[0033] The cooperative component 7 includes a cooperative rope 701 connected to the lower limb exercise component 4 and the upper limb exercise component 5. The cooperative rope 701 transmits kinetic energy so that the lower limb exercise component 4 can drive the upper limb exercise component 5, or the upper limb exercise component 5 drives the lower limb exercise component 4, playing an auxiliary role.

[0034] As can be seen from the above, when exercising, the patient sits on the chair 2, with the patient's legs placed on the lower limb exercise component 4, and the palms of the hands hold the upper limb exercise component 5. Since the patient has just recovered and has limited physical strength, during exercise, the lower limb exercise component 4 can drive the upper limb exercise component 5, or the upper limb exercise component 5 can drive the lower limb exercise component 4, so that the party that actively exerts force can reduce the pressure of the other party, and the upper and lower limbs can be exercised at the same time, thereby improving the coordination of the muscles of the whole body.

Then, when the exercise plate 402 rotates, the inclination angle of the accommodating tube 404 and the telescopic rod 405 changes, and at the same time, the total length of the accommodating tube 404 and the telescopic rod 405 changes. A spring 407 is sleeved on the circumference of the telescopic rod 405, and the telescopic rod 405 is connected to a baffle 408. When the total length of the accommodating tube 404 and the telescopic rod 405 changes, the baffle 408 will be driven to move, and the movement of the baffle 408 will drive the spring 407 to deform, thereby providing a certain resistance to the rotation of the exercise plate 402, thereby ensuring the intensity of the exercise.

[0038] As attached Figure 5 As shown, further, threads are provided on the circumferential side of the telescopic rod 405, and the telescopic rod 405 is threadedly connected to the baffle 408 through the threads. By rotating the baffle 408, the position of the baffle 408 on the telescopic rod 405 can be changed, and then the compression strength of the spring 407 can be changed. The resistance of the rotation of the exercise plate 402 can be adjusted according to the progress, and the two ends of the spring 407 are respectively against the accommodating tube 404 and the baffle 408.

[0040] As attached Figure 1 To Attachment Figure 2 As shown, further, the upper limb exercise component 5 also includes a top plate 505 fixedly connected to the support frame 3, and the top plate 505 is provided with a shaking groove 506, and a limiting rod 507 is movably connected in the shaking groove 506, and the limiting rod 507 cooperates with the sliding groove to limit the movement of the lifting plate 501, and the upper surface of the limiting rod 507 is fixedly connected to the limiting plate 508, wherein the limiting plate 508 is used to prevent the limiting rod 507 from separating from the shaking groove 506, and the lower surface of the limiting rod 507 is fixedly connected to the upper surface of the lifting plate 501, and both hands alternately pull down the vertical rod 503 through the handle 504, and the vertical rod 503 drives the lifting plate 501 to rotate with the connection between the lifting plate 501 and the cooperative rope 701 as the center point, and the upper limbs complete the alternating pulling-down action.

[0041] As attached Figure 1 As shown, further, the cross-section of the limiting rod 507 is square, the width of the shaking groove 506 is equal to the width of the limiting rod 507, the limiting rod 507 is limited in the width direction of the shaking groove 506, the length of the shaking groove 506 is greater than the length of the limiting rod 507, and the limiting rod 507 can be offset in the shaking groove 506 along the length direction of the shaking groove 506.

[0042] As attached Figure 3 As shown, further, the first pulley 702 is fixedly installed on the support frame 3, the second pulley 703 and the third pulley 704 are fixedly installed on the upper surface of the top plate 505, and the end of the cooperation rope 701 away from the lifting plate 501 passes through the third pulley 704, the second pulley 703 and the first pulley 702 in sequence and is fixedly connected to the exercise plate 402. When the lifting plate 501 is lifted or lowered, the exercise plate 402 is driven to rotate through the cooperation rope 701. When the exercise plate 402 rotates, the lifting plate 501 is driven to lift or lower through the cooperation rope 701, thereby performing exercise synchronously.

[0043] As can be seen from the above, when exercising, the patient sits on the seat 2, the patient's legs are placed on the exercise board 402 and fixed by straps, and the patient's palms hold the handles 504;

[0044] The patient's leg force drives the exercise board 402 to rotate and swing. When the exercise board 402 rotates and swings, the inclination angles of the accommodating tube 404 and the telescopic rod 405 change to cooperate with the rotation of the exercise board 402. At the same time, the total length of the accommodating tube 404 and the telescopic rod 405 changes. At this time, the baffle 408 moves with the telescopic rod 405 and deforms the spring 407, thereby providing a certain resistance to the rotation of the exercise board 402 to ensure the intensity of the exercise. The baffle 408 is rotated, and the thread changes the position of the baffle 408 on the telescopic rod 405, thereby changing the compression strength of the spring 407, so that the resistance to the rotation of the exercise board 402 can be adjusted according to the progress of the exercise.

[0045] The patient's hands exert force to perform alternating or synchronous pulling-down movements. When performing alternating pulling-down movements, the upper hand alternately pulls down the vertical rod 503 through the handle 504, and the vertical rod 503 drives the lifting plate 501 to rotate and swing around the connection between the lifting plate 501 and the coordination rope 701 as the center point. At the same time, the limit rod 507 rotates and deviates in the sliding groove along the length direction of the shaking groove 506; when performing a synchronous pulling-down movement, both hands synchronously pull the vertical rod 503 downward through the handle 504, and the downward movement of the vertical rod 503 drives the lifting plate 501 to move downward, and the lifting plate 501 pulls the coordination rope 701, and the coordination rope 701 transmits power to the exercise plate 402, pulling the exercise plate 402 to rotate. When the exercise plate 402 rotates, the lifting plate 501 will be driven to rise and fall through the coordination rope 701, thereby synchronously exercising to improve the coordination of the whole body's muscle groups, and the exercise intensity of the upper limbs or lower limbs can be reduced by the other party, thereby reducing the difficulty of exercise for patients who have just recovered.

[0048] As attached Figure 6 As shown, specifically, the lifting sleeve 604 is fixedly connected to the lifting plate 501, and two groups of auxiliary components 6 are provided to ensure the smooth lifting of the lifting plate 501. The lifting rod 603 is eccentrically arranged on the disc 602, and the lifting rod 603 performs a circular motion when the disc 602 rotates.

[0049] As can be seen from the above, the auxiliary motor 601 drives the disc 602 to rotate, and the rotation of the disc 602 drives the lifting rod 603 to make a circular motion. During the movement of the lifting rod 603, it drives the lifting sleeve 604 to move up and down, and then drives the lifting plate 501 to move up and down. The auxiliary component 6 drives the lifting plate 501 to move up and down to reduce the intensity of training, making the training intensity more suitable for patients who have just recovered.
