[0023] Limit blocks 17 are fixedly arranged on the inner walls on both sides of the lifting cylinder 4, and limit sliders 18 are slidably installed in the vertical direction on the inner walls on both sides of the lifting cylinder 4 located below the limit blocks 17, and the limit sliders 18 are in movably contact with the limit blocks 17; an electric telescopic rod 10 is fixedly installed on the top inner wall of the sleeve cavity 501, and the output end of the electric telescopic rod 10 is fixedly connected with a movable disk 11, and the bottom ends of the movable disk 11 are fixedly connected with connecting rods 12, and a fixed plate 15 is fixedly installed in the sleeve cavity 501 located below the movable disk 11, and the bottom end of the connecting rod 12 movably penetrates to the bottom of the fixed plate 15 and is fixedly connected with a movable ring 13, and the bottom of the fixed plate 15 is fixedly connected with a fixed rod 16, and the movable ring 13 is movably sleeved on the fixed rod 16; the bottom end of the fixed rod 16 also movably penetrates into the lifting cylinder 4, and a tension spring 14 sleeved on the fixed rod 16 is fixedly connected between the top of the lifting cylinder 4 and the movable ring 13.

[0024] In this example, the tension spring 14 is always in a stretched state; a through hole is provided on the fixing plate 15, and the connecting rod 12 moves along the vertical direction to pass through the through hole.

[0025] In this example, the spacing adjustment mechanism includes two slide grooves 601 arranged on the inner wall of the bottom of the mounting frame 6, and the same screw rod 8 is rotatably installed in the two slide grooves 601. Slide seats 9 are also slidably installed in the two slide grooves 601, and the screw rod 8 is connected to the two slide seats 9 by threads respectively; a stepper motor 7 is fixedly installed on the right outer inner wall of the slide groove 601 through a mounting groove, and the output end of the stepper motor 7 is fixedly connected to the right end of the screw rod 8.

[0026] In this example, external threads 801 are respectively provided on the screw rods 8 located in the two slide grooves 601, and the thread directions of the two external threads 801 on the screw rod 8 are arranged in opposite directions; screw holes 901 are respectively provided on the two slide seats 9, and the screw rods 8 are respectively threadedly connected to the two screw holes 901.

[0027] A controller 19 is also provided on the front of the mounting frame 6 , and the controller 19 is electrically controlled and connected to the retractable motor 301 , the stepping motor 7 , and the electric telescopic rod 10 , respectively.

[0028] like Figure 1-3 As shown, when in use: the device is installed in the patient ward who needs respiratory muscle recovery. When installing, the mounting frame 6 is fixed on the top of the wall just above the bed and close to the bedside, so that it is convenient for the patient to train independently; and the device needs to be used with a ventilator for internal auxiliary training during use. When training, the patient needs to sit, then hold the two bracelets 1 with both hands and lift them up, and pull the two bracelets 1 to lie flat on the bed. In the process of lying down, the two bracelets 1 are used to perform ups and downs movements on the patient's hands and upper limbs, so that the upper limbs can effectively exercise the chest and lung muscles during the exercise, and at the same time cooperate with the ventilator for internal auxiliary training, which can increase the speed of the patient's respiratory muscle recovery. When the hand ring 1 is pulled downward, the pull rope 2, the U-shaped seat 3, and the lifting cylinder 4 will be driven to move downward and the tension spring 14 will be stretched; when the hand ring 1 is not pulled, the hands and upper limbs on the hand ring 1 can be automatically moved upward under the reset action of the tension spring 14. Finally, through the ups and downs of the patient's upper limbs, the chest and lung muscles can be effectively exercised, and the recovery speed of the patient's respiratory muscles can also be improved. In use, the movable disk 11, the connecting rod 12, and the movable ring 13 can be adjusted upward or downward by the extension and contraction of the output end of the electric telescopic rod 10. When the movable ring 13 is adjusted upward, the movable ring 13 can further stretch and deform the tension spring 14. In this way, when the pull rope 2, the U-shaped seat 3, and the lifting cylinder 4 are subsequently pulled down by the hand ring 1, the tension spring 14 will require greater force to stretch the tension spring 14 during the downward stretching, so that the tension required for the training of the hand ring 1 can be increased; on the contrary, when the movable ring 13 is downward During adjustment, the movable ring 13 can loosen the tension spring 14, so that when the wristband 1 is used to pull the traction rope 2, the U-shaped seat 3 and the lifting cylinder 4 and stretch the tension spring 14, a smaller force will be used to stretch the tension spring 14, so that the tension required by the wristband 1 can be reduced. Finally, it is convenient for people to adjust the tension required by the wristband 1 according to actual training needs, so as to meet the use needs of different patients, greatly reducing the limitations in use, and improving the scope of application. The structure is simple and easy to adjust and use. During adjustment, the retractable motor 301 can also be used to drive the retractable wheel 302 to rotate forward or reverse, so that the length of the traction rope 2 on the retractable wheel 302 can be adjusted. In this way, by adjusting the length of the traction rope 2, the height of the wristband 1 can be adjusted.

[0029] In addition, by setting up a spacing adjustment mechanism, the screw 8 can be driven by the stepping motor 7 to rotate forward and reverse. Since the thread directions of the two external threads 801 on the screw 8 are set in opposite directions, the two slides 9 can be made to move closer to or away from each other through the screw holes 901 on the two external threads 801 of the screw 8. When the two slides 9 move, they also drive the stand 5, the lifting cylinder 4, the U-shaped seat 3, the pull rope 2, and the distance between the bracelet 1 on both sides to be adjusted, so that the distance between the two bracelets 1 can be adjusted according to actual training needs, further improving practicality.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
