At the same time, the convex blocking part 224 at the tail of the push rod 22 also reciprocates in the wavy blocking groove 244. Each time the convex blocking part 224 displaces through a concave-convex wavy blocking groove 244, damping and ticking sounds are generated due to space extrusion, thus forming different gear stalls. Different gear stalls can finally drive the thumb lever bracket 24 to stop at different swing angles, facilitating the user to adjust to a suitable correction angle and finally realizing the correction of the hallux valgus angle and the intermetatarsal angle to the normal state. This structure can achieve the adjustable multi-angle gear function without adding extra parts, further improving the production cost and assembly efficiency of the entire product.
