[0023] Further improvement, such as Figure 2 As shown, the outer end width of the leg sleeve 1 6 is greater than the inner end width, a placement groove 15 is formed inside the leg sleeve 1 6 , and the leg sleeve 2 7 has the same structure as the leg sleeve 1 6 .

[0024] Further improvement, such as Figure 2 As shown, the support rod 9 is a two-section structure and comprises a main tube 16 and an insertion rod 17 longitudinally inserted into the main tube 16. The main tube 16 and the insertion rod 17 are respectively mounted on the leg sleeve 2 7 and the leg sleeve 1 6. In the early stage of rehabilitation, the support rod 9 can ensure that the leg sleeve 1 6 and the leg sleeve 2 7 are in a fastened connection state to prevent the patient from falling due to knee bending during walking.

[0025] Further improvement, such as Figure 4 As shown, the plug-in rod 14 includes a rod body 18 and a convex ball 19 fixed below the rod body 18 , and the rod body 18 is fixed on the elastic movable plate 13 .

[0026] Further improvement, such as Figure 4As shown, the adjustable card plate is composed of two groups of arc plates 20 arranged symmetrically, and a slot 21 is formed between the two groups of arc plates 20.

According to the depth of the plug-in rod 14 inserted into the adjustable card plate, the purpose of adjusting the tightness between the leg sleeve plate 1 6 and the leg sleeve plate 2 7 is achieved. When the convex ball 19 is located at the inner end of the slot 21, the bending floating between the leg sleeve plate 1 6 and the leg sleeve plate 2 7 is small. When the convex ball 19 is located at the outer end of the slot 21, the bending floating between the leg sleeve plate 1 6 and the leg sleeve plate 2 7 is large.

[0027] Further improvement, such as Figure 5 As shown, the traction assembly includes a housing 22, a drive motor 23, a battery 24, a rotating disk 25, a traction rod 26, a contact rod 27, a limit rod 28 and a vertical rod 29. The housing 22 is fixed to the U-shaped bracket 2. The drive motor 23 is built into the housing 22 and connected to the battery 24 through a line. The power output end of the drive motor 23 is connected to the rotating disk 25. The edge of the rotating disk 25 is connected to the traction rod 26. The traction rod 26 is connected to the traction belt 1. The contact rod 27 and the limit rod 28 are symmetrically installed on the edge of the rotating disk 25. The vertical rod 29 is fixed to the outer On the inner wall of the shell 22, a switch button 30 is provided on the vertical pole 29, and one of the groups of bases 4 is provided with a switch button 2 31. The driving motor 23 drives the rotating disk 25 to rotate. During the rotation, the rotating disk 25 drives the traction rod 26 to rotate synchronously. The traction rod 26 drives the traction belt 1 to adjust the winding. During the winding process, the traction belt 1 is used to pull the patient to take steps. When the traction rod 26 rotates to the switch button 30 on the vertical pole 29, the battery 24 cuts off the power to the driving motor 23, and the rotating disk rotates under the action of the traction force to complete the stepping operation in sequence.

[0028] Specifically, the switch button 1 30 and the switch button 2 31 are both connected to the battery 24 through a line, and the switch button 1 30 and the switch button 2 31 can control the battery 24 to achieve the purpose of turning the drive motor 23 on and off.

[0029] During use: when it is necessary to perform lower limb support rehabilitation training for the patient, the medical staff puts the two sets of leg support adjusters on the patient's lower limbs respectively through the straps 8, and makes the leg sleeve 1 6 and the leg sleeve 2 7 located above and below the knee, and then connects the leg support adjuster to the traction component through the traction belt 1. In the early stage of rehabilitation, when the patient walks, he first lifts the walker body and moves forward. When the walker body falls and contacts the ground, the switch button 2 31 is triggered. At this time, the battery 24 is powered on to drive the motor 23, and the drive motor 23 drives the rotating disk 25 to rotate. During the rotation, the rotating disk 25 drives the traction rod 26 to rotate synchronously. The traction rod 26 drives the traction belt 1 to be wound and adjusted. During the winding process, the traction belt 1 is used to pull the patient to take a step. When the traction rod 26 rotates to the switch button 1 30 on the vertical pole 29, the battery 24 is powered off to drive the motor 23. The rotating disk is in the traction force The traction belt 1 and the support rod 9 are disconnected when the patient can take steps independently in the middle stage of rehabilitation. In the late stage of rehabilitation, the electric push rod 12 is used to adjust the position of the elastic movable plate 13 according to the patient's leg support needs. According to the depth of the plug-in rod 14 inserted into the adjustable card plate, the purpose of adjusting the tightness between the leg sleeve plate 1 6 and the leg sleeve plate 2 7 is achieved. When the convex ball 19 is located at the inner end of the slot 21, the bending floating between the leg sleeve plate 1 6 and the leg sleeve plate 2 7 is small, and the supporting auxiliary effect is greater. When the convex ball 19 is located at the outer end of the slot 21, the bending floating between the leg sleeve plate 1 6 and the leg sleeve plate 2 7 is large, and the supporting auxiliary effect is smaller, which is more suitable for exercising the patient's leg supporting force.
