Detailed Description

For better understanding of the objects, structure and functions of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the present invention includes: a mounting arm 1, a mounting base 2 sleeved outside the mounting arm 1, and a limit bolt 3 arranged on the mounting base 2, wherein,

the mounting arm 1 is of a rectangular block structure, the two sides of the mounting arm are smooth surfaces, and the two sides of the middle part of the mounting arm are provided with a plurality of tooth shapes for meshing a plurality of gears 4, so that the mounting arm 1 forms a rack type mounting arm which is used for being inserted into the mounting base 2 and fixing the rearview mirror;

the mounting base 2 is a n-shaped shell with a closed outer surface and an open front surface, the front part of the shell is exposed and can be movably sleeved outside the mounting arm 1, the shell can move up and down, and the shell is used for mounting a rack and building an internal structure of the mounting base 2.

The upper smooth surface of the mounting arm 1 protrudes out of the upper part of the mounting base 2, and the lower smooth surface is arranged in the mounting base 2 and is flush with the bottom of the mounting base 2.

The limiting bolt 3 is arranged in a bolt hole 6 formed in the middle of the mounting base 2 and used for locking the gear 4 and further fixedly mounting the rack on the arm 1.

The gear 4 is a gear of the mirror, and is used for guiding the rack and limiting after the limiting bolt 3 is tightened.
