[0027] During operation, the pitch angle of the lidar body 20 is detected and calculated by using the electrical connection method between the camera 130 and the calculation module in the comparative document; when installing the lidar body 20, first use the electric push rod 157 to drive the lower pressing seat 156 to move upward in the vertical direction, so that the distance between the lower pressing seat 156 and the mounting seat 141 is increased, thereby facilitating the placement of the lidar body 20 on the mounting seat 141. After the placement is completed, the adjustment plates 144 on the four sides are driven to move by screwing the four-side threaded rods 143 to clamp the lidar body 20. After the clamping is stable, use the electric push rod 157 to drive the lower pressing seat 156 to move vertically downward, so that the rubber pad fixedly connected to the end of the buffer rod 158 contacts the top of the lidar body 20. Then start the motor 154 and use the motor 154 to drive the lower pressing seat 156 to rotate, so that the microfiber cloth 159 fixedly connected to the inner wall of the lower pressing seat 156 can be used to clean the lens of the lidar body 20.
