[0026] The lateral distance adjustment mechanism includes two side slide plates 7 and a slide groove 13. The slide groove 13 is formed on the side wall of the annular plate 5. The two side slide plates 7 are respectively fixed above the two spotlights 6, and the two side slide plates 7 are slidably arranged on both sides of the slide groove 13. Side bearings 15 are fixed on both sides of the slide groove 13. A bidirectional threaded rod 14 is connected in one of the side bearings 15. One end of the bidirectional threaded rod 14 passes through the two side slide plates 7 and the other side bearing 15 and is fixed with a side rotation handle 16. The bidirectional threaded rod 14 is threadedly connected to the two side slide plates 7. Rotating the side rotation handle 16 can drive the bidirectional threaded rod 14 to rotate. The rotation of the bidirectional threaded rod 14 can drive the two side slide plates 7 to move towards each other in the slide groove 13.

[0028] The working principle and usage of this utility model are as follows: The spotlights 6 on both sides of the annular plate 5 illuminate the patient's eyes. Rotating the side handle 16 rotates the bidirectional threaded rod 14, which in turn moves the two side slides 7 towards each other within the slide groove 13. This movement of the side slides 7 adjusts the distance between the two spotlights 6, thus better illuminating people with different eye distances. The angle adjustment mechanism rotates the rotating plate 17 on one side above the upper plate 4, which in turn rotates the two spotlights 6, allowing adjustment of their illumination angles.
