[0005] As an improvement, the side of the installation groove may preferably be provided with a side wall opening for inserting the lens, and a limiting block capable of contacting the lens is provided at the opening of the side wall opening.

[0006] As a further improvement, a convex edge which can fit on the opening of the sun visor groove can be preferably provided on the outer ring of the lens frame.

[0007] As a further improvement, an extension rod may be preferably provided on the side wall opening of the installation groove, the limit block is provided on the extension rod, and the extension rod extends out of the convex edge.

[0008] As a further improvement, the width between the two extension rods may preferably be greater than the width of the mirror cover, so that when the mirror cover slides back and forth along the mirror frame, a gap is left between the side wall of the mirror cover and the extension rods.

[0009] As an improvement, a plug-in protrusion which can be plugged into a sun visor groove may preferably be provided at the bottom of the lens frame.

[0010] As a further improvement, the plug-in protrusion may preferably be made integrally with the frame.

[0011] As an improvement, a handle protrusion may preferably be provided on the top surface of the mirror cover.

[0012] As an improvement, a mirror cover limiting groove capable of accommodating the mirror cover may preferably be provided at the bottom of the mounting groove, and a sliding groove capable of plugging into the corresponding side of the mirror cover may be provided on the side wall of the mirror cover limiting groove, and when the mirror cover slides back and forth along the sliding groove, a gap is left between the bottom surface of the mirror cover and the lens.

[0013] As a further improvement, the area of ​​the central opening of the lens frame may preferably be smaller than the area of ​​the lens and the lens cover.

[0014] Compared with the prior art, the advantages of the utility model are: the lens is positioned by the bent limit plates distributed at intervals at the top opening of the installation groove, no glue is needed, the lens is fixed by a purely mechanical structure, and it is very environmentally friendly. The limit plate is an integral structure formed by injection molding with the frame, the structure is simple and compact, and the lens installation efficiency is also improved.
