As shown in fig. 1, the upper surfaces of the thigh panel 3, the seat panel 4 and the upper body panel 5 are respectively provided with a thigh panel cushion 3a, a seat panel cushion 4a and an upper body panel cushion 5b, so as to increase comfort, and the thigh panel cushion 2d, the thigh panel cushion 3a, the seat panel cushion 4a and the upper body panel cushion 5b are all made of sponge, so as to reduce weight, and the surface is wrapped with breathable elastic fabric, so that the elasticity is breathable.

As shown in figure 1, the shank plate 2, the thigh plate 3, the seat plate 4 and the upper body plate 5 are all made of rectangular stainless steel pipes in a splicing mode, and weight is reduced.

Be equipped with display screen and control button on the controller 6, the display screen can show exercise intensity, sets for rated exercise intensity through control button to reach the number of times of rated exercise intensity when taking exercise by controller 6 to the patient and count.

The using process of the embodiment is as follows: when a patient can actively do leg exercise, the hip of the patient is seated on the seat plate 4, the lower leg of the patient is placed on the lower leg plate 2, the knee of the patient corresponds to the position, hinged to the lower leg plate 2, of the upper leg plate 3, the position, on the herringbone buckle, of the leg binding belt 11 is adjusted, after the length of the leg binding belt 11 is proper, the leg binding belt 11 surrounds the lower leg of the patient, the buckle 11b is inserted into the buckle belt 11a, the lower leg of the patient and the lower leg plate 2 are fixed, the tension spring 10 with proper strength is replaced according to the condition of the patient, rated exercise strength is set for the controller 6, the patient actively enables the lower leg to be folded towards the upper leg, the lower leg plate 2 and the upper leg plate 3 are driven to rotate, one end of the lower leg plate 2 slides along the sliding groove 1c through the sliding pin shaft 2e, the other end of the lower leg plate and the upper leg plate 3 are.

When a patient needs to carry out passive leg exercise, the hip of the patient is seated on the seat plate 4, the lower leg of the patient is placed on the lower leg plate 2, the knee of the patient corresponds to the position of the upper leg plate 3 hinged to the lower leg plate 2, the position of the leg binding belt 11 on the zigzag buckle is adjusted, after the length of the leg binding belt 11 is proper, the leg binding belt 11 is wound around the lower leg of the patient, the buckle 11b is inserted into the buckle belt 11a, the lower leg of the patient is fixed with the lower leg plate 2, all the tension springs 10 are taken down, the first servo motor 12 is started through the controller 6, the time and the speed of the forward rotation and the reverse rotation of the first servo motor 12 are set according to the length of the chute 1C, when the first servo motor 12 rotates forward, the first lead screw 13 is driven to rotate, the C-shaped clamp 18 is driven to be far away from the first servo motor 12 along the first lead screw 13, the C-shaped clamp 18 is driven to be contacted with the movable connecting rod 2C to push, the thigh and the shank of the patient are passively bent and flexed, and the muscle of the leg of the patient is moved; when the first servo motor 12 rotates reversely, the first lead screw 13 is driven to rotate, the first lead screw 13 rotates to drive the C-shaped clamp 18 to be close to the first servo motor 12 along the first lead screw 13, the C-shaped clamp 18 does not apply thrust to the movable connecting rod 2C any more, the lower leg plate 2 is pressed by the gravity of the leg of the patient, slides along the sliding groove 1C through the sliding pin shaft 2e, and is passively exercised once after the limiting block 3b is embedded into the limiting groove 1 b.

When the patient needs to adjust the body position, the medical staff operates the controller 6 to enable the second servo motor 19 to work to drive the second screw rod 20 to rotate, the second screw rod 20 rotates to drive the second screw rod slide block 21 to slide, and the connecting rod 5a can limit the second screw rod slide block 21 to rotate and can drive the upper body plate 5 to rotate when the second screw rod slide block 21 slides to change the angle of the upper body of the patient.

The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modifications made on the basis of the technical scheme according to the technical idea of the present invention fall within the protection scope of the present invention.
