In the rotation, the cylinder clamping jaw 1221 or the clamping jaw of the symmetrical clamping moving mechanism 1224 is required to clamp the mirror body, so that the mirror body is driven to rotate around the axis of the mirror body. In the clockwise rotation process, when the rotation angle exceeds 90 degrees, the photoelectric trigger arc 1225 triggers the left switch of the rotary photoelectric switch 1005, and the controller sends a signal to reverse the rotary motor 1101.
