Such arrangement makes the optical lens 3 slide more smoothly, and improves the stability during viewing angle adjustment.

[0027] In order to facilitate the setting of the viewing angle adjustment guide rail 4 , in this embodiment, the adjustment back plate 2 and the end of the optical lens 3 close to the adjustment back plate 2 are both set to have an arc shape consistent with the curvature of the viewing angle adjustment guide rail 4 .

[0028] The locking structure in this embodiment includes an elastic buckle 5 provided on the optical lens 3 and a plurality of slots 21 provided on the adjustment back plate 2, all of which are arranged along the sliding direction of the optical lens 3, and the elastic buckle 5 cooperates with any slot 21 to achieve locking of the optical lens 3. By providing the locking structure, the locking and positioning of the optical lens 3 is achieved, the stability of the optical lens 3 after the viewing angle is adjusted is improved, and the user experience is further optimized.

[0029] The elastic buckle 5 in this embodiment includes a limiting column 51, an elastic member 52 and a limiting head 53. The limiting column 51 is a step column. A step hole is provided on the optical lens 3. One end of the limiting column 51 passes through the step hole and is connected to the limiting head 53.
