Each spring damper 15 passes through the surface of the side frame 2 and is fixedly connected to the anti-collision plate 6. When the frame tilts to both sides, the anti-collision plate 6 first contacts the ground. The arc at the bottom of the anti-collision plate 6 can avoid direct collision with other hard objects to cause more serious damage. When the anti-collision plate 6 is subjected to impact force, the spring damper 15 will be compressed.
