The lidar sensor 2 is installed on the automotive body and can detect pedestrians or obstacles when the vehicle is moving, thereby improving driving safety. During installation, the user moves the lidar sensor 2, which drives the support plate 3 to move leftward through the lidar sensor 2. The support plate 3 drives the connecting plate 4 to move leftward. The connecting plate 4 moves to squeeze the plug board 8, causing the plug board 8 to move. The plug board 8 drives the moving plate 7 to move. The moving plate 7 moves to squeeze the spring 9. The elastic potential energy of the spring 9 drives the moving plate 7 to move downward. The moving plate 7 drives the plug board 8 to insert into the slot 5.
