Problems solved by technology
[0002] In running competitions, especially the 100-meter and 200-meter sprints, running aids are needed. Although the existing running aids meet the requirements to a certain extent, there are still some defects. The running aid has strict requirements on the spring. The spring either provides insufficient elastic force, or the elastic force is sufficient, but it is prone to heeling phenomenon, which is easy to cause athletes to sprain their feet. The patent document CN206597319U is the same, and the structure is complicated. The patent document CN103877734A discloses the use of cylinders to assist , the structure is more complicated, and the patent document CN 207119151U discloses the use of a whole elastic plate as a power-assisted device. Although its structure is simple, it cannot meet the power-assisted needs of different athletes and the elasticity is not flexible. When it is damaged, it can only be scrapped as a whole. replace
