By the way, the conventional general cane has a cane body formed of wood or metal pipe material in a rod shape having a certain length, and a spherical or inverted U-shaped or L-shaped body provided at the upper end of the cane body. It is composed of a grip part. Therefore, when this type of conventional cane is used for assisting walking, the user grasps the grip portion and moves the cane body forward while moving the cane body forward on the leg side, which is inconvenient for the cane body, or It was used as an auxiliary tool during walking by repeating the motion of walking forward while putting weight on the anxious leg side and walking forward. However, in such a conventional cane, in order to move and use the cane while lifting it, it is necessary to raise and lower the cane and one's own arm. It is an absolutely necessary condition to perform weight movement while inclining the body and to walk while maintaining balance at all times, which puts a burden on the shoulder and arm muscles of the user, resulting in muscle fatigue or physical fatigue. It has the drawback of not only inducing but also mental fatigue. Therefore, in order to solve the above-mentioned conventional drawbacks, a stabilizing auxiliary leg is diverged from an appropriate position of the cane main body, and 2 is provided at one lower end of the cane main body or the stabilizing auxiliary leg.
