[0014] In the present invention, by providing a fixing mechanism, when the driven frame moves upward, it drives the extension rod to move upward. When the extension rod moves, it drives the fixing ring to move upward. When the fixing ring moves, it pulls the telescopic driven frame to extend upward. When the driven frame moves upward, it also pulls the pull rod to move upward. When the pull rod moves, it pulls the moving box to slide on the inner wall of the groove in the direction of approaching each other. When the moving frame slides, it pushes the limiting elastic rod to contract in the direction of approaching each other. When the moving frame slides to a certain position, the two moving frames are limited by the limiting elastic rod to prevent the two moving frames from coming into contact. When the moving frame slides, it drives the telescopic driven frame to move in the direction of approaching each other. When the telescopic driven frame moves, it pushes the fixing ring to move in the direction of approaching each other to fit the waist of the athlete. When the fixing ring moves, it pulls the extension rod to extend in the direction of approaching each other, effectively fixing the athlete and supporting the waist of the athlete so that the athlete can walk slowly alone, achieving the effect of being able to train and rehabilitate alone and saving the need for others to support.

[0015] In the present invention, by providing a support mechanism, when the driven frame moves upward, it drives the support telescopic frame to move upward. When the support telescopic frame moves, it drives the rubber soft pad to move upward. When the support telescopic frame moves, it drives the fixing frame to move upward. When the driven frame moves upward, it also drives the limiting telescopic rod to move upward. When the limiting telescopic rod moves, it drives the passive frame to extend upward. When the telescopic driven frame moves, it drives the passive frame to move in the direction of approaching each other. When the passive frame moves, it pushes the limiting telescopic rod to contract in the direction of approaching each other. When the limiting telescopic rod contracts to a certain position, it limits the passive frame. By using the limiting telescopic rod to limit the passive frame, it prevents the passive frame from coming into contact with the surface of the driven frame. When the passive frame moves, it pushes the telescopic push rod to move in the direction of approaching each other. When the telescopic push rod moves, it drives the support telescopic frame to extend upward. The height of the support telescopic frame can be adjusted according to the height of the upper body of the athlete. When the support telescopic frame moves, it drives the rubber soft pad to move upward. The athlete can place the armpit on the surface of the rubber soft pad. Since the rubber soft pad is relatively soft, it can increase the comfort of the athlete. When the support telescopic frame moves, it also drives the fixing frame to move upward. When the fixing frame moves, it drives the grip to move upward. When the athlete places the armpit on the surface of the rubber soft pad, the palm can hold the surface of the grip, making it more convenient for the athlete to turn.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
