Abstract: An auxiliary handle for a walking assistance device has a tube seat and a handgrip tube. The tube seat utilizes the positioning space for accepting a crutch tube. When a user holds the handle portion of the handgrip tube and turns it downward; when the handgrip tube is turned, the positioning protrusion of the connecting portion moves from the stopping portion to the positioning portion and compresses the elastic member. When the handgrip tube is horizontal, the positioning protrusion passes over the stopping edge and inserts into the positioning portion for positioning to lock the handgrip tube and prevent the elastic member from rebounding. Meanwhile, the user holds a top grip on the top of the walking assistance device with one hand, and holds the handgrip tube with the other hand, and then applies force to support the body to get up and stand.

Abstract: A walking stick may include a tube body, a first telescopic tube, a second telescopic tube, and a third telescopic tube. The tube body is a hollow tube, and at least a positioning hole is formed thereon, and a top end and a bottom end of the tube body respectively connect to a handle and a locating sleeve. The first telescopic tube upwardly inserted into the tube body comprises a first locating piece. Also, the second telescopic tube upwardly inserted into the first telescopic tube has a second locating piece while the third telescopic tube upwardly inserted into the second telescopic tube comprises a third locating piece. A user only needs to press the first locating piece when the walking stick needs to be retracted, and the second telescopic tube and the third telescopic tube are sequentially retracted, which is convenient for operation.
