Description

Technical Field

[0001] The present invention relates to the technical field of shoulder joint rehabilitation training equipment, and in particular to a multifunctional medical shoulder joint rehabilitation trainer and a method for using the same. Background Art

[0002] The shoulder joint is composed of the glenoid cavity of the scapula and the head of the humerus. Among current rehabilitation methods, exercise rehabilitation training is one of the most effective. The upper limb is a vital functional unit in people's daily lives, and upper limb dysfunction, particularly in the shoulder joint, is a common problem. Because the shoulder joint supports the movement of the entire arm, it is extremely important for human activity. Rapid recovery from shoulder joint disorders, a common problem in modern society, requires the effective use of rehabilitation training devices.

[0003] Among them, in shoulder joint rehabilitation training, the back muscles of the rotator cuff muscle group are an important training position. Conventional training methods often require patients to lie on the bed and try to raise their arms back to the back. In the actual application of this method, the arms of shoulder joint patients are mostly weak. After the patient lies down, the arm strength will make it difficult to raise the arms back, and it is difficult to achieve the training effect. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a multifunctional medical shoulder joint rehabilitation trainer, comprising a mounting plate, a side wall of the mounting plate being fixedly connected to a strap, a top of the mounting plate being fixedly connected to a fixing rod, a side wall of the fixing rod being fixedly connected to two mounting rods, and ends of the two mounting rods away from the strap being fixedly connected to a fixing frame; The tightening mechanism includes a fixed plate fixedly connected to the top of the fixed frame, the top of the fixed plate is rotatably connected to the take-up wheel, and the bottom of the take-up wheel is fixedly connected to a vortex spring; The training mechanism includes a slide rail fixedly connected to the side wall of the fixed plate, a threaded slider is slidably connected to the inner wall of the slide rail, a cylindrical rod is slidably connected to the inner wall of the threaded slider, a winding wheel is fixedly connected to the top of the cylindrical rod, a metal wire is fixedly connected to the inner wall of the take-up wheel, and a pull ring is fixedly connected to the end of the metal wire away from the take-up wheel. In order to solve the problem that the arm strength of patients with periarthritis of the shoulder will be difficult to perform arm reverse lift training after lying down, a pull ring and a take-up wheel are provided inside the equipment. When in use, the patient installs the strap around the waist, ensures that the installation plate is on the back, and ensures that the tightening mechanism and the training mechanism are on the shoulders of the person. At this time, the patient bends the elbow and inserts the fingers Inside the pull ring, the arm is straightened by pulling outward. After the arm is straightened, the patient raises the arm toward the back. At this time, due to the outward pulling of the metal wire, the take-up wheel and the winding wheel will rotate. When the take-up wheel rotates, it will apply a squeezing force to the vortex spring at the bottom. The vortex spring accumulates mechanical power, and the reaction force generated by the mechanical power will continue to increase with the outward length of the metal wire, thereby increasing the pressure on the back muscles of the rotator cuff when the patient expands his chest, thereby improving the exercise effect of this position. Through the application of the above components, the patient's prone position, supporting and other actions before training are reduced, which causes excessive shoulder pressure and affects the effect of rehabilitation training.

[0005] Preferably, the bottom of the cylindrical rod is fixedly connected to a threaded rod, the outer wall of the threaded rod is meshed with the inner wall of the threaded slider, the top of the threaded slider is fixedly connected to a vortex spring 2, and the bottom of the slide rail is fixedly connected to a correction component.

[0006] Preferably, the training mechanism also includes a metal wire correction plate fixedly connected to the top of the slide rail, the end of the vortex spring 2 away from the threaded slider is fixedly connected to the bottom of the winding wheel, the inner wall of the through hole of the metal wire correction plate is slidably connected to the outer wall of the metal wire, and the end of the vortex spring 1 away from the take-up wheel is fixedly connected to the top of the fixed plate.

[0007] Preferably, the correction component includes a telescopic rod fixedly connected to the bottom of the slide rail, the end of the telescopic rod away from the slide rail is fixedly connected to the slide rail, the bottom of the slide rail is fixedly connected to a hydraulic box, the bottom of the hydraulic box is connected with several hydraulic telescopic tubes, the bottom of the hydraulic telescopic tube is fixedly connected to a rubber block. When the threaded rod rotates along the inner wall of the threaded slider, when the threaded rod moves downward to the lowest end, the threaded rod will no longer contact the inner wall of the threaded slider. At this time, the cylindrical rod is inside the threaded slider, and the threaded rod will no longer move downward. In addition, the hydraulic telescopic tube is elastic, so that the device can accommodate patients of various body shapes, avoiding excessive differences in patient body shapes, causing the correction component to exert excessive pressure on the patient's shoulders, resulting in excessive shoulder pressure and damage to the shoulders.

[0008] Preferably, the correction component also includes a sliding tube slidably connected to the inner wall of the sliding rail, the end of the threaded rod away from the cylindrical rod is rotatably connected to the inner wall of the sliding tube, and a push-back component is fixedly connected to the side wall of the fixed rod. When the above-mentioned metal wire is extended outward, it will drive the wire-taking wheel and the winding wheel to rotate, and the rotation of the winding wheel will drive the bottom cylindrical rod and the threaded rod to rotate synchronously. The rotation of the threaded rod will rotate along the inner part of the threaded slider. During the rotation of the threaded rod, it will be affected by the internal thread of the threaded slider and will gradually move downward, showing a Figure 6 As shown, the threaded rod drives the sliding rail and the hydraulic box downward through the sliding tube, and the hydraulic box drives multiple hydraulic telescopic tubes and the rubber block downward, and forces the rubber block 1 to contact the patient's shoulders. The contact of multiple hydraulic telescopic tubes with the shoulders will apply a downward pressure on the patient's shoulders. Through the application of the above components, when the patient stretches outward, the rubber block 1 and the hydraulic telescopic tube will compress the patient's shoulders, keeping the patient's shoulders in a state of sinking. When the patient pulls downward, he or she will avoid applying force outward, causing the patient to shrug his or her shoulders and transfer the exercise force to other positions, affecting the training effect of the equipment.

[0009] Preferably, the back pushing assembly includes an air pressure slide groove provided at the side wall of the fixed rod, a piston plate is slidably connected to the inner wall of the air pressure slide groove, a push plate is fixedly connected to the side wall of the piston plate, and a rubber block 2 is fixedly connected to one end of the push plate away from the piston plate. Utilizing the characteristic of the downward movement of the above-mentioned hydraulic telescopic tube, a rubber block 2 and a transmission tube are provided inside the equipment. When the hydraulic telescopic tube is compressed and contracted, due to the reduction in the internal space of the hydraulic telescopic tube, the solution inside the hydraulic telescopic tube will pass through the hydraulic box to the inside of the transmission tube, and then be transmitted to the inside of the air pressure slide groove through the transmission tube. As the solution inside the air pressure slide groove increases, the piston plate will slide outward along the inner wall of the air pressure slide groove and push the push plate, the rubber block 2 and the patient's back, forcing the patient's back to straighten forward, ensuring the stable force of the rotator cuff muscles of the back, and avoiding the patient's arms exerting force forward, causing the back to bend downward, causing the patient to have an irregular posture during training, affecting the training efficiency.

[0010] Preferably, the push-back assembly also includes a transmission tube that is connected to the side wall of the fixed rod, and the end of the transmission tube away from the fixed rod is connected to the side wall of the hydraulic box. In order to solve the problem that the patient's arm will produce a large rotation during training, a sliding rail and a sliding tube are provided inside the equipment. When the patient's arm is raised to the back, the winding wheel will drive the cylindrical rod and the threaded slider to move horizontally along the inner wall of the slide rail synchronously to avoid the pull wire being too long and the angle between the metal wire and the top pull wire part being too large, resulting in excessive resistance to the metal wire when stretched, thereby increasing the patient's training strength. Through the application of the above-mentioned components, the influence of the angle on the pulling force is reduced, and a large change in the pulling force occurs.

[0011] A method for using a multifunctional medical shoulder joint rehabilitation trainer includes the following steps: S1: When in use, the patient installs the straps around the waist, ensures that the mounting plate is on the back, and ensures that the tightening mechanism and the training mechanism are on the shoulders; S2: The patient bends his elbow, inserts his fingers into the pull ring, and straightens his arm by pulling it outward. After straightening his arm, the patient raises his arm back to his back. At this time, the wire is pulled outward, causing the take-up wheel and the winding wheel to rotate. The rotation of the take-up wheel applies a squeezing force to the vortex spring at the bottom. S3: The vortex spring accumulates mechanical power, and the reaction force generated by the mechanical power will continue to increase with the length of the metal wire abduction, thereby increasing the pressure on the back muscles of the rotator cuff when the patient expands his chest.

[0012] The present invention has the following beneficial effects: (1) The present invention aims to solve the problem that patients with periarthritis of shoulder cannot lift their arms after lying down. A pull ring and a take-up wheel are provided inside the device. When in use, the patient installs the strap on the waist and ensures that the mounting plate is on the back and that the tightening mechanism and the training mechanism are on the shoulders. At this time, the patient bends the elbow and inserts the fingers into the pull ring. By pulling outward, the arm is straightened. After the arm is straightened, the patient raises the arm back to the back. At this time, due to the outward pulling of the metal wire, the take-up wheel and the winding wheel will rotate. When the take-up wheel rotates, it will apply a squeezing force to the vortex spring at the bottom. The vortex spring accumulates mechanical power, and the reaction force generated by the mechanical power will continue to increase with the length of the metal wire. When the patient expands the chest, the pressure on the back muscles of the rotator cuff muscle group is increased, thereby improving the training effect of this position. By using the above components, the patient can reduce the excessive pressure on the shoulders caused by the actions of lying down and supporting before training, thereby affecting the effect of rehabilitation training.

[0013] (2) The present invention utilizes the above-mentioned metal wire to extend outward, which will drive the take-up wheel and the winding wheel to rotate. The rotation of the winding wheel will drive the bottom cylindrical rod and the threaded rod to rotate synchronously. The threaded rod will rotate along the inside of the threaded slider. During the rotation of the threaded rod, it will be affected by the internal threads of the threaded slider and will gradually move downward, showing the following Figure 6 As shown, the threaded rod drives the sliding rail and the hydraulic box downward through the sliding tube, and the hydraulic box drives multiple hydraulic telescopic tubes and the rubber block downward, and forces the rubber block 1 to contact the patient's shoulders. The contact of multiple hydraulic telescopic tubes with the shoulders will apply a downward pressure on the patient's shoulders. Through the application of the above components, when the patient stretches outward, the rubber block 1 and the hydraulic telescopic tube will compress the patient's shoulders, keeping the patient's shoulders in a state of sinking. When the patient pulls downward, he or she will avoid applying force outward, causing the patient to shrug his or her shoulders and transfer the exercise force to other positions, affecting the training effect of the equipment.

[0014] (3) The present invention utilizes the characteristic of the hydraulic telescopic tube moving downward, and a rubber block 2 and a transmission tube are provided inside the device. When the hydraulic telescopic tube is compressed and contracted, the internal space of the hydraulic telescopic tube is reduced, and the solution inside the hydraulic telescopic tube will pass through the hydraulic box to the inside of the transmission tube, and then be transmitted to the inside of the air pressure chute through the transmission tube. As the solution inside the air pressure chute increases, the piston plate will slide outward along the inner wall of the air pressure chute, and push the push plate, the rubber block 2 and the patient's back, forcing the patient's back to straighten forward, ensuring the stable force of the rotator cuff muscles of the back, and avoiding the patient's arms exerting force forward, causing the back to bend downward, causing the patient to have an irregular posture during training, affecting the training efficiency.

[0015] (4) The present invention addresses the problem that the patient's arm will rotate significantly during training. A sliding rail and a sliding tube are provided inside the device. When the patient raises his arm to his back, the winding wheel will drive the cylindrical rod and the threaded slider to move horizontally along the inner wall of the sliding rail synchronously, so as to avoid the pull wire being too long and the angle between the metal wire and the top pull wire part being too large, resulting in excessive resistance to the metal wire during stretching, thereby increasing the patient's training strength. By applying the above components, the influence of the angle on the pulling force is reduced, and a large change in the pulling force occurs. In addition, when the threaded rod rotates along the inner wall of the threaded slider, when the threaded rod moves downward to the lowest end, the threaded rod will no longer contact the inner wall of the threaded slider. At this time, the cylindrical rod is inside the threaded slider and will no longer move downward. In addition, the hydraulic telescopic tube is flexible, so that the device can be adapted to patients of various body types, avoiding excessive differences in patient body types, resulting in excessive pressure on the patient's shoulders by the correction component, resulting in excessive pressure on the shoulders and damage to the shoulders.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] For example 1, please refer to Figure 1 - Figure 5 The present invention is a multifunctional medical shoulder joint rehabilitation trainer, comprising a mounting plate 1, a strap 11 fixedly connected to the side wall of the mounting plate 1, a fixing rod 12 fixedly connected to the top of the mounting plate 1, two mounting rods 13 fixedly connected to the side wall of the fixing rod 12, and a fixing frame 14 fixedly connected to one end of the two mounting rods 13 away from the strap 11; The tightening mechanism 2 includes a fixed plate 21 fixedly connected to the top of the fixed frame 14, a take-up wheel 22 is rotatably connected to the top of the fixed plate 21, and a vortex spring 23 is fixedly connected to the bottom of the take-up wheel 22; The training mechanism 3 includes a slide rail 31 fixedly connected to the side wall of the fixed plate 21, a threaded slider 32 is slidably connected to the inner wall of the slide rail 31, a cylindrical rod 33 is slidably connected to the inner wall of the threaded slider 32, a winding wheel 34 is fixedly connected to the top of the cylindrical rod 33, a metal wire 35 is fixedly connected to the inner wall of the take-up wheel 22, and a pull ring 37 is fixedly connected to the end of the metal wire 35 away from the take-up wheel 22. In order to solve the problem that the arm strength of patients with periarthritis of the shoulder will be difficult to perform arm reverse lift training after lying down, a pull ring 37 and a take-up wheel 22 are provided inside the equipment. When in use, the patient installs the strap 11 on the waist, ensures that the mounting plate 1 is on the back, and ensures that the tightening mechanism 2 and the training mechanism 3 are on the shoulders of the person. At this time, the patient passes Bend the elbow, insert the fingers into the pull ring 37, and straighten the arm by pulling outward. After the arm is straightened, the patient raises the arm toward the back. At this time, due to the outward pulling of the metal wire 35, the take-up wheel 22 and the winding wheel 34 will rotate. When the take-up wheel 22 rotates, it will apply a squeezing force to the vortex spring 23 at the bottom. The vortex spring 23 accumulates mechanical power, and the reaction force generated by the mechanical power will continue to increase with the outward length of the metal wire 35, thereby increasing the pressure on the back muscles of the rotator cuff muscle group when the patient expands his chest, thereby improving the exercise effect of this position. Through the application of the above components, the patient's actions such as lying down and supporting before training are reduced, which causes excessive shoulder pressure and affects the effect of rehabilitation training.

[0021] For example 2, please refer to Figure 6 - Figure 9 The present invention is a multifunctional medical shoulder joint rehabilitation trainer. Based on the first embodiment, the bottom of the cylindrical rod 33 is fixedly connected to a threaded rod 36, the outer wall of the threaded rod 36 is meshed with the inner wall of the threaded slider 32, the top of the threaded slider 32 is fixedly connected to a vortex spring 2 38, and the bottom of the slide rail 31 is fixedly connected to the correction component 4.

[0022] The training mechanism 3 also includes a metal wire straightening plate 39 fixedly connected to the top of the slide rail 31, the end of the vortex spring 2 38 away from the threaded slider 32 is fixedly connected to the bottom of the winding wheel 34, the inner wall of the through hole of the metal wire straightening plate 39 is slidably connected to the outer wall of the metal wire 35, and the end of the vortex spring 1 23 away from the take-up wheel 22 is fixedly connected to the top of the fixed plate 21.

[0023] The correction component 4 includes a telescopic rod 41 fixedly connected to the bottom of the slide rail 31, and the end of the telescopic rod 41 away from the slide rail 31 is fixedly connected to the slide rail 42, and the bottom of the slide rail 42 is fixedly connected to a hydraulic box 43. The bottom of the hydraulic box 43 is connected with several hydraulic telescopic tubes 44, and the bottom of the hydraulic telescopic tube 44 is fixedly connected to a rubber block 45. When the threaded rod 36 rotates along the inner wall of the threaded slider 32, when the threaded rod 36 moves downward to the bottom, the threaded rod 36 will no longer contact the inner wall of the threaded slider 32. At this time, the cylindrical rod 33 is inside the threaded slider 32, and the threaded rod 36 will no longer move downward. In addition, the hydraulic telescopic tube 44 is elastic, so that the device can adapt to patients of all sizes, avoiding excessive differences in patient size, causing the correction component 4 to exert excessive pressure on the patient's shoulders, resulting in excessive shoulder pressure and damage to the shoulders.

[0024] The correction component 4 also includes a sliding tube 46 that is slidably connected to the inner wall of the sliding rail 42. The end of the threaded rod 36 away from the cylindrical rod 33 is rotatably connected to the inner wall of the sliding tube 46. The side wall of the fixed rod 12 is fixedly connected with the push-back component 5. When the above-mentioned metal wire 35 extends outward, it will drive the take-up wheel 22 and the winding wheel 34 to rotate. The rotation of the winding wheel 34 will drive the bottom cylindrical rod 33 and the threaded rod 36 to rotate synchronously. The rotation of the threaded rod 36 will rotate along the inside of the threaded slider 32. During the rotation of the threaded rod 36, it will be affected by the internal thread of the threaded slider 32 and will gradually move downward, showing a Figure 6 As shown, the threaded rod 36 drives the sliding rail 42 and the hydraulic box 43 downward through the sliding tube 46, and the hydraulic box 43 drives the multiple hydraulic telescopic tubes 44 and the rubber block 1 45 downward, and forces the rubber block 1 45 to contact the patient's shoulders. The contact between the multiple hydraulic telescopic tubes 44 and the shoulders will apply a downward pressure on the patient's shoulders. Through the application of the above components, when the patient stretches outward, the rubber block 1 45 and the hydraulic telescopic tube 44 will compress the patient's shoulders and keep the patient's shoulders in a state of sinking. When the patient pulls downward, he or she will avoid applying force outward, causing the patient to shrug his or her shoulders and transfer the exercise force to other positions, affecting the training effect of the equipment.

[0025] The push back assembly 5 includes an air pressure chute 51 opened at the side wall of the fixed rod 12, and a piston plate 52 is slidably connected to the inner wall of the air pressure chute 51. A push plate 53 is fixedly connected to the side wall of the piston plate 52. A rubber block 2 54 is fixedly connected to the end of the push plate 53 away from the piston plate 52. By utilizing the downward movement of the hydraulic telescopic tube 44, a rubber block 2 54 and a transmission tube 55 are provided inside the equipment. When the hydraulic telescopic tube 44 is compressed and contracted, the internal space of the hydraulic telescopic tube 44 is reduced, and the hydraulic telescopic tube 4 The internal solution will pass through the hydraulic box 43 to the inside of the transmission pipe 55, and then be transmitted to the inside of the air pressure chute 51 through the transmission pipe 55. As the solution in the air pressure chute 51 increases, the piston plate 52 will slide outward along the inner wall of the air pressure chute 51, pushing the push plate 53, the rubber block 2 54 and the patient's back, forcing the patient's back to straighten forward, ensuring the stable force of the rotator cuff muscles of the back, and preventing the patient's arms from exerting force forward, causing the back to bend downward, resulting in the patient's posture being unstandard during training and affecting training efficiency.

[0026] The push-back assembly 5 also includes a transmission tube 55 that is connected to the side wall of the fixed rod 12. The end of the transmission tube 55 away from the fixed rod 12 is connected to the side wall of the hydraulic box 43. In order to solve the problem that the patient's arm will rotate significantly during training, a sliding rail 42 and a sliding tube 46 are provided inside the device. When the patient's arm is raised to the back, the winding wheel 34 will drive the cylindrical rod 33 and the threaded slider 32 to move synchronously along the inner wall of the slide rail 31 to avoid the pull wire being too long and the angle between the metal wire 35 and the top pull wire part being too large, resulting in excessive resistance to the metal wire 35 during stretching, thereby increasing the patient's training intensity. Through the application of the above-mentioned components, the influence of the angle on the pulling force is reduced, and a large change in the pulling force occurs.

[0027] The method for using the rehabilitation training device includes the following steps: S1: When in use, the patient installs the strap 11 around the waist, ensures that the mounting plate 1 is on the back, and ensures that the tightening mechanism 2 and the training mechanism 3 are on the shoulders of the patient; S2: The patient bends his elbow and inserts his fingers into the pull ring 37. He then pulls his arm outward to straighten it. After straightening his arm, he raises his arm back to his back. At this time, the wire 35 is pulled outward, causing the take-up wheel 22 and the winding wheel 34 to rotate. The rotation of the take-up wheel 22 applies a squeezing force to the vortex spring 1 23 at the bottom. S3: The spiral spring 23 accumulates mechanical power, and the reaction force generated by the mechanical power will continue to increase with the extension length of the metal wire 35, thereby increasing the pressure on the back muscles of the rotator cuff when the patient expands his chest.

[0028] A specific application of this embodiment is: when in use, the patient installs the strap 11 on the waist, and ensures that the mounting plate 1 is on the back, and ensures that the tightening mechanism 2 and the training mechanism 3 are on the shoulders of the person. At this time, the patient bends the elbow, inserts the fingers into the pull ring 37, and straightens the arm by pulling outward. After the arm is straightened, the patient raises the arm toward the back. At this time, due to the outward pulling of the metal wire 35, the take-up wheel 22 and the winding wheel 34 will rotate. When the take-up wheel 22 rotates, it will apply a squeezing force to the vortex spring 1 23 at the bottom. The vortex spring 1 23 accumulates mechanical power, and the reaction force generated by the mechanical power will continue to increase with the outward length of the metal wire 35, thereby increasing the pressure on the back muscles of the rotator cuff muscle group when the patient expands the chest, thereby improving the training effect of this position. Through the application of the above components, the patient's actions such as lying down and supporting before training are reduced, which cause excessive shoulder pressure and affect the effect of rehabilitation training.

[0029] When the metal wire 35 is extended outward, the take-up wheel 22 and the winding wheel 34 are driven to rotate. The rotation of the winding wheel 34 drives the bottom cylindrical rod 33 and the threaded rod 36 to rotate synchronously. The threaded rod 36 rotates along the inner thread of the threaded slider 32. During the rotation of the threaded rod 36, it is affected by the internal thread of the threaded slider 32 and gradually moves downward, showing a Figure 6 As shown, the threaded rod 36 drives the sliding rail 42 and the hydraulic box 43 downward through the sliding tube 46, and the hydraulic box 43 drives the multiple hydraulic telescopic tubes 44 and the rubber block 1 45 downward, and forces the rubber block 1 45 to contact the patient's shoulders. The multiple hydraulic telescopic tubes 44 contacting the shoulders will apply a downward pressure on the patient's shoulders. Through the application of the above components, when the patient stretches outward, the rubber block 1 45 and the hydraulic telescopic tube 44 will compress the patient's shoulders and keep the patient's shoulders in a state of sinking. When the patient pulls downward, it is avoided that the patient applies force outward, causing the patient to shrug and transfer the exercise force to other positions, affecting the training effect of the equipment. By utilizing the downward movement of the above hydraulic telescopic tube 44, The equipment is provided with a second rubber block 54 and a transmission tube 55. When the hydraulic telescopic tube 44 is compressed and contracted, the internal space of the hydraulic telescopic tube 44 is reduced, and the internal solution of the hydraulic telescopic tube 44 will pass through the hydraulic box 43 to the inside of the transmission tube 55, and then be transmitted to the inside of the air pressure chute 51 through the transmission tube 55. As the internal solution of the air pressure chute 51 increases, the piston plate 52 will slide outward along the inner wall of the air pressure chute 51, and push the push plate 53, the second rubber block 54 and the patient's back, forcing the patient's back to straighten forward, ensuring the stable force of the rotator cuff muscles of the back, and avoiding the patient's arms exerting force forward, causing the back to bend downward, causing the patient to have an irregular posture during training, and affecting the training efficiency.

[0030] In order to solve the problem that the patient's arm will rotate significantly during training, a sliding rail 42 and a sliding tube 46 are provided inside the device. When the patient's arm is raised to the back, the winding wheel 34 will drive the cylindrical rod 33 and the threaded slider 32 to move synchronously along the inner wall of the sliding rail 31 to avoid the wire being too long and the angle between the metal wire 35 and the top wire part being too large, resulting in excessive resistance to the metal wire 35 during stretching, thereby increasing the patient's training strength. Through the application of the above components, the influence of the pulling force on the angle is reduced, and a large change in the pulling force occurs. In addition, when the threaded rod 36 is threadedly rotated along the inner wall of the threaded slider 32, when the threaded rod 36 moves downward to the bottom, the threaded rod 36 will no longer contact the inner wall of the threaded slider 32. At this time, the cylindrical rod 33 is inside the threaded slider 32. At this time, the threaded rod 36 will no longer move downward. In addition, the hydraulic telescopic tube 44 is telescopic, so that the device can accommodate patients of various body types, avoiding excessive differences in patient body types, resulting in excessive pressure on the patient's shoulders by the correction component 4, resulting in excessive pressure on the shoulders and damage to the shoulders.
