There are multiple first pin grooves 9 and they are evenly distributed on the inner wall of the rotating groove 5.

[0039] During operation, rotate the lighting lamp 3, the lighting lamp 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the first pin block 7 to press against the inner wall of the first pin groove 9. The spherical surface form of the first pin block 7 and the first pin groove 9 allows the first pin block 7 to slide and contract and compress the first spring 8. When the lighting lamp 3 rotates to the corresponding angular position, the first spring 8 resets and pushes the first pin block 7 to insert into the first pin groove 9 at the corresponding position, and thus the adjustment and positioning work of the first positioning mechanism can be completed.

[0040] As Figure 2 shown, a transparent protective plate 15 is provided inside the fixed groove 13 and at the outer side position of the photovoltaic panel 14. The setting of the protective plate 15 can achieve a stable protection effect.

[0041] As Figure 5 shown, the second positioning mechanism includes a second movable groove 22 provided on the inner wall of the adjustment groove 20 and a second pin groove 25 provided at the bottom of the spectacle frame 21. A second pin block 23 is nested and slidably connected in the second movable groove 22, and a second spring 24 is connected between the inner wall of the second movable groove 22 and one end of the second pin block 23.
