Optionally, the second locking member 11 is screwed into the second locking hole 10, and the second locking member 11 can be an M2.5 screw.

[0028] Furthermore, a spring 12 is sleeved on the second locking member 11, and the spring 12 is located at the portion of the second locking member 11 outside the through hole 8, and both ends of the spring 12 are respectively in contact with one end of the second locking member 11 away from the first mounting plate 2 and the side wall of the first mounting plate 2 away from the adjustment mirror seat 4; the spring 12 can be a compression spring;

[0029] Thus, the second locking member 11 is screwed into the rotating shaft 9, and the elastic force of the spring 12 can provide a pre-tightening force to the adjustment mirror base 4, so as to prevent the adjustment mirror base 4 from falling or twisting due to gravity;

[0030] It should be noted that the through hole 8 and the rotating shaft 9 need to be properly matched. If the gap between the through hole 8 and the rotating shaft 9 is small, it will lead to difficulties in installation and adjustment; if the gap between the through hole 8 and the rotating shaft 9 is large, it will lead to insufficient adjustment accuracy.

[0031] Two first locking holes 6 are further provided on the first side wall, and the two first locking holes 6 are respectively located on both sides of the through hole 8 and are respectively arranged corresponding to the two arc-shaped strip holes 3.
