The structure according to claim 8, characterized in that a spherical washer (9) is arranged between the fine-tooth adjusting screw (10) and the adjusting disk (7), the spherical washer (9) comprises a concave washer (21) and a convex washer (22), one end of the concave washer (21) is a plane and is in contact with a countersunk flat surface of the adjusting screw through hole (18); the other end of the concave surface gasket (21) is an inward concave spherical surface and is matched with the outward convex spherical surface of the convex surface gasket (22), and the other end of the convex surface gasket (22) is a plane and is contacted with the front end face of the screw head of the fine tooth adjusting screw (10).
10. An adjusting method is characterized by comprising the axial position adjustment of a reflector in an optical path and the angle adjustment of the reflector in two directions of pitching and deflecting;
the axial position of the reflector in the light path can be adjusted by changing the matching position of a threaded rod of the adjusting rod (4) and an adjusting rod connecting threaded hole (16) on the adjusting disc (7); firstly, properly loosening or taking down the fine-tooth adjusting screw (10), rotating the locking nut (8) to enable the locking nut to be away from the adjusting disc (7) for a distance, then rotating the adjusting rod (4), changing the relative position of the adjusting plate (3) and the adjusting disc (7) until the reflector (1) is in a proper axial position in the light path, and after the position is adjusted, re-installing the fine-tooth adjusting screw (10) and locking the locking nut (8);
the angle adjustment of the reflector in two directions of pitching and deflecting can be realized by changing the matching length of a threaded rod of a fine-tooth adjusting screw (10) and a fine-tooth threaded hole (15) on the adjusting plate (3); according to the direction to be adjusted, one of the fine-tooth adjusting screws (10) is screwed down, the other screws are loosened, or two of the fine-tooth adjusting screws (10) are screwed down, the other screw is loosened, so that the adjusting plate (3) rotates angularly by taking the spherical center of the ball socket (12) as a rotating center, and the angle of the reflector is changed.
