The stretching training assemblies 2 are arranged on both sides of the adjustment assembly 1, and the pulling force increasing assembly 3 is arranged in the inner cavity of the stretching training assembly 2. The connecting rod 12 is fixedly installed on the top of the counterweight base 11, the motors 16 are fixedly installed on both sides of the top of the connecting rod 12, the first chutes 13 are opened on both sides of the connecting rod 12, the first sliders 14 slide inside the first chutes 13, the connecting columns 21 are fixedly installed around the upper part of the mounting frame 23, the top plate 22 is fixedly installed on the top of the connecting column 21, and the positioning seat 24 is fixedly installed at the center of the inner cavity of the mounting frame 23;

[0021] More specifically, the top plate 22 is supported and fixed by setting the connecting column 21. When in use, when the patient is shorter or taller, the motor 16 can be turned on. According to the requirements of the use scenario, at this time, the motor 16 drives the threaded rod 15 to rotate, so that the first slider 14 drives the stretching training component 2 and the tension increasing component 3 to move, so as to adjust to a height suitable for the patient. During training, the patient holds the pull handle 29. At this time, under the action of force, the pull handle 29 drives the positioning plate 26 and the positioning column 31 to move downward. Then, under the action of the third spring 35, the second spring 28 and the first spring 27, a pulling force in the opposite direction is generated, so as to train the upper limbs of the patient. When it is necessary to reduce the training intensity, rotate the threaded frame 37 to release the control of the positioning column 31, so that the pulling force is weakened, which has the advantage of convenient adjustment and use.

[0022] In some embodiments, the threaded rod 15 rotates through the thread inside the first slider 14. The output shaft of the motor 16 penetrates into the inner cavity of the first chute 13 and is fixedly connected to the top of the threaded rod 15. The limit seats 32 are fixedly installed on both sides of the bottom of the top plate 22. More specifically, by setting the motor 16 to drive the threaded rod 15, the position of the first slider 14 is indirectly adjusted.

[0023] In some embodiments, the slide rod 25 slides in the inner cavity of the positioning seat 24. The pull handle 29 is fixedly installed at the bottom of the slide rod 25. The third spring 35 is fixedly installed at the top of the inner cavity of the limit seat 32. More specifically, by setting the slide rod 25 to limit the positions of the positioning plate 26 and the annular seat 36, it is prevented that the positioning plate 26 and the annular seat 36 shake during the moving process.

[0024] In some embodiments, the relatively far sides of the first slider 14 are fixedly connected to the relatively close sides of the mounting frame 23. The second springs 28 are fixedly installed on both sides of the top of the pull handle 29. The positioning column 31 is fixedly installed at the bottom of the third spring 35. More specifically, by setting the second spring 28 and the third spring 35 to generate a pulling force, the upper limbs of the patient are trained.

[0025] In some embodiments, the top of the second spring 28 is fixedly connected to the bottom of the positioning seat 24. The first springs 27 are fixedly installed on both sides of the top of the positioning seat 24. The second chutes 34 are opened on both sides of the inner cavity of the limit seat 32. More specifically, by setting the second chutes 34 to limit the second slider 33, it is prevented that the second slider 33 shakes during the moving process. By setting the first spring 27, the positioning plate 26 is reset.

[0026] In some embodiments, the positioning plate 26 is fixedly installed on the top of the first spring 27. The bottom of the positioning plate 26 is fixedly connected to the top of the sliding rod 25. The second slider 33 slides in the inner cavity of the second chute 34. More specifically, by providing the second slider 33, the positioning post 31 is limited to prevent the positioning post 31 from shaking during movement.

[0027] In some embodiments, the relatively close sides of the second slider 33 are fixedly connected to both sides of the positioning post 31. The annular seats 36 are fixedly installed on both sides of the positioning plate 26. The threaded frame 37 is rotationally threaded inside the annular seat 36. The relatively close side of the threaded frame 37 penetrates into the inside of the positioning post 31 and extends to the outside of the annular seat 36. More specifically, by providing the threaded frame 37, it is convenient to fix the connection between the annular seat 36 and the positioning post 31.

[0028] Working principle:

[0029] Step 1: When in use, when the patient is shorter or taller, the motor 16 can be turned on. According to the requirements of the usage scenario, at this time, the motor 16 drives the threaded rod 15 to rotate, so that the first slider 14 drives the positions of the stretching training assembly 2 and the tension increasing assembly 3 to move, so as to adjust to a height suitable for the patient.

[0030] Step 2: During training, the patient holds the pull handle 29. At this time, under the action of force, the pull handle 29 drives the positioning plate 26 and the positioning post 31 to move downward. Then, under the action of the third spring 35, the second spring 28 and the first spring 27, a pulling force in the opposite direction is generated, so as to train the patient's upper limbs. When it is necessary to reduce the training intensity, rotate the threaded frame 37 to release the control of the positioning post 31, so that the pulling force weakens, which has the advantage of convenient adjustment and use.
