Embodiment 2
[0034]Embodiment 2: The difference from Embodiment 1 is that the surface of the fixed cylinder 5 is fixedly connected with the limit ring 10, the inner wall of the transmission cylinder 4 is provided with a limit groove 11, and the limit ring 10 is slidably connected in the inside of the limit groove 11. By setting The limit ring 10 and the limit groove 11 can support the fixed cylinder 5 at the same time, avoiding the left and right shaking of the fixed cylinder 5, and improving the stability of the fixed cylinder 5 when it moves.
Embodiment 3
[0035] Embodiment 3: The difference from Embodiment 1 is that both sides of the threaded sleeve 3 are fixedly connected with a backing plate 12 at the top of the fixed sleeve 7, and the top of the backing plate 12 is fixedly connected with a limit rod 13 on the side away from the threaded sleeve 3. The tops on both sides of the inner wall of the fixed cylinder 5 are fixedly connected to the limit plate 14, and the top of the limit rod 13 penetrates to the top of the limit plate 14. By setting the limit plate 14 and the limit rod 13, the fixed cylinder 5 can be limited. Position, to avoid the rotation of the fixed cylinder 5 when moving up and down, so that the oblique sealing ring 6 and the fixed sleeve 2 8 produce friction, resulting in the phenomenon that the lampshade 2 rotates and falls.
Embodiment 4
[0036] Embodiment 4: The difference from Embodiment 1 is that the side of the limiting plate 14 close to the threaded sleeve 3 is fixedly connected with a slider 15, and both sides of the threaded sleeve 3 are provided with chute 16, and the slider 15 is slidably connected to the chute 16, the top of the inner wall of the chute 16 is fixedly connected with a rubber pad 17, and the bottom of the rubber pad 17 is in contact with the top of the slider 15. By setting the slider 15 and the chute 16, the limit plate 14 can be limited. The support strength of the limit rod 13 to the limit plate 14 is improved, the phenomenon of the limit plate 14 shaking left and right is avoided, and the service life of the limit rod 13 is improved.
