[0043] Embodiment 2
[0044] Refer to Figures 1-12 and, on the basis of Embodiment 1, further obtain that the tightening and loosening mechanism 3 includes a second clamping plate 31. The second clamping plate 31 is arranged at the left end of the first clamping plate 1. Inside the right end of the second clamping plate 31, a rotating shaft 32 is fixedly connected. At the back of the rotating shaft 32, a second I-shaped ring 331 is fixedly connected. At the front of the rotating shaft 32, a first I-shaped ring 33 is fixedly connected. A T-shaped hollow bar 333 is rotatably connected to the surface of the first I-shaped ring 33. Inside the right end of the T-shaped hollow bar 333, a rectangular bar 334 is fixedly connected.

At one end of the second spring 341, a T-shaped slider 342 is fixedly connected. A straight rod 343 is fixedly connected to the left side of the T-shaped slider 342. The right side of the T-shaped slider 342 is fixedly connected to the left end of the pulling rope 332. At the left end of the straight rod 343, an adjusting seat 35 is fixedly connected. The surface of the adjusting seat 35 is slidably connected to the inside of the second clamping plate 31. At the left end of the second clamping plate 31, a positioning long seat 36 is fixedly connected. An adjusting plate 37 is slidably connected to the inside of the second clamping plate 31. At the front of the adjusting plate 37, a cross bar 38 is fixedly connected. At the top of the cross bar 38, a third spring 381 is fixedly connected.

[0045] Further, a cross groove is formed inside the left end of the second clamping plate 31. The surface of the cross bar 38 is slidably connected to the inside of the cross groove.

By changing the fitting area between the adjusting plate 37 and the inside of the adjusting seat 35, the friction force between the adjusting seat 35 and the adjusting plate 37 can be changed. In this way, according to the patient's recovery situation, the tightness intensity of joint activities can be flexibly adjusted, and personalized training intensity adjustment can be realized.
[0046] Embodiment 3
[0047] Refer to Figures 1-12 , and on the basis of Embodiment 1, a disassembly and assembly mechanism 4 is further obtained. The disassembly and assembly mechanism 4 includes a support plate 41. There are two support plates 41, and the two support plates 41 are respectively fixedly connected to the top of the first clamping plate 1 and the top of the second clamping plate 31. A T-shaped block 42 is slidably connected inside the support plate 41. A fourth spring 43 is fixedly connected to the front of the support plate 41. A connecting bar 44 is fixedly connected to the front of the fourth spring 43. A clamping bar 45 is fixedly connected to the back of the connecting bar 44. The top of the T-shaped block 42 is fixedly connected to the bottom of the lower clamping cylinder 211.
[0048] Further, a slot is formed inside the support plate 41. The surface of the T-shaped block 42 is inserted into the inside of the slot. A clamping hole is formed on the surface of the T-shaped block 42, and the surface of the clamping bar 45 is matched with the inside of the clamping hole. Move the T-shaped block 42 so that it can smoothly slide out from the support plate 41. After completing the above steps, a brand-new upper clamping cylinder 221 and a sliding seat 212 can be replaced according to actual needs, thus completing the replacement operation.
[0049] During the actual operation process, when using this device, when using this device to provide rehabilitation support assistance for patients after minimally invasive joint trauma surgery, the patient's limb needs to be clamped and fixed first. The specific operation is to gently place the patient's limb between the lower clamping cylinder 211 and the upper clamping cylinder 221 to ensure that the limb is in a proper position. Subsequently, accurately clamp the upper clamping cylinder 221 on the lower clamping cylinder 211. At this time, push the positioning vertical bar 226, and the positioning vertical bar 226 will drive the T-shaped long shaft 225 connected to it, and then the limiting block 224 will smoothly move inside the guide seat 222. As the positioning vertical bar 226 moves, it will closely fit between the lower clamping cylinder 211 and the upper clamping cylinder 221. Finally, use the bolt 227 to firmly fix the positioning vertical bar 226 to the lower clamping cylinder 211, and thus the installation operation is completed.
[0050] When it is necessary to adjust the clamping and fixing according to the thickness of the patient's limb, rotate the bidirectional lead screw 213. Since the bidirectional lead screw 213 is stably supported by the sliding seat 212, its rotation will drive the sliding block 214 to slide along a specific track. The sliding of the sliding block 214 will drive the articulated rod 215 hinged to it to move, and the movement of the articulated rod 215 will cause the short shaft 216 to move synchronously. The movement of the short shaft 216 further drives the I-shaped circular shaft 219 to move along the inclined slot track inside the inclined slot plate 218. The movement of the I-shaped circular shaft 219 will push the inclined slot plate 218 to lift in height, and finally realize the adjustment of the distance between the upper clamping cylinder 221 and the lower clamping cylinder 211. Through such an adjustment mechanism, accurate and comfortable clamping and fixing can be achieved according to the different limb thicknesses of patients.
[0051] When the patient's joint has recovered to a certain extent and corresponding joint activity training is required, the patient moves the arm joint, and this action will drive the pulling rope 332. During the movement of the pulling rope 332, it will drive the rotating shaft 32 to overcome the elastic force of the second spring 341, so that the rotating shaft 32 slides inside the groove seat 34. At the same time, this process will cause the adjusting seat 35 and the adjusting plate 37 to be closely attached and generate friction. This friction can provide corresponding resistance support for joint activities, effectively preventing the patient from causing secondary damage to the joint due to excessive amplitude during activities. In addition, the tightness intensity of joint activities can also be adjusted according to the patient's recovery situation. Specifically, rotate the T-shaped fork 384, and the rotation of the T-shaped fork 384 will drive the clamping rod 39 to rotate synchronously, so that the clamping rod 39 disengages from the inside of the positioning long seat 36. Then, move the cross bar 38, and the movement of the cross bar 38 will drive the adjusting plate 37 to move in position. By changing the fitting area between the adjusting plate 37 and the inside of the adjusting seat 35, the friction force between the adjusting seat 35 and the adjusting plate 37 can be changed. In this way, the tightness intensity of joint activities can be flexibly adjusted according to the patient's recovery situation, realizing personalized training intensity adjustment.
[0052] In addition, when it is necessary to replace the upper clamping cylinder 221 and the sliding seat 212 according to the patient's arm or limb condition, the operation is also very simple and fast. Just pull the connecting bar 44, and the pulling of the connecting bar 44 will drive the clamping bar 45 to disengage from the inside of the T-shaped block 42. Then, move the T-shaped block 42 so that it can slide out smoothly from the support plate 41. After completing the above steps, a brand-new upper clamping cylinder 221 and sliding seat 212 can be replaced according to actual needs, thus completing the replacement operation.
