By setting the arc hole 619, the latch pin 614 is given space to avoid the space. By setting the latch pin 614, the position of the limiting ring 617 is driven to change.

[0039] In this embodiment, the surface of the latch pin 614 is fixedly connected to a limiting ring 617, the limiting ring 617 is adapted to the circular hole 632, the surface of the latch pin 614 is sleeved with a second return spring 613, the top end of the second return spring 613 is fixedly connected to the surface of the latch pin 614, and the bottom end of the second return spring 613 is fixedly connected to the surface of the rear wheel bracket 1.

[0040] By providing the second reset spring 613, the latch 614 is driven to move and reset to maintain stability.

[0041] As a preferred implementation scheme in this embodiment, the surface of the front wheel bracket 2 is fixedly connected to a vertical plate 611, one side of the vertical plate 611 is fixedly connected to a small motor 618, the output end of the small motor 618 passes through the surface of the vertical plate 611 and is fixedly connected to a rotating plate 621, and the inner wall of the rotating plate 621 is fixedly connected to a second L-shaped plate 627.

[0042] By setting up the vertical plate 611, the small motor 618 is supported and the movement of the support plate 620 is guided. By setting up the small motor 618 and starting the small motor 618, the output end of the small motor 618 drives the rotating plate 621 to rotate, the rotating plate 621 drives the second L-shaped plate 627 to rotate, and the second L-shaped plate 627 drives the position of the convex shaft 628 to change.

[0043] In this embodiment, the inner wall of the vertical plate 611 is slidably connected to a support plate 620 , the top of the support plate 620 is fixedly connected to a moving plate 622 , a guide hole 625 is opened on one side of the moving plate 622 , and a second L-shaped plate 627 is installed in the guide hole 625 .

[0044] By providing the moving plate 622 , the movement of the support plate 620 is guided and supported, and by providing the guide hole 625 , space is avoided for the movement of the second L-shaped plate 627 .

[0045] In this embodiment, the inner wall of the moving plate 622 is slidably connected to a slider 626, a surface of the slider 626 is provided with a straight hole 629, the surface of the second L-shaped plate 627 is fixedly connected to a convex shaft 628, the convex shaft 628 is installed inside the straight hole 629, the surface of the slider 626 is fixedly connected to a C-shaped clip 623, and the surface of the C-shaped clip 623 is fixedly connected to a Velcro 624.

[0046] By setting a slider 626, the C-shaped clamp 623 is driven to make an elliptical motion. By setting a slotted hole 629, space is avoided for the movement of the convex shaft 628. By setting a Velcro 624, in cooperation with the C-shaped clamp 623, the patient's legs are fixed, and the patient's legs are driven to make an elliptical motion, so that the soles of the feet are in contact and friction with the ground, thereby driving the rear wheel bracket 1 and the front wheel bracket 2 to move as a whole.

[0047] The working principle of the present invention is as follows: a foldable portable walker, when used by a user, the patient sits on the support cloth 604, holds the hand grip 4 to keep stable, and controls the braking movement of the wheel on the rear wheel bracket 1 by setting a brake pressing ring 5 to ensure safe use, and after the patient's legs are fixed between the Velcro 624 and the C-shaped clip 623, the small motor 618 is started, and the output end of the small motor 618 drives the rotating plate 621 to rotate, and the rotating plate 621 drives the second L-shaped plate 627 to rotate, and the second L-shaped plate 627 is rotated. The plate 627 drives the position of the convex shaft 628 to change, and the convex shaft 628 rotates in the slotted hole 629, driving the slider 626 to slide in the moving plate 622. At the same time, the moving plate 622 drives the support plate 620 to move up and down, thereby causing the slider 626 to drive the C-shaped clip 623 to make an elliptical motion. The Velcro 624 cooperates with the C-shaped clip 623 to fix the patient's legs, driving the patient's legs to make an elliptical motion, so that the soles of the feet contact and rub against the ground, driving the rear wheel bracket 1 and the front wheel bracket 2 to move as a whole, and performing rehabilitation exercise. When the device is not in use and needs to be stored as a whole, the positioning pin rod 605 is pulled outward to release the plug-in state of the positioning pin rod 605 and the positioning hole 606. At this time, the pair of height adjustment frames 3 are moved closer to each other, so that the first rotating rod 602 and the second rotating rod 603 rotate and adjust adaptively. At this time, the ring 608 is driven by the supporting column 609 to receive force, so that the sliding sleeve 631 slides upward along the surface of the height adjustment frame 3. The supporting cloth 604 is made of cloth and will not affect the storage. Then the operator can pull out the pin rod 605 upward to remove the positioning pin rod 605 and the positioning hole 606. 14. The movement of the latch 614 drives the limiting ring 617 originally in the circular hole 632 to move into the avoidance hole 612. At this time, the operator can rotate the front wheel bracket 2 as a whole, so that the front wheel bracket 2 and the rotating plate 610 are rotated and adjusted with the fixed plate 615 as the axis, and the plug plate 616 is rotated out of the slot 630. At this time, the arc hole 619 avoids the latch 614 and will not block the plug plate 616 as a whole. With the above structure, it has high stability and is easy to fold and carry. When in use, it assists patients in leg walking rehabilitation training.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
