When working, a patient can sit on it and keep a sitting posture under the action of the support base 5, and then the patch 9 in the electromyographic sensor 7 is placed on the patient's limb muscle parts. When the patient uses the upper limb training mechanism and the lower limb training mechanism for training, the force generated by the limbs can be fed back through the first tension sensor 15 and the second tension sensor 20, and the data of the limb muscles can be fed back through the electromyographic sensor 7. These data are displayed through an external display device, and then the patient's limb rehabilitation status can be assessed based on the data.

[0021] Furthermore, the lower limb training mechanism includes a slide groove 10 provided on the upper end surface of the support block 3, a spring groove 11 provided in the slide groove 10, a slide rod 12 fixedly connected in the slide groove 10, a slider 13 slidably connected on the circumferential surface of the slide rod 12, a push block 14 fixedly connected at the upper end of the slider 13, a first tension sensor 15 fixedly connected in the spring groove 11, a first tension spring 16 fixedly connected at the front end of the first tension sensor 15, and a front end of the first tension spring 16 fixedly connected to the slider 13. During operation, when the patient sits on the support seat 5, the foot pushes the push block 14 forward, and pushing it open will drive the slider 13 to move forward. At this time, the slider 13 will stretch the tension spring. After the tension spring is stretched, the first sensor will record the tension generated by the lower limb training, thereby achieving the effect of recording the lower limb force data while training the lower limbs.

[0022] Furthermore, the upper limb training mechanism includes an installation tube 17 fixedly connected in the support rod 6, a pull tube 18 is slidably connected in the installation tube 17, a pull ring 19 is fixedly connected at the lower end of the pull tube 18, a second tension sensor 20 is fixedly connected in the installation tube 17, a second tension spring 21 is fixedly connected at the lower end of the second tension sensor 20, and the lower end of the second tension spring 21 is fixedly connected to the pull-through. When working, the pull ring 19 is pulled by hand and then force is applied downward. At this time, the pull tube 18 will slide downward in the installation tube 17, and the second tension spring 21 will be stretched. After the second tension spring 21 is stretched, the second tension sensor 20 will record the tension generated by the upper limb training, thereby achieving the effect of recording the upper limb force data while training the upper limbs.

[0023] Furthermore, a sliding hole 22 is provided on the rear end face of the mounting plate 4, and a guide rod 23 is slidably connected in the sliding hole 22. A support plate 24 is fixedly connected to the front end of the guide rod 23. A threaded rod 25 is threadedly connected in the mounting plate 4. The threaded rod 25 is rotatably connected to the support plate 24. When working, by rotating the threaded rod 25 and then through the guiding and limiting action of the guide rod 23, the threaded rod 25 will drive the support plate 24 to adjust the front and rear position, thereby achieving the effect of adjusting the patient's back support point. At this time, when facing patients of different sizes, the position of the support plate 24 can be adjusted so that it can adapt to the position of the lower limb training mechanism and the upper limb training mechanism to make corresponding training assessments.

[0024] Furthermore, a first cotton pad 26 is fixedly connected to the surface of the backrest 24, and a second cotton pad 27 is fixedly connected to the upper end of the support seat 5. During operation, the first cotton pad 26 and the second cotton pad 27 can improve the comfort of the patient during sitting and leaning training.

[0025] Furthermore, a first reinforcing rib 28 is fixedly connected to the upper end of the base 1, and an end of the first reinforcing rib 28 away from the base 1 is fixedly connected to the mounting plate 4, and a second reinforcing rib 29 is fixedly connected to the front end of the mounting plate 4, and an end of the second reinforcing rib 29 away from the mounting plate 4 is fixedly connected to the support rod 6. During operation, the stability of the device during use can be improved through the action of the first reinforcing rib 28 and the second reinforcing rib 29.

[0026] The working principle of the utility model is as follows: through the action of the support seat 5, the patient can sit on it, and at the same time, by rotating the threaded rod 25 and then through the action of the guide limit of the guide rod 23, the threaded rod 25 will drive the backrest 24 to adjust the front and rear position, thereby achieving the effect of adjusting the patient's back support point. At this time, when facing patients of different sizes, the position of the backrest 24 can be adjusted to make it able to adapt to the positions of the lower limb training mechanism and the upper limb training mechanism to make corresponding training assessments, and then the patches 9 in the electromyographic sensor 7 are placed on the patient's limb muscles. At this time, when the foot pushes the push block 14 forward, pushing it open will drive the slider 13 to move forward, and at this time the slider 13 will stretch the tension spring. After the tension spring is stretched, the first sensor will react to the tension generated by the lower limb training The patient holds the pull ring 19 with his hand and then exerts force downward. At this time, the pull tube 18 will slide downward in the mounting tube 17. At this time, the second tension spring 21 will be stretched. After the second tension spring 21 is stretched, the second tension sensor 20 will record the tension generated by the upper limb training, thereby achieving the effect of recording the upper limb force data while training the upper limb. The first tension sensor 15 and the second tension sensor 20 are used to feed back the force and movement amplitude of the limbs. At the same time, the electromyographic sensor 7 is used to feed back the state and positioning of the limb muscles. These data are displayed through an external display device, and then the patient's limb rehabilitation status can be evaluated based on the data.
