The lamp 25 is movably connected through the upper cover 2, and the external wire 5 is movably connected to the lamp 25, ensuring stable electrical connection and good waterproof performance.

[0030] Specifically, gear grooves 24 are provided on the sides of the first moving block 21, the second moving block 22, and the third moving block 23, and slots 19 are provided on the sides of the semicircular guide rail 12. The slots 19 are movably connected to the gear grooves 24. A drive gear 15 is movably connected inside the outer casing 1.

[0031] Specifically, a symmetrical positioning shaft 13 is fixedly connected inside the outer casing 1. A driven gear 14 is correspondingly sleeved on the positioning shaft 13.

[0033] Working principle:

[0034] The upper cover 2 is fixed to the outer casing 1 by passing the fixing button 6 through the connecting hole 8 of the upper cover 2 and the support block 7, thus completing the installation and fixing of the lamp 25. The external power cord 5 is connected to the lamp 25 through the external pipe 4 to ensure stable power supply and waterproof performance. When it is necessary to adjust the direction and range of light projection, the rotary motor 20 at the lower end of the outer casing 1 is started. The rotary motor 20 drives the drive gear 15 to rotate. The drive gear 15 meshes with the driven gear 14 on the positioning shaft 13, transmitting power to the driven gear 14. The drive gear 15 and the driven gear 14 mesh with the gear grooves 24 on the sides of the first moving block 21, the second moving block 22, and the third moving block 23. Guided by the slot 19 on the side of the semicircular guide rail 12, the three moving blocks are driven to move along the semicircular guide rail 12. The first moving block 21, the second moving block 22, and the third moving block 23 respectively drive the first transparent plate 9, the second transparent plate 10, and the third transparent plate 11 to move within the transparent plate 3. By adjusting the position of the three transparent plates, the light refraction path is changed, allowing for flexible adjustment of the light projection angle and coverage. Simultaneously, the heat dissipation hole 16 on the other side of the housing 1, in conjunction with the rubber ring 18 and the filter 17, ensures that the heat generated by the lamp 25 is dissipated in a timely manner while blocking dust, maintaining a good working environment.
