Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the first embodiment, as shown in fig. 1 to 4, the lower limb exercise assisting chair for cerebrovascular disease rehabilitation comprises a balancing rod 3, wherein two ends of the balancing rod 3 are sleeved with positioning sleeves 4, an anti-slip plate 5 is fixed in the middle of each positioning sleeve 4, the upper end of the balancing rod 3 is connected with a supporting rod 6, the upper end of the supporting rod 6 is fixed with a rotating tube 7, the upper end of the rotating tube 7 is rotatably connected with an adjusting knob 1 through threads, the inside of the rotating tube 7 is rotatably connected with a connecting column 8, and two ends of the connecting column 8 are connected with pedals 2;

the connecting column 8 comprises an upper column body 81, the lower end of the upper column body 81 is connected with a limiting pipe 85 in a sliding mode, a spring 82 is arranged inside the limiting pipe 85, a middle column body 83 is fixed at the lower end of the spring 82, and the lower end of the middle column body 83 is connected with a lower column body 84 through the spring 82 and the limiting pipe 85.
