The vertical line I of the reflective surface and the reflective surface 24 are perpendicular to each other, and the angle H between the vertical line I of the reflective surface and the rotation axis G is between 20° and 70°. Through the design of the angle H between the vertical line I of the reflective surface and the rotation axis G, the mirror 20 is obliquely connected to the rotation axis 10 . When the rotating shaft 10 rotates, it will drive the mirror 20 to rotate together. At this time, since there is an angle H between the vertical line I of the reflection surface and the rotation axis G, it can make the mirror 20 reflect the received light rays L, L1, L2 to a specific direction; therefore, the reflective surface 24 of the mirror 20 can reflect the light rays L, L1, and L2 corresponding to the rotation angles A, A1, and A2 of the rotating shaft 10 to a specific direction; in this embodiment, the reflective surface 24 of the mirror 20 will Reflect the light rays L, L1, L2 to the direction corresponding to the rotation axis G.
