The buffer spring 4 can play a buffering role when the guard plate touches the ground, reducing the deformation of the guard plate and extending its service life. In this embodiment, the buffer spring 4 is arranged on the cross beam 101 through the positioning mechanism. The clamping mechanism fixes the guard plate body 2. After the guard plate body 2 is damaged, the damaged guard plate body 2 can be replaced, reducing the replacement cost compared with replacing the whole. In other embodiments of the present utility model not shown in the figure, a plurality of connecting beams are arranged inside the frame 1 to improve the strength of the frame 1. For example, vertical connecting beams are arranged between the cross beam 101 and the frame bracket.

[0024] See Figure 2 , the structure of the positioning mechanism in this embodiment is as follows: The positioning mechanism includes a positioning groove 5, a positioning block 6, and a connecting plate 7. The positioning groove 5 is opened on the surface of the frame 1. In this embodiment, the positioning groove 5 is arranged on both sides of the cross beam 101.
