The positioning bead 90 and the positioning hole 20 are positioned and clamped. After the cover plate 3 is opened, the movable top shell 9 is pushed so that the position of the positioning bead 90 on the positioning hole 20 can be changed at will, and various position positioning can be performed.

[0027] Secondly, the upper end of the light board fixing tube 7 is hingedly connected to the telescopic universal head 10, the upper end of the telescopic universal head 10 is fixed to the center of the movable top shell 9, the light board 6 is fixed to the lower center of the light board fixing tube 7, the rotating light tube 5 is arranged outside the light board fixing tube 7, the lens 8 is clamped at the lower end of the rotating light tube 5 and communicates with the light board 6, and more specifically, as Figure 4 A positioning column 50 is convexly provided on the inner wall of the rotating lamp tube 5, and a positioning groove 70 is opened on the lamp board fixing tube 7. The positioning column 50 and the positioning groove 70 are slidably matched, and further preferably, the positioning groove 70 is V-shaped, so that the rotating lamp tube 5 and the lamp board fixing tube 7 can slide and rotate relative to each other along the axial direction.

[0028] In this way, after opening the cover 3, the positioning beads 90 are clamped on the positioning holes 20 at different positions, so that the movable top shell 9 can push the lamp board fixing tube 7 to the axial height position in the rotating lamp tube 5, and at the same time control the anti-glare lamp group as a whole to partially extend out of the outer tube body 1, and through the sliding cooperation of the positioning column 50 and the positioning groove 70, the position of the light board fixing tube 7 can also be adjusted by rotating the rotating lamp tube 5, and the lighting height can be adjusted by performing telescopic adjustment.

[0029] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
