[0040] Working principle: When it is necessary to flip the mirror frame 25 down, first flip the mirror frame 25 downwards. At this time, the mirror frame 25 flips downwards along the cylindrical sleeve 17. After the mirror frame 25 is completely flipped down, the stop 10 on the mirror frame 25 will push the trapezoidal block 7 upwards. At this time, the trapezoidal block 7 will compress the spring 6, and the circular hole 8 on the trapezoidal block 7 will slide upwards along the sliding rod 5. At this time, the stop 10 is locked inside the trapezoidal block 7, and then the stop 10 will be blocked between the baffle 14 and the trapezoidal block 7. When it is necessary to turn it down... When flipped up, the column head 13 is lifted upwards. At this time, the column head 13 will drive the sliding rod 9 to move upwards. The sliding rod 9 will move upwards along the elongated hole 11. The sliding rod 9 will drive the trapezoidal block 7 to move upwards. The trapezoidal block 7 will compress the spring 6. At the same time, the spring 6 will move upwards. Then, the flipping mirror frame 25 will be rotated. The flipping mirror frame 25 will then drive the stop block 10 away from the trapezoidal block 7. Then, the trapezoidal block 7 will spring back to its original position under the action of the spring 6, thus achieving the function of fixing the flipping mirror frame 25 after flipping.

[0041] When the nose bridge 16 needs to be replaced due to wear, first, the threaded sleeve 205 is unscrewed, at this time the threaded sleeve 205 is away from the threaded rod 204, then the gasket 206 is removed from the fixed rod 203, at this time the gasket 206 is away from the threaded rod 204, then the nose bridge 16 is removed from the threaded rod 204, and then a new nose bridge 16 is installed, and the gasket 206 is inserted into the fixed rod 203, and then the threaded sleeve 205 is rotated back into the threaded rod 204, so that the damaged nose bridge 16 can be replaced.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
