Abstract

The invention belongs to the technical field of medical equipment assistance, and particularly relates to a crutch with a variable supporting foot. The crutch includes a handle, a supporting rod, a supporting foot assembly, a supporting foot locking assembly, a supporting foot reset assembly and a fixing part; the supporting foot assembly includes a main supporting foot and an auxiliary supportingfoot; the supporting foot locking assembly is used to limit and lock the auxiliary supporting foot, so that the auxiliary supporting foot and the main supporting foot maintain a fixed opening angle;and the supporting foot reset assembly is used to reset the auxiliary supporting foot so that the auxiliary supporting foot and the main supporting foot can be combined into a supporting foot structure. The crutch can quickly and conveniently change the angle between the main supporting foot and the auxiliary supporting foot without disassembly and assembly, so that the supporting feet of the crutch can be converted into a single-foot or two-foot or three-foot state; and the supporting foot locking assembly is simple in structure and high in reliability, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of medical device auxiliary technology, and in particular relates to a crutch with variable support feet. Background technique [0002] With the intensification of the aging population in our country, the travel problem of the elderly is becoming more and more serious. For the physical condition of the elderly, walking becomes a problem due to the degeneration of leg bone function; similarly, people with disabilities or inconvenient legs and feet will also encounter similar problems.
