PROBLEM TO BE SOLVED: To provide a deformable joint assist tool which effectively shares the weight of a human body to reduce the burden on joints and is convenient for walking. A deformable joint assisting tool includes an assisting tool body, a first foot lifting mechanism, and a second foot lifting mechanism. The main body of the auxiliary tool includes an upper part, a middle part and a lower part, the middle part is connected between the upper part and the lower part, the upper end of the upper part has a support frame, and the lower end of the lower part has a supporting body. A bend is formed between the middle portion and the middle portion, and a bend is formed between the middle portion and the lower portion. The first foot lifting mechanism is connected between the upper step and the middle step of the auxiliary tool body, and the second foot lifting mechanism is connected between the middle step and the lower step of the auxiliary tool body. In order to perform the function of elastic cushioning, the upper step portion, the middle step portion, the lower step portion, the first foot raising mechanism, and the second foot raising mechanism of the auxiliary tool body all include an elastic cushioning mechanism.
