The armrest board 11 can also be in other configurations, such as circular, V-shaped. The at least one armrest panel 11 may also include other numbers of armrest panels. The lower support assembly 20 includes movement means 50 for moving the walker 1 and defines a standing space for the patient. The walker 1 further includes an intermediate support rod 30 , the upper part of which is fixedly connected with the upper support assembly 10 , and the lower part of the intermediate support rod 30 is rotatably connected with the lower support assembly 20 . It should be noted that the "fixed connection" mentioned herein means that the two are fixed relative to each other in the connected state. It is understood that the upper portion of the intermediate support rod 30 and the upper support assembly 10 may be permanently connected (eg, welded or integrated), or may be detachably connected (eg, connected by threaded fasteners). Preferably, the moving device 50 includes a driving wheel 51 and a driven wheel 52 . More preferably, the driving pulley 51 is disposed below the end of the lower support assembly 20 away from the intermediate support rod 30 , and the driven pulley 52 is disposed under the end of the lower support assembly 20 close to the intermediate support rod 30 . The intermediate support bar 30 is provided with a seat 40 for the patient to sit on. The upper support assembly 10 and the intermediate support rod 30 can be rotated together relative to the lower support assembly 20, for example by 180°, thereby enabling the walker 1 to operate in the autonomous walk mode shown in FIGS. 1 to 4 and FIGS. 5 to 8 . Toggles between the other push modes shown.
