After the tension of the leg muscles on the affected side of the patient disappears, the patient stands up with the help of family members, and the upper end of the trunk of the patient is wrapped at the armpit part of the patient through the arc frame again, so that the patient is prevented from standing unstably; the first fixing plate 27 is used for limiting the affected leg at one side of the affected leg of the patient. The patient lifts the healthy side leg, stands on the affected side leg with one leg, the gravity center of the patient moves to the affected side leg, then the driving mechanism is started, the servo motor 11 drives the gear 9 to rotate through the speed reducer 10, and the sliding block 5 is driven to move downwards through the meshing of the gear 9 and the rack 8; meanwhile, the third linear module 30 is started, the third linear module 30 drives the push rod 31 to move towards the back side of the knee of the affected leg of the patient, the back side of the knee of the leg of the patient is pushed, so that the knee of the affected leg is bent, and the baffle 29 on the first fixing plate 27 can block the knee of the affected leg, so that the affected leg is prevented from being bent excessively. Then, the servo motor 11 rotates reversely, the trunk of the patient is driven to move upwards through the arc frame, and simultaneously the third linear module 30 drives the push rod 31 to move reversely, so that the affected leg of the patient is upright. Therefore, the patient can repeatedly carry the weight to bend the knee and straighten the affected leg, the weight bearing capacity of the affected leg of the patient can be trained, and the foundation is laid for the subsequent walking training of the patient.

Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
