After the detection is completed, when the clamping force is no longer applied to the vehicle lens 3, the spring 206 applies a force to the upper clamp block 207, so that the upper clamp block 207 and the lower clamp block 210 drive the vehicle lens 3 to leave the detection position, which is convenient for the rotating disk 203 to rotate, thereby driving the vehicle lens 3 to rotate, so as to perform continuous work.

[0032] The lower surface of the upper clamping block 207 is provided with a first V-shaped groove, and the upper surface of the lower clamping block 210 is provided with a second V-shaped groove, which corresponds to the first V-shaped groove and can prevent the vehicle-mounted lens 3 from moving after clamping.
