Safety problems such as injuries. Therefore, it is necessary to rely on medical auxiliary equipment support, for example, using auxiliary equipment such as a wheelchair or a cane, and supporting the center of gravity of the body through the auxiliary equipment, so as to be more stable and safe when walking.

 Due to the elderly or people with inconvenient movements, due to the decline of physiological functions, their physical strength is not as good as that of ordinary people. Therefore, it is necessary to stop proper rest during the walking process and to walk again after the physical strength is restored. Therefore, relevant manufacturers have developed related devices that can be operated in a ride or auxiliary support state according to the user's needs, such as the Chinese Taiwan utility model patent "convenience cane chair" No. 85201417, mainly by the first support member and the second support member.
