[0023] The reflector body 1 can be a flat surface or a curved surface for reflecting and changing the light path. A rotating shaft 11 is fixedly arranged on the back of the reflector body 1. In this embodiment, the rotating shaft 11 is kept in a horizontal state so that the reflector body 1 can be pitched up and down. An ear plate for mounting the rotating shaft 11 is arranged on the back of the reflector body 1.

[0024] The mounting seat 2 is used to mount the reflector body 1 and serves as a rotating carrier of the reflector body 1 .

The connecting part 21 is configured as a rectangular block structure; the connecting plates 22 are configured as long strips, and there are two of them. The two connecting plates 22 have vertical plate surfaces and are relatively fixed at the front end of the connecting part 21. An installation cavity in the vertical direction is formed between the two connecting plates 22, and the upper and lower directions and the front end of the installation cavity are both connected to the outside; the translational sliding rod 23 is configured as a square rod with a cross-sectional size smaller than the cross-sectional size of the connecting part 21. The translational sliding rod 23 can be connected to any of the five side surfaces of the connecting part 21 except the side surface on which the connecting plate 22 is provided. In this embodiment, it is configured on the side surface opposite to the side surface on which the connecting plate 22 is located, and the translational sliding rod 23 is fixed to the connecting part 21 through the front end surface; the fixing sleeve 24 is configured as a square sleeve, and the shape of the inner hole is the same as the cross-sectional shape of the translational sliding rod 23. In this embodiment, the fixing sleeve 24 is fixedly connected to the carrier carrying the reflector system, that is, the equipment rack or shell of the reflector system, and the fixing sleeve 24 can maintain a relatively fixed state with the equipment.

[0025] The reflector body 1 is rotatably connected to the mounting base 2 via a rotating shaft 11, and the rotating shaft 11 is rotatably connected to the front ends of the two connecting plates 22, that is, one end away from the connecting portion 21.

The number of circles of the driving gear 43 is used to control the deflection angle of the driven gear 41 and even the reflector body 1. The larger the transmission ratio is set, the higher the rotation accuracy of the reflector body 1 will be and the more convenient the control will be.
