A connecting sleeve 21 is fixedly connected to one end of the mounting shell 2 facing the mounting cover 3, and the mounting cover 3 is sleeved on the connecting sleeve 21, and the mounting cover 3 and the connecting sleeve 21 are threadedly connected. An embedding groove 211 is provided on one end of the connecting sleeve 21 facing the mounting shell 2, and a gasket 22 is provided on the connecting sleeve 21, and the embedding groove 211 is for the gasket 22 to be placed. A retaining edge 31 is fixedly connected inside the mounting cover 3, and a lens is placed between the retaining edge 31 and the gasket 22. The operator can disassemble the mounting shell 2 to facilitate the replacement of lenses of different thicknesses and mounting shells 2 that match the thickness of the lenses; when the lens needs to be installed, the operator places the gasket 22 in the embedding groove 211, and then places the lens on the gasket 22, and then rotates the mounting shell 2 to thread the mounting shell 2 and the connecting sleeve 21. The mounting shell 2 can drive the movement of the retaining edge 31 to fit the retaining edge 31 with the lens, and the retaining edge 31 and the gasket 22 can limit the lens, thereby realizing the installation of the lens.

The cross section of the connecting plate 51 is L-shaped, the number of the connecting plates 51 is two and the two connecting plates 51 are arranged opposite to each other, and the connecting plate 51 is fixedly connected to the outer wall of the mounting shell 2. The first bolt 52 and the second bolt 53 are both threaded through the mounting frame 1 and the mounting shell 2, and the mounting frame 1 is provided with a second waist-shaped hole 12, and the first bolt 52 is located in the second waist-shaped hole 12 and slides. The operator can rotate the mounting shell 2 in the vertical direction, and the rotation of the mounting shell 2 can drive the rotation of the first bolt 52, so that the first bolt 52 is located in the second waist-shaped hole 12 and moves, and the second waist-shaped hole 12 can limit the movement of the first bolt 52, and the second bolt 53 can be used as the rotation axis of the mounting shell 2, so as to adjust the camera angle; when the mounting shell 2 is rotated to a suitable angle, the operator can tighten the first bolt 52 and the second bolt 53, so that the first bolt 52 is rotated to abut against the hole mouth of the second waist-shaped hole 12, and the second bolt 53 is rotated to abut against the mounting frame 1, and the first bolt 52 and the second bolt 53 can limit the mounting shell 2, so that the mounting shell 2 and the mounting frame 1 are positioned, and the mounting shell 2 is fixed after the rotation angle.
