On one side of the outer wall, a groove 102 is opened at one end of the camera housing 1, and an isolation lens 5 is arranged inside the groove 102. A plurality of fixing holes 51 are symmetrically opened on both sides of the isolation lens 5, and the fixing rod 4 is stuck in the fixing hole 51. A screw rod 6 is rotatably connected to the upper end of one side of the camera housing 1, and a motor 61 is installed on the outer wall of one end of the camera housing 1, and the output end of the motor 61 is fixedly connected to the screw rod 6. A connecting rod 8 is threadedly connected to the screw rod 6, and a rectangular groove 80 is opened on one side of the connecting rod 8. A plurality of Velcros 81 are fixedly connected to the side wall of the rectangular groove 80, and a wiping sponge 9 is arranged on the Velcro 81. The connecting rod 8 is movably connected to a guide rod 7.

Furthermore, a lifting block 31 is fixedly connected to the side wall of the lifting rod 3 , and the lifting block 31 can be pulled to enable the lifting rod 3 to move up and down along the U-shaped bracket 2 .

Furthermore, limiting grooves 32 are provided on both sides of one end of the lifting rod 3, and the limiting blocks 41 are clamped in the limiting grooves 32. A clamping groove 401 is provided on the top of one end of the limiting block 41. The fixing rod 4 can be pulled by inserting the clamping groove 401 using professional tools.

Furthermore, a second slide groove 104 is opened on the outer side of one end of the camera housing 1, and the connecting rod 8 is stuck in the second slide groove 104, and the starting motor 61 drives the screw rod 6 to rotate, and the rotation of the screw rod 6 causes the connecting rod 8 to move along the guide rod 7.
