[0029] Specifically, both ends of the rolling wheel 3 are provided with an annular limiting convex ring 32 which is connected to the rolling wheel 3 as an integral structure, and the rolling surface 31 is formed between the two annular limiting convex rings 32. The annular limiting convex ring 32 can ensure that the large track guide rib 13 and the small track guide rib 14 are always located between the two annular limiting convex rings 32, so as to prevent the rolling wheel 3 from being off the track.
