By arranging the protective plates 302 at the front and rear ends of the support plate 2, the self-moving tail body 1 can be protected. In addition, when the movable block 301 is rotated on the support plate 2, the protective plate 302 can be driven to rotate as well, thereby controlling the outward opening angle of the protective plate 302 and adjusting the protection range. The operation is simple and convenient, and the applicability is improved.

[0024] In one embodiment of the utility model, two groups of movable blocks 301 are provided, and the specifications and sizes of the two groups of movable blocks 301 are different. When the two groups of movable blocks 301 are rotated inward, the protective plate 302 can be driven to rotate toward the direction of the support plate 2, and the protective plate 302 can be stored. When not in use, the storage area of ​​the space is reduced.

[0025] Please continue reading Figure 1-Figure 3A slot 3011 is provided at the upper end of the movable block 301. The slot 3011 has multiple groups and is arranged in a circular array. A limit rod 304 is inserted into the slot 3011. A slide groove is provided inside the protective plate 302. A sliding plate 4 is slidably connected in the slide groove.
