[0054] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0055] See Figure 1 , Figure 1 This diagram illustrates the structure of a rehabilitation brace according to an embodiment of the present invention. The rehabilitation brace includes a locking assembly 10, a first fixing part 20, and a padding 30. The first fixing part 20 is used to fix the brace to the lower leg 60 (e.g.,...). Figure 11 As shown, the bracket 11 is mounted on the first fixing part 20, and the end of the locking member 12 is connected to the pad 30.

[0056] Please see Figures 3 to 6 , Figure 3 It shows Figure 1The diagram shows the structure of the locking assembly 10 of the rehabilitation brace. Figure 4 It shows Figure 3 Enlarged structural diagram at point B Figure 5 It shows Figure 3 The diagram shows a cross-sectional view of the locking assembly 10. Figure 6 It shows Figure 5 Enlarged structural diagram at point C. Specifically, the locking assembly 10 includes a bracket 11, a locking member 12, an unlocking member 13, and a driving member 14. The bracket 11 is mounted on the first fixing part 20 of the rehabilitation brace. The locking member 12 is elongated and movably mounted on the bracket 11. The locking member 12 has multiple locking portions 121 arranged along its length. One end of the locking member 12 is a free end, and the other end is connected to the pad 30. The unlocking member 13 is mounted on the bracket 11 and can lock and release the locking portions 121. The driving member 14 is rotatably mounted on the bracket 11 and has a first force-applying part 1411 and a second force-applying part 1431. The first force-applying part 1411 can abut against the locking portions 121 to drive the locking member 12 to move relative to the bracket 11 along its length. The second force-applying part 1431 is used for external force operation.

[0057] Specifically, the distance between the first force-applying part 1411 and the rotation axis of the driving member 14 on the bracket 11 is a first distance, and the distance between the second force-applying part 1431 and the rotation axis of the driving member 14 on the bracket 11 is a second distance, with the first distance being smaller than the second distance. Since the second distance is greater than the first distance, based on the lever principle, when the second force-applying part 1431 is pushed by hand, the forward pushing force of the first force-applying part 1411 on the locking member 12 is greater than the hand pushing force acting on the second force-applying part 1431. This ensures that the pad 30 is securely fixed to the lower leg 60, preventing it from easily coming loose and avoiding displacement during activities. The loosening and adjustment operation is also relatively convenient and quick.

[0058] As an optional solution, the size between the first distance and the second distance is not limited; for example, the second distance can be smaller than the first distance. When the second distance is smaller than the first distance, in order to save effort when rotating the drive component 14, an auxiliary component that can be detachably connected to the second force-applying part 1431 can be configured. By connecting the auxiliary component to the second force-applying part 1431, the force can be transmitted to the second force-applying part 1431. Also based on the lever principle, when the second force-applying part 1431 is pushed by the auxiliary component, the forward pushing force of the first force-applying part 1411 on the locking component 12 is greater than the force acting on the auxiliary component. This ensures that the pad 30 is securely fixed to the lower leg 60, preventing it from easily coming loose and avoiding displacement during activities. The loosening and adjustment operation is also more convenient and quick.

[0059] It should be noted that the length direction of the locking member 12 refers to the direction from one end of the locking member 12 to the other end of the locking member 12, such as... Figure 3 As shown by arrow S in the diagram.

[0060] When the aforementioned locking assembly 10 adjusts the tightness of the pad 30 against the back of the calf 60, the unlocking member 13 releases the locking part 121. Simultaneously, external force is applied to the second force application part 1431, causing the driving member 14 to rotate. When the driving member 14 rotates, it abuts against the locking part 121 of the locking member 12 through the first force application part 1411, causing the locking member 12 to move relative to the bracket 11 along its length. During the movement of the locking member 12, the pad 30 moves, causing the pad 30 to adhere tightly to the back of the calf 60. Once the position of the pad 30 is adjusted to the correct position, the unlocking member 13 locks the locking part 121. When it is necessary to loosen the pad 30 from the back of the calf 60, the unlocking member 13 releases the locking part 121, and the locking member 12 is removed. As can be seen, when the second force-applying part 1431 is pushed by an external force, the first force-applying part 1411 drives the locking part 12 to move forward, thereby ensuring that the pad 30 is securely fixed to the lower leg 60, preventing it from easily coming loose and avoiding displacement during activity. Adjustment is also relatively convenient and quick. Furthermore, the pad 30 fits snugly against the back of the lower leg 60 of patients with ligament injuries, ensuring proper support for the back of the lower leg 60 and guaranteeing a better rehabilitation effect.

[0061] Please see Figures 3 to 6 In one embodiment, the locking part 121 is a limiting groove provided on one side of the locking member 12. The unlocking member 13 can move into the limiting groove to lock the locking member 12, and can move outward from the limiting groove to release the locking member 12. Thus, when it is necessary to lock the locking member 12, the unlocking member 13 is moved into the limiting groove, and the unlocking member 13 abuts against the inner wall of the limiting groove to lock the locking member 12; when it is necessary to release the locking member 12, the unlocking member 13 is moved outward from the limiting groove, and the unlocking member 13 releases the locking member 12. At this time, the locking member 12 can be pushed to move freely along the length direction relative to the bracket 11 to adjust the tightness of the pad 30 on the lower leg 60.

[0062] Please see Figure 1 , Figure 4 and Figure 6, in one embodiment, the limiting groove is a one-way groove. Specifically, the limiting groove is provided with a first inner wall 1211 and a second inner wall 1212 arranged in sequence along the length direction of the locking member 12. Both the first inner wall 1211 and the second inner wall 1212 are arranged at an angle with the other side surface of the locking member 12. The angle between the first inner wall 1211 and the other side surface of the locking member 12 is a, and the angle between the second inner wall 1212 and the other side surface of the locking member 12 is b, where a < b. In this way, the limiting groove is a one-way groove, that is, the locking member 12 can move unidirectionally on the bracket 11, and the opposite moving direction will be restricted by the unlocking member 13 and cannot move. Additionally, when it is necessary to make the cushion 30 close to the calf 60, there is no need to manually adjust the unlocking member 13 to loosen the locking member 12. Since the limiting groove is a one-way groove, the driving member 14 can be directly acted on. When the driving member 14 receives a driving force, it drives the locking member 12 to move along its length direction, and the position of the locking member 12 can be correspondingly adjusted to make the cushion 30 close to the calf 60.

[0063] In one embodiment, a is 20° to 70°, specifically, for example, 20°, 30°, 35°, 45°, 50°, 60° and 70°, etc. In addition, b is 60° to 100°, specifically, for example, 60°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, etc.

[0064] As an alternative solution, the limiting groove is not limited to being set as the above-mentioned one-way groove, and it can be set as a groove with a two-way limiting function, that is, whether it is necessary to make the locking member 12带动 the cushion 30 close to the calf 60 or to make the locking member 12带动 the cushion 30 loosen from the calf 60, it is necessary to first move the unlocking member 13 out of the limiting groove, that is, to loosen the locking member 12 first and then adjust the position of the locking member 12.

[0065] As an alternative solution, the locking portion 121 is not limited to being the limiting groove in the above embodiment, and it can also be, for example, a convex block that is in limiting cooperation with the unlocking member 13.

[0066] Please refer to Figure 1 、 Figure 4 and Figure 6, in one embodiment, the unlocking member 13 is rotatably provided on the bracket 11. The unlocking member 13 is provided with a locking portion 131. When the unlocking member 13 rotates, the locking portion 131 can move into the limiting groove to lock the locking member 12, and can move outwards from the limiting groove to release the locking member 12. Thus, since the limiting groove is a one-way groove, the unlocking member 13 can rotate to make the locking portion 131 move into the limiting groove. After the locking portion 131 moves into the limiting groove, the locking portion 131 abuts against the second inner wall 1212 of the limiting groove to lock and fix the locking member 12, so that the locking member 12 can only move unidirectionally on the bracket 11; in addition, the unlocking member 13 can also rotate to make the locking portion 131 move out of the limiting groove, and after the locking portion 131 moves out of the limiting groove, the unlocking member 13 releases the locking member 12.

[0067] Please refer to Figure 1 、 Figure 4 and Figure 6 , specifically, the unlocking member 13 is provided with a first shaft hole 132, and the bracket 11 is provided with a second shaft hole 111. The unlocking member 13 is rotatably provided on the bracket 11 through a first rotating shaft (not shown in the figure) passing through the first shaft hole 132 and the second shaft hole 111.

[0068] Please refer to Figure 1 、 Figure 4 and Figure 6 , in one embodiment, the locking portion 131 is provided with two abutting surfaces 1311 arranged at an angle, the included angle between the two abutting surfaces 1311 is r, and the two abutting surfaces 1311 are respectively used to abut against the first inner wall 1211 and the second inner wall 1212 of the limiting groove. The first inner wall 1211 and the second inner wall 1212 are arranged at an angle, and the included angle between the first inner wall 1211 and the second inner wall 1212 is t, and r < t. Thus, since r < t, that is, the locking portion 131 can smoothly rotate and move into the limiting groove during the rotation of the unlocking member 13, and after the locking portion 131 rotates and moves into the inside of the limiting groove along with the unlocking member 13, the locking portion 131 has a good one-way fixing effect on the locking member 12.

[0069] Of course, as an optional solution, the two abutting surfaces 1311 of the locking portion 131 do not need to be arranged at an angle as in the above embodiment, and can also be, for example, arranged parallel to each other, and can also play a one-way fixing role on the locking member 12 after rotating and moving into the inside of the limiting groove.

[0070] Please refer to Figure 1 、 Figure 4 and Figure 6In one embodiment, the locking assembly 10 further includes a first reset member 15. The unlocking member 13 is connected to the bracket 11 via the first reset member 15. The first reset member 15 drives the unlocking member 13 to rotate, so that the locking part 131 moves into the limiting groove. Thus, under the reset force of the first reset member 15, the locking part 131 of the unlocking member 13 is always kept in the limiting groove, thereby always providing a unidirectional limiting and fixing effect on the locking member 12; only under the action of an external driving force can the unlocking member 13 overcome the reset force of the first reset member 15 and move the locking part 131 out of the limiting groove to unlock.

[0071] In one embodiment, the first reset element 15 is a torsion spring or an elastic block.

[0072] Please see Figure 1 , Figure 4 and Figure 6 In one embodiment, the driving member 14 includes a first driving plate 141, a rotating part 142, and a second driving plate 143. The first driving plate 141 and the second driving plate 143 are respectively connected to the rotating part 142. The rotating part 142 is rotatably mounted on the bracket 11, a first force-applying part 1411 is mounted on the first driving plate 141, and a second force-applying part 1431 is mounted on the second driving plate 143.

[0073] Please see Figure 1 , Figure 4 and Figure 6 Specifically, the rotating part 142 is provided with a third shaft hole 1421, and the bracket 11 is provided with a fourth shaft hole 112. The rotating part 142 is rotatably mounted on the bracket 11 through the third shaft hole 1421 and the fourth shaft hole 112 via a second rotating shaft (not shown in the figure).

[0074] Please see Figure 1 , Figure 4 and Figure 6 In one embodiment, the second drive plate 143 is provided with a clearance opening 1432 that exposes the unlocking member 13. In this way, the unlocking member 13 is exposed outside the bracket 11 through the clearance opening 1432, and can be directly acted upon, so that the locking part 131 of the unlocking member 13 moves out of the limiting groove, and the movement of the unlocking member 13 and the drive member 14 will not interfere with each other.

[0075] Please see Figure 1 , Figure 4 and Figure 6In one embodiment, the locking assembly 10 further includes a second reset member 16. The driving member 14 is connected to the bracket 11 via the second reset member 16, which is used to drive the driving member 14 to rotate and reset. Thus, during the process of adjusting the position of the locking member 12 by pushing the driving member 14 to rotate, the reset force of the second reset member 16 enables the driving member 14 to quickly reset, thereby allowing for rapid adjustment of the position of the locking member 12.

[0076] Furthermore, when the second reset member 16 drives the drive member 14 to rotate and reset, the first force-applying part 1411 of the drive member 14 abuts against the locking part 121. In this reset state, its function is the same as that of the unlocking member 13, that is, it locks and fixes the locking member 12, preventing the locking member 12 and the pad 30 connected to it from loosening from the back of the lower leg 60.

[0077] In one embodiment, the second reset element 16 is a torsion spring or an elastic block.

[0078] Please see Figure 1 In one embodiment, there are two locking components 10, which are respectively disposed on both sides of the first fixing part 20. The locking member 12 of one locking component 10 is connected to one side of the pad 30, and the locking member 12 of the other locking component 10 is connected to the other side of the pad 30. In this way, the locking members 12 of the two locking components 10 are respectively connected to the opposite sides of the pad 30. By driving the locking member 12 to move, the pad 30 can be adjusted to be firmly attached to the back of the calf 60, providing support to the back of the calf 60.

[0079] Please see Figure 1 , Figure 4 and Figure 6 Specifically, the pad 30 has a mounting portion 31 on its side, and the end of the locking member 12 is detachably mounted on the mounting portion 31. Furthermore, the pad 30 may be provided with a fixing rod 32, which can be abutted against and fixed to the back of the ligament patient's lower leg 60. The relevant dimensional parameters of the fixing rod 32 are set according to the actual situation of the ligament patient and are not limited here.

[0080] Please see Figure 1 and Figure 11In one embodiment, the first fixing part 20 is, for example, frame-shaped, including two first frame edges 21 and a first connecting plate 22 connecting the two first frame edges 21. The two first frame edges 21 are respectively used to fit against the left and right sides of the lower leg 60. The first connecting plate 22 is an arc-shaped plate used to fit against the front of the lower leg 60. Two locking components 10 are respectively disposed on the two first frame edges 21. Thus, after the first fixing part 20 is sleeved on the lower leg 60, the two first frame edges 21 fit against the left and right sides of the lower leg 60 respectively, and the first connecting plate 22 fits against the front of the lower leg 60. In this way, when the pad 30 is tightly attached to the back of the lower leg 60, the first fixing part 20 can achieve a good fixing effect on the lower leg 60. In addition, after the locking component 12 releases the pad 30, the first fixing part 20 can be easily removed from the lower leg 60, and the disassembly and assembly efficiency is high.

[0081] Please see Figure 1 and Figure 11 In one embodiment, the first fixing part 20 further includes at least one first strap 23. The two ends of the first strap 23 are respectively connected to two first frame edges 21. Thus, when the first fixing part 20 is installed on the lower leg 60, the first strap 23 fits against the front of the lower leg 60, which helps to securely fix the first fixing part 20 to the lower leg 60, while also making disassembly and assembly convenient and quick.

[0082] It should be noted that, in order to ensure the supporting and fixing effect of the first fixing part 20 on the lower leg 60, both the first frame edge 21 and the first connecting plate 22 are rigid components. In addition, the first strap 23 is a soft strap or elastic strap.

[0083] It should also be noted that the "first frame edge 21" can be a "part of the first connecting plate 22", that is, the "first frame edge 21" and the "other parts of the first connecting plate 22" are integrally formed; or it can be a separate component that can be separated from the "other parts of the first connecting plate 22", that is, the "first frame edge 21" can be manufactured independently and then combined with the "other parts of the first connecting plate 22" to form a whole. Figure 1 As shown, in one embodiment, the "first frame edge 21" is integrally formed as part of the "first connecting plate 22".

[0084] As an alternative, the first fixing part 20 is not limited to the combination of the two first frame edges 21 and the first connecting plate 22 mentioned above. For example, it can also be an arc-shaped plate or other structural plate that is fitted onto the front and side of the lower leg 60, as long as it can be worn on the lower leg 60.

[0085] Please see Figure 1 , Figure 2 and Figure 11In one embodiment, the rehabilitation brace further includes a second fixation part 40 and a movable component 50. The second fixation part 40 is used to fix to the thigh 70, and the second fixation part 40 is connected to the first fixation part 20 through the movable component 50. Thus, the second fixation part 40 is fixed to the thigh 70, the first fixation part 20 is fixed to the lower leg 60, and the first fixation part 20 is movably connected to the second fixation part 40 through the movable component 50, which can be adapted to the rehabilitation treatment of ligament patients.

[0086] Please see Figures 7 to 9 , Figure 8 It shows Figure 1 The diagram shown is an exploded view of the movable component 50 of the rehabilitation brace. Figure 9 It shows Figure 8 Enlarged structural diagram at point D Figure 10 It shows Figure 1 The diagram shows the structure of the limiting member 57 of the rehabilitation brace. In one embodiment, the movable component 50 includes a first rotating plate 51, a second rotating plate 52, a first connecting member 53, a second connecting member 54, a third connecting member 55, and a fourth connecting member 56. The first connecting member 53 and the second connecting member 54 are rotatably connected to one side of the first fixing part 20 and the second fixing part 40 via the first rotating plate 51. The third connecting member 55 and the fourth connecting member 56 are rotatably connected to the other side of the first fixing part 20 and the second fixing part 40 via the second rotating plate 52. The line connecting the rotation center of the first fixing part 20 for mounting the first connecting member 53 and the rotation center of the second fixing part 40 for mounting the second connecting member 54 is o, and the line connecting the rotation center of the first fixing part 20 for mounting the third connecting member 55 and the rotation center of the second fixing part 40 for mounting the fourth connecting member 56 is p. The lines o and p intersect. Thus, when the active component 50 is in operation, it provides good support for the thigh 70 and lower leg 60 of patients with ligament injuries during normal walking, while also allowing for flexible use of the rehabilitation brace. More specifically, one end of the first rotating plate 51 is rotatably connected to one side of the frame of the first fixing part 20 (specifically, for example, the side of the first frame 21 facing away from the lower leg 60) via the first connector 53, and the other end of the first rotating plate 51 is rotatably connected to one side of the frame of the second fixing part 40 (specifically, for example, the side of the second frame 41 facing away from the thigh 70) via the second connector 54. One end of the second rotating plate 52 is rotatably connected to the other side of the frame of the first fixing part 20 (specifically, for example, the side of the first frame 21 that fits against the lower leg 60) via the third connector 55, and the other end of the second rotating plate 52 is rotatably connected to the other side of the frame of the second fixing part 40 (specifically, for example, the side of the second frame 41 that fits against the thigh 70) via the fourth connector 56.

[0087] Please see Figure 2 , Figures 9 to 11 In one embodiment, the movable component 50 further includes a limiting member 57. The limiting member 57 is disposed on the first rotating plate 51 or the second rotating plate 52, and is used to abut against the first connecting member 53, the second connecting member 54, the third connecting member 55, the fourth connecting member 56, the frame edge of the first fixing part 20 or the frame edge of the second fixing part 40 when the frame edge of the first fixing part 20 rotates relative to the frame edge of the second fixing part 40 to a preset angle. Thus, when the lower leg 60 moves relative to the first fixing part 20 on it and the second fixing part 40 on the thigh 70, when the first fixing part 20 and the second fixing part 40 move to their limit angle, the limiting member 57 abuts against the first connecting member 53, the second connecting member 54, the third connecting member 55, the fourth connecting member 56, the frame edge of the first fixing part 20 or the frame edge of the second fixing part 40 to limit the movement. This prevents the first fixing part 20 and the second fixing part 40 from continuing to rotate relative to each other when they are in the abutting state, which is equivalent to restricting the range of motion of the thigh 70 and the lower leg 60, which is beneficial to the rehabilitation effect.

[0088] It should be noted that the first rotating plate 51 can be arranged on the side of the first fixing part 20 and the second fixing part 40 away from the lower leg 60, or it can be arranged on the side of the first fixing part 20 and the second fixing part 40 close to the lower leg 60; this is not limited here. To make the technical solution of the present invention clearer, in this embodiment, as... Figure 1 , Figures 9 to 11 As shown, the following is a detailed description using the example of the first rotating plate 51 located on the side of the first fixing part 20 and the second fixing part 40 away from the lower leg 60, and the second rotating plate 52 located on the side of the first fixing part 20 and the second fixing part 40 close to the lower leg 60.

[0089] In addition, please see Figure 2 , Figures 9 to 11 In one embodiment, the limiting member 57 is adjustablely disposed on the first rotating plate 51. The limiting member 57 is used to abut against the fourth connecting member 56 when the frame edge of the first fixing part 20 rotates relative to the frame edge of the second fixing part 40 to a preset angle. Thus, by adjusting the position of the limiting member 57 on the first rotating plate 51, the limit angle of rotation of the first fixing part 20 relative to the second fixing part 40 can be adjusted accordingly. Since this limit angle is determined based on the position of the limiting member 57, the placement position of the limiting member 57 on the first rotating plate 51 can be determined based on the limit angle.

[0090] Please see Figure 2 , Figure 9 and Figure 10In one embodiment, there are two limiting members 57, located on either side of the fourth connecting member 56. Thus, when the first frame and the second frame rotate relative to each other, the fourth connecting member 56 can abut against and be fixed to the upper limiting member 57 to prevent further relative rotation between the first and second frames, or abut against and be fixed to the lower limiting member 57 to prevent further relative rotation between the first and second frames, thereby achieving an angle q between the first and second frames (e.g., ...). Figure 13 (As shown) is within a preset angle range, such as 90° to 180°, 120° to 150°, or 105° to 150°, etc., which is set according to the actual situation of the ligament patient.

[0091] Please see Figure 2 , Figure 9 and Figure 10 In one embodiment, the first rotating plate 51 is provided with an arc-shaped notch 511, which is arranged along the moving path of the fourth connector 56 and exposes the fourth connector 56. The limiting member 57 is provided with a stop 571, which passes through the notch 511 and can abut against the fourth connector 56.

[0092] It should be noted that the moving path refers to the section of the path that the fourth connecting member 56 moves on the first rotating plate 51 during the mutual rotation of the first fixed part 20 and the second fixed part 40.

[0093] Please see Figure 2 , Figure 9 and Figure 10 In one embodiment, a step 512 is provided on the opening wall of the notch 511, and the limiting member 57 is adjustablely disposed on the step 512. Thus, with the limiting member 57 disposed on the step 512, it can be located within the notch 511, and does not need to be directly disposed on the surface of the first rotating plate 51, thus improving product performance. As an optional solution, the limiting member 57 can also be directly connected to the surface of the first rotating plate 51, eliminating the need for the step 512 described in the above embodiment on the opening wall of the notch 511; this is not a limitation here.

[0094] Please see Figure 2 , Figure 9 and Figure 10In one embodiment, the first rotating plate 51 is provided with an arc-shaped mounting hole 513. The arc-shaped setting direction of the mounting hole 513 corresponds to the arc-shaped setting direction of the notch 511. The limiting member 57 is mounted on the first rotating plate 51 through the mounting hole 513 by a fastener 572, and the fastener 572 is adjustablely positioned in the mounting hole 513 along the arc-shaped setting direction of the mounting hole 513. Specifically, the fastener 572 is, for example, a bolt, screw, screw, or other part that can be detachably fastened in the mounting hole 513. When it is necessary to adjust the mounting position of the limiting member 57 on the first rotating plate 51, the fastener 572 is loosened, and the position of the fastener 572 in the mounting hole 513 can be infinitely adjusted along the arc-shaped setting direction of the mounting hole 513. After the position of the fastener 572 in the mounting hole 513 is adjusted to the correct position, the fastener 572 is fastened in the mounting hole 513. Furthermore, since the arcuate direction of the mounting hole 513 corresponds to the arcuate direction of the notch 511, during the adjustment of the fastener 572 along the mounting hole 513, the stop 571 of the limiting member 57 is always adjusted along the notch 511, thus ensuring that the stop 571 of the limiting member 57 is always within the notch 511. Additionally, the mounting hole 513 may be specifically located, for example, on the step 512.

[0095] Please see Figure 2 , Figure 9 and Figure 10 In one embodiment, multiple angle marks are provided on the surface of the first rotating plate 51, and all angle marks are arranged sequentially along the notch 511. Thus, the angular position of the limiting member 57 on the notch 511 can be observed and determined through the angle marks, thereby allowing the determination of the rotation angle range of the first fixing part 20 and the second fixing part 40. Furthermore, the mounting position of the limiting member 57 on the first rotating plate 51 can be adjusted according to the angle marks, thereby adjusting the rotation angle range of the first fixing part 20 and the second fixing part 40 accordingly. Specifically, the angle marks may be, for example, scale lines, numbers, letters, etc., provided on the surface of the first rotating plate 51.

[0096] Please see Figures 11 to 12 , Figure 11 and Figure 12 It is shown that when the fourth connector 56 abuts against the upper limiting member 57, the included angle q between the first fixing part 20 and the second fixing part 40 is 180°. Under the abutment and limiting action of the limiting member 57, the fourth connector 56 can only move along the notch 511 and in the area between the two limiting members 57. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 180°, and the first fixing part 20 and the second fixing part 40 can rotate to make the included angle q less than 180°.

[0097] Please see Figures 13 to 14 , Figure 13 and Figure 14 It is shown that when the fourth connector 56 abuts against the upper limiting member 57, the included angle q between the first fixing part 20 and the second fixing part 40 is 165°. Under the abutment and limiting action of the limiting member 57, the fourth connector 56 can only move along the notch 511 and in the area between the two limiting members 57. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 165°, and the first fixing part 20 and the second fixing part 40 can rotate to make the included angle q less than 165°.

[0098] Please see Figures 15 to 16 , Figure 15 and Figure 16 It is shown that when the fourth connector 56 abuts against the upper limiting member 57, the included angle q between the first fixing part 20 and the second fixing part 40 is 135°. Under the abutment and limiting action of the limiting member 57, the fourth connector 56 can only move along the notch 511 and in the area between the two limiting members 57. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 135°, and the first fixing part 20 and the second fixing part 40 can rotate to make the included angle q less than 135°.

[0099] Please see Figures 17 to 18 , Figure 17 and Figure 18 It is shown that when the fourth connector 56 abuts against the lower limiting member 57, the included angle q between the first fixing part 20 and the second fixing part 40 is 105°. Under the abutment and limiting action of the limiting member 57, the fourth connector 56 can only move along the notch 511 and in the area between the two limiting members 57. That is, the first fixing part 20 and the second fixing part 40 cannot rotate so that the included angle q between them is less than 105°. When the first fixing part 20 and the second fixing part 40 rotate, the included angle q between them is greater than 105°. Furthermore, when the fourth connecting member 56 abuts against the upper limiting member 57, the included angle q between the first fixing part 20 and the second fixing part 40 is 135°. Under the limiting action of the limiting member 57, the fourth connecting member 56 can only move along the notch 511 and within the area between the two limiting members 57. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 135°, and when the first fixing part 20 and the second fixing part 40 rotate, the included angle q is less than 135°. Therefore, Figure 17 and Figure 18 When the first fixing part 20 and the second fixing part 40 shown rotate relative to each other, the included angle q ranges from 105° to 135°.

[0100] Please see Figure 1 , Figure 7 and Figure 11In one embodiment, the second fixing part 40 is, for example, frame-shaped, including two second frame edges 41 and a second connecting plate 42 connecting the two second frame edges 41. The two second frame edges 41 are respectively used to fit against the left and right sides of the thigh 70; the second connecting plate 42 is an arc-shaped plate used to fit against the back of the thigh 70. Thus, after the second fixing part 40 is sleeved on the thigh 70, the two second frame edges 41 fit against the left and right sides of the thigh 70 respectively, and the second connecting plate 42 fits against the back of the thigh 70. This achieves a better fixing effect of the second fixing part 40 on the thigh 70; in addition, it also facilitates the removal of the second fixing part 40 from the thigh 70, resulting in high disassembly and assembly efficiency.

[0101] Please see Figure 1 , Figure 7 and Figure 11 In one embodiment, the second fixing part 40 further includes at least one second strap 43, with both ends of the second strap 43 connected to two second frame edges 41 respectively. Thus, when the second fixing part 40 is installed on the thigh 70, the second strap 43 fits against the front of the thigh 70, which helps to securely fix the second fixing part 40 to the thigh 70, while also making disassembly and assembly convenient and quick.

[0102] It should be noted that, in order to ensure the supporting and fixing effect of the second fixing part 40 on the lower leg 60, both the second frame edge 41 and the second connecting plate 42 are rigid components. In addition, the second strap 43 is a soft strap or elastic strap.

[0103] It should also be noted that the "second frame edge 41" can be a "part of the second connecting plate 42", that is, the "second frame edge 41" and the "other parts of the second connecting plate 42" are integrally formed; or it can be a separate component that can be separated from the "other parts of the second connecting plate 42", that is, the "second frame edge 41" can be manufactured independently and then combined with the "other parts of the second connecting plate 42" to form a whole. Figure 1 As shown, in one embodiment, the "second frame edge 41" is integrally formed as part of the "second connecting plate 42".

[0104] As an alternative, the second fixing part 40 is not limited to the combination of the two second frame edges 41 and the second connecting plate 42 mentioned above. For example, it can also be an arc-shaped plate or other structural plate that is fitted onto the front and side of the thigh 70, as long as it can be worn on the thigh 70.

[0105] Please see Figure 1 , Figure 7 and Figure 11In one embodiment, there are two movable components 50. The frame edge of one side of the first fixing part 20 is connected to the frame edge of one side of the second fixing part 40 through one of the movable components 50, and the frame edge of the other side of the first fixing part 20 is connected to the frame edge of the second fixing part 40 through the other movable component 50.
