rod 2 in the inner cavity of the guide cylinder 1. The rotation of the connecting rod 2 can drive the dimming nut 3 and the cutter head 4 to rotate, thereby adjusting the light beam. The staff can also drive the rotating sleeve 602 to rotate through the driving motor 603, so that the shaft 601 rotates, and the dimming nut 3 and the cutter head 4 can also be driven to rotate.
