[0030] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes:

[0031] The lamp holder 1 is a cylindrical structure, and a plurality of openings 2 are opened at equal intervals on the bottom surface of the lamp holder 1. The light source 3 is arranged in the opening 2 by means of an adjustment component 4. The light source 3 is a light source in the prior art;

[0032] The sealing ring 5 is fixedly mounted on the outer wall of the lamp holder 1, and a groove 6 is formed on the bottom surface of the sealing ring 5. A slot 7 is formed through the side wall of the groove 6. The sealing ring 5 plays a sealing role.

[0033] A sealing cover 8 is provided at the bottom end of the lamp holder 1. A connecting ring 9 is provided on the sealing cover 8. The connecting ring 9 is movably provided in the groove 6. The connecting ring 9 is provided in a manner that is in contact with the inner wall of the groove 6. The sealing cover 8 is used to protect and seal the bottom end of the lamp holder 1. A sealing gasket 19 is provided on the connecting ring 9 to improve the sealing performance of the connecting ring 9.

[0034] The limiting rod 10 is "L"-shaped and there are several of them. The limiting rods 10 are screwed into the slot 7 using a rebound shaft, and the limiting rods 10 are arranged in a conflicting manner with the connecting ring 9. The limiting rods 10 play a limiting role. The ends of the limiting rods 10 are provided with anti-wear ends 20 to prevent the ends of the limiting rods 10 from wearing;

[0035] The movable ring 11 is threadedly connected to the outer wall of the lamp holder 1 and is located above the sealing ring 5. The bottom surface of the movable ring 11 is provided with an interference groove 12. The end of the limiting rod 10 movably contacts the inner wall of the interference groove 12, making it easy to control the rotation of the limiting rod 10 through the movable ring 11;

[0036] The adjustment component 4 includes:

[0037] There are several adjusting balls 13, each of which is movably disposed in the opening 2. The light source 3 is disposed on the adjusting balls 13. The position of the light source 3 is adjusted by rotating the adjusting balls 13.
