[0021] (5) In the present invention, the first folding plate and the second folding plate cooperate to form a clip that can be fixed on the vehicle body to achieve a fixed connection of the electronic rearview mirror.

[0022] (6) The present invention uses a fastener to firmly connect the connecting bracket to the housing, which is easy to disassemble.

[0023] (7) In the present invention, the arc-shaped block on the neutral plate can be inserted into the arc-shaped groove on the limiting plate, thereby fixing the position of the fastening member, that is, the bottom plate is fixed on the back plate.

[0024] (8) In the present invention, the second positioning column and the second positioning hole are used to cooperate with each other to achieve the initial positioning of the fixing plate and the bottom plate, and then the second hook is locked in the second slot to achieve a firm connection between the fixing plate and the bottom plate, which is convenient for disassembly.

[0025] (9) The cross section of the second positioning column in the present invention is a trapezoidal structure, so that the second positioning column can be firmly connected to the second positioning hole.

[0026] (10) In the present invention, the movable plate is fixed to the bottom plate by the bevel teeth being inserted into the bevel grooves. At the same time, the movable plate can be manually pushed upward to shrink the distance between the first folding plate and the second folding plate so that it can be clamped on the vehicle body. The cooperation of the bevel teeth and the bevel grooves can enable the movable plate to move in one direction, thereby preventing the second folding plate from loosening to ensure the firmness of the clamping. The fixed plate is firmly connected to the bottom plate to ensure that the movable plate can move in the inner cavity.

[0027] (11) The limiting ear in the present invention is installed in the card slot, so as to ensure the upward and downward movement of the movable plate to adjust the distance between the first folding plate and the second folding plate.

[0028] (12) In the present invention, the T-shaped plate is engaged with the vehicle body to achieve a firm connection. BRIEF DESCRIPTION OF THE DRAWINGS
