Abstract

The utility model provides a grounding supporting structure of a crutch. A grounding piece is connected with the bottom end of the crutch. The grounding piece comprises a base provided with a spherical guide face. The bottom end of the base is combined with a buffer block, the inner portion of the base is combined with an inner guide block, and the upper end of the base is connected with an outer sleeve, wherein the bottom end of the crutch can be sleeved with the outer sleeve. An elastic element used for supporting the bottom end of the crutch is arranged in the outer sleeve and the lower end of the outer sleeve expands outwards and is provided with an arc guide groove corresponding to the spherical guide face. A supporting rod penetrating through the bottom end of the crutch from the inner guide block and is matched with a fixing piece and fixing pivot set combination. When a user holds the crutch to walk, the bottom end of the crutch can be guided by the outer sleeve and the supporting rod so that a stable smooth rebounding buffer displacement effect can be generated, the crutch can swing universally through the spherical guide face without sliding, and therefore the purpose of comfortable, stable, safe and durable use in walking operation can be achieved.
