[0044] The disc frame 31 is composed of two disc structures with large and small sizes, and can protect the torsion gear 32 and the transmission gear 37 in the daily state, prevent sundries from entering the inside of the disc frame 31, and affect the meshing effect of the transmission gear 37 and the torsion gear 32, the encoder of the micro motor 38 is controlled by the control panel 15 under the programming code, the rotational speed of the shaft end of the micro motor 38 can be set to multi-stage adjustment, and then the corresponding gear of the micro motor 38 is controlled to be turned on according to the recovery effect of the patient, the transmission gear 37 is driven to rotate to drive the torsion gear 32 to rotate, the rotation of the rotating shaft 33 is controlled, the rotating shaft 33 drives the pedal 35 to rotate in cooperation with the side plate 34, the pedal 35 drives the patient's lower limbs to exercise gradually in cooperation with the restraint 4, the carbon plate 43 is positioned by the rubber block 36, and the carbon plate 43 is guided to be placed at the center position when the carbon plate 43 is placed on the pedal 35, and the inclined surface design of the pedal 35 can position the carbon plate 43 to prevent the carbon plate 43 from sliding sideways when the carbon plate 43 is overlapped on the surface of the pedal 35.

[0045] When the hook plate 47 is inserted from the top end of the pedal 35, the spring B 393 can push the clamping block 391 to control the clamping block 391 to be inserted into the clamping groove at the bottom end of the hook plate 47, so as to ensure the quick connection of the carbon plate 43 and the pedal 35 and improve the convenience of the installation operation, the design of the pull ring 394 can control the movement of the connecting shaft 392 by pulling the pull ring 394, the clamping block 391 is controlled to be separated from the clamping groove of the hook plate 47, and the hook plate 47 is pulled out upward after sliding to the right, so that the carbon plate 43 and the pedal 35 are separated.

[0046] The arc structure of the sheath 41 can conveniently wrap and suspend the lower leg of the patient. The memory cotton composite layer in the sheath 41 can improve the wrapping comfort. After the binding belt 46 is wrapped around the outside of the sheath 41 and tightened, the end of the binding belt 46 is inserted into the fence frame at one end and then preliminarily fixed. The clamping pin 48 is inserted into the hole slot of the binding belt 46 to reinforce and lock, thereby reducing the probability of the sheath 41 falling off during the patient's movement. The slider 492 moves in the sliding groove of the guide plate 493. The end of the connecting belt 491 moves along with the slider 492 to pull the carbon plate 43. The angle between the carbon plate 43 and the sheath 41 is adjusted, so that the patient's foot and wrist are kept within a safe angle for exercise. The sliding groove of the guide plate 493 is provided with a tooth groove.

[0047] The lifting rope 26 extends from the bottom end of the pay-off wheel 24, moves upward through the bottom end of the guide wheel A 23, and then falls after being wound on the surface of the guide wheel B 25. The lifting rope 26 assists in suspending the sheath 41, dynamically reduces the leg load according to the degree of muscle strength recovery of the patient, and quickly suspends the sheath 41 by using the quick insertion type butt joint between the plug-in disc 271 and the sleeve disc 272. During insertion, the spring force of the spring A 274 cooperates with the clamping plate 275 to enable the clamping plate 275 to be clamped on the left and right sides of the sleeve disc 272. The inclined surface self-locking structure of the quick connector 27 can bear ≥200 kg, which prevents falling during training and ensures the safety of the patient during exercise. The fan-shaped protrusions on the surface of the plug-in disc 271 can be in contact with the end face of the insertion slot opening in the sleeve disc 272, preventing the plug-in disc 271 from shaking after insertion.

[0048] Working principle: according to the attached Figure 4 and the attached Figure 5As shown, during use, the sheath 41 is first placed on the patient's calf wrist area, so that the carbon plate 43 supports the patient's foot sole, the restraint belt 44 restrains the patient's instep, and the end of the restraint belt 46 is sewn to the surface of the sheath 41. The restraint belt 46 is pulled through the fence frame at the other end of the restraint belt 46. The clamping pin 48 is toggled to insert the clamping pin 48 into the clamping hole of the restraint belt 46. As the restraint belt 46 contracts, the sheath 41 can wrap and protect the patient's calf area to prevent the sheath 41 from rubbing against the thigh due to bending of the calf. The silicone skirt 45 design on the left side of the sheath 41 can reduce Low friction improves the comfort of calf movement. According to the degree of ankle bending, the connecting belt 491 can be pulled to drive the slider 492 to move in the guide groove of the guide plate 493. When the connecting belt 491 is pulled to a certain degree of tightness, the patient's foot is adjusted to a comfortable level according to the patient's feeling. By rotating the threaded pin 494, the shaft end of the threaded pin 494 rotates and can resist and squeeze the inner wall of the guide groove of the guide plate 493. The rubber block at the end of the shaft of the threaded pin 494 is deformed after being squeezed and engages with the tooth groove of the inner wall of the guide groove of the guide plate 493, ensuring the stability of the connecting belt 491 after adjustment.

[0049] Secondly, according to the attached Figure 1 With attached Figure 2 As shown, through holes are provided on both end surfaces of the bottom of the H base 11, which can facilitate the installation of universal wheels, making the H base 11 movable. By moving the H base 11 to the end of the bed, the movable cover 13 slides on the surface of the column 12, thereby changing the height of the suspension arm 16. After adjustment, the fixing bolt 14 can be rotated to make the shaft end of the fixing bolt 14 contact the corresponding groove of the column 12. The telescopic arm 17 is extended and retracted. During operation, the telescopic arm 17 is pulled and moved inside the suspension arm 16, thereby changing the position of the driving member 3 so that the pedal 35 of the driving member 3 can adapt to the patient's feet. Figure 4 With attached Figure 6 As shown, after the protective cover 41 and the carbon plate 43 are installed on the patient's foot, the hook plate 47 is engaged with the slot of the pedal 35. As the horizontal plate end of the hook plate 47 moves, the elastic force of the spring B393 pushes the card block 391, and the card block 391 is controlled to dock with the slot at the bottom of the horizontal plate end of the hook plate 47 during movement. At this time, the rubber block 36 can provide auxiliary support for both sides of the bottom end of the carbon plate 43 to ensure the stability of the placement of the carbon plate 43.

[0050] According to the attached Figure 7 With attached Figure 8As shown, when the calf strength of the patient is difficult to lift for a long time, the insert disc 271 is inserted from top to bottom in the sleeve disc 272, the spring A 274 is sent to the clamping plate 275 by the elastic force, so that the clamping plate 275 can move from the left and right two side holes of the sleeve disc 272, and then the clamping of the sleeve disc 272 and the insert disc 271 is completed, the top end of the ring belt 273 is connected with the top corner of the sheath 41, and the sheath 41 can be suspended, thereby reducing the exercise burden of the patient, and the suspension can be gradually cancelled according to the recovery stage of the patient.
