When a single lens needs to be clamped, as shown in FIG. Figure 3 As shown, slide the sleeve 9 on the left L-shaped frame 7 and slide the sleeve 9 to the middle of the arc frame 4. At this time, the outer clip 11 and the inner clip 13 on the left will be in the middle of the arc frame 4, which can clamp a single lens, and a bolt is set on the rear side of the sleeve 9 for adjustment and fixation. The front sides of the two side brackets 8 are equipped with threaded rods 10, and the opposite sides of the two threaded rods 10 are equipped with outer clips 11, and are connected by bearings to ensure the normal rotation of the threaded rods 11. Limit rods are provided on the two outer clips 11, and the limit rods are slidably connected to the sliding grooves on the side brackets 8, which play a limiting role in the outer clip 11 to ensure a horizontal position.
