The rotating first angle adjustment internal gear ring 16 can drive the second curved plate 23 fixed to it by the first connecting rod 19 to rotate together. When the second curved plate 23 rotates, the position of the cylindrical shell 7 connected to the second curved plate 23 by the transmission tube 6 will change accordingly. When the position of the cylindrical shell 7 changes, the position of the diopter 9 installed on the lower end surface of the cylindrical shell 7 will also change accordingly.

When the spherical LED lamp 4 rotates, the outer surface of the spherical LED lamp 4 will rub against the second arc-shaped cleaning sponge strip 214. Through the friction between the spherical LED lamp 4 and the second arc-shaped cleaning sponge strip 214, the outer surface of the spherical LED lamp 4 can be cleaned.

[0041] A first bevel gear 203 is fixedly sleeved on the middle position of the outer surface of the wind fan blade shaft 202, and a second bevel gear 204 is meshed on both sides of the outer surface of the first bevel gear 203, and the axis of the second bevel gear 204 is connected to a long rotating shaft 205; during the rotation of the wind fan blade shaft 202, the first bevel gear 203 fixedly sleeved on the outer surface of the wind fan blade shaft 202 and the two second bevel gears 204 meshed with the first bevel gear 203 will rotate together, and the rotating second bevel gear 204 can drive the long rotating shaft 205 connected to the axis of the second bevel gear 204 to rotate.

The rotating third bevel gear 206 can drive the fourth bevel gear 207 meshing with it and the fourth rotating shaft 208 connected to the axis of the fourth bevel gear 207 to rotate. When the fourth rotating shaft 208 rotates, the seventh gear 209 fixedly mounted on the lower side of the outer surface of the fourth rotating shaft 208 and the third inner gear ring 210 meshing with it will rotate synchronously. The rotating third inner gear ring 210 can drive the metal ring 211 fixed with it to rotate together.

[0043] An L-shaped bracket 212 is fixed to the lower end surface of the metal ring 211, and two first arc-shaped cleaning sponge strips 213 are respectively fixed to the surfaces of the two L-shaped brackets 212 facing the diffusing mirror 9; when the metal ring 211 rotates, the L-shaped bracket 212 fixed thereto will rotate therewith, and when the L-shaped bracket 212 rotates, the first arc-shaped cleaning sponge strip 213 fixed to the outer surface of the L-shaped bracket 212 will revolve around the center point of the lower end surface of the diffusing mirror 9, and the outer surface of the diffusing mirror 9 can be cleaned by the revolving first arc-shaped cleaning sponge strip 213. With the above technical solution, there is no need to install a motor or cylinder as a power source to drive the cleaning structure on the equipment, thereby further reducing the operating cost of the equipment;

[0044] When the position of the cylindrical shell 7 changes, the long rotating shaft 205 connected to it will rotate with the wind fan blade rotating shaft 202 as the center. During the rotation of the long rotating shaft 205, the second bevel gear 204 fixed on the outer surface of the long rotating shaft 205 will move and rotate along the upper end surface of the first bevel gear 203. When the second bevel gear 204 moves and rotates along the upper end surface of the first bevel gear 203, under the transmission of the gear structure, it will eventually drive the L-shaped bracket 212 to rotate. By using two bevel gears to connect the wind fan blade rotating shaft 202 and the long rotating shaft 205, it can prevent the connection between the wind fan blade rotating shaft 202 and the long rotating shaft 205 from being disconnected when the position of the cylindrical shell 7 changes.
