The width of the seat plate section frame 216 is smaller than the width between the seat slide rails 210, the armrest steel plate 208 is hinged with the lower end of the transmission section bar 211 to drive the rear end of the seat plate section frame 216 to ascend from the opening of the rear side of the rail, the flange bearing 214 on the front side of the seat plate section bar 216 slides backwards along the rail, when the flange bearing 214 slides to the tail end of the rail in the seat slide rail 210, the seat plate 215 is completely vertical, and at the moment, the posture conversion from the sitting posture to the standing posture is completed. When the posture is switched, the girdling device 4 plays a role of binding the user. When the user stands, the handrail section bar 201 rises to a proper position of the user, the user can carry out rehabilitation walking exercise by the support of the handrail section bar 201, and the waist-binding device 4 can reduce weight and help the user to prevent the user from falling. When the posture is changed from the standing posture to the sitting posture, the stepping motor 302 drives the screw rod 305 to rotate, so that the screw rod nut seat 310 descends, and simultaneously drives the LM-shaped bearing seat 207, the optical axis bearing seat, the handrail steel plate 208 and the handrail profile 201 to descend, and the handrail steel plate 208 is hinged to push the flange bearing 214 to slide forwards along the track through the lower end of the transmission profile 211 until the flange bearing 214 slides to the front end of the track.
