At this time, the two limit plates 56 no longer limit the movement of the device, and the patient can push the device to perform assisted walking training by holding the two handles 13.

[0055] In the process of the movable L-shaped bracket 19 moving upward, the cooperation of the L-shaped toothed plate 20, the gear 2 91, the worm 2 92 and the worm wheel 2 912 can drive the rotating rod 3 913 to rotate, and the rotation of the rotating rod 3 913 can drive the two rotating sleeves 1 97 to rotate under the action of the four guide blocks 1 arranged thereon, and the rotation of the two rotating sleeves 1 97 can drive the two bevel gears 3 98 to rotate accordingly, and then the two rotating rods 4 72 can be driven to rotate under the action of the two bevel gears 4 74, and the rotation of the two rotating rods 4 72 can drive the two mounting frames 711 to rotate upward by ninety degrees relative to each other under the action of the two rotating sleeves 2 710, until the two mounting frames 711 rotate to a horizontal state, at which time the protective rollers 1 712 arranged on the two mounting frames 711 can protect the patient's back;

[0056] During the patient's walking training, the four protective rollers 73 can protect both sides of the patient, and the patient can also overlap his arms on the two overlapping rollers 79 according to his own situation during the walking training, and then push the device to perform walking training by holding the two handles 13 with both hands. In this process, the two overlapping rollers 79 can support the patient and increase the patient's stability during the walking training. The patient can also adjust the position height of the two overlapping rollers 79 according to his own situation through the cooperation of the adjustment vertical plate 75, the latch 76, the spring 77 and the square frame 78.

It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
