Elastic bands 15 are provided on one side of the second flexible piece 6 and the fourth flexible piece 9, and fixing rings 16 adapted to the elastic band 15 are provided on one side of the first flexible piece 5 and the third flexible piece 8. The front end of the elastic band 15 passes through the fixing ring 16, and is bent and fixed to the rear end of the elastic band 15 by Velcro 14. Support plates 17 are provided on the first flexible piece 5, the second flexible piece 6, the third flexible piece 8 and the fourth flexible piece 9, and the upper and lower adjacent support plates 17 are axially connected by a bridge piece 18.

[0024] When this embodiment is actually working, the first flexible sheet 5, the second flexible sheet 6, the third flexible sheet 8 and the fourth flexible sheet 9 are all fixed at the user's knee joint by winding with the elastic band 15 and the Velcro 14, and an adjustment device 7 is connected between the first flexible sheet 5 and the second flexible sheet 6. The distance between the third flexible sheet 8 and the fourth flexible sheet 9 can be adjusted by the first connecting sheet 10 and the Velcro 14, and then the tightness can be adjusted. The support plate 17 provides structural support for the knee joint, and the rivet buckle 13 slides in the first long hole 12 and the second long hole 27 to adjust the spacing. Velcro 14 is used for fixing. The overall structure is relatively soft, and the design of the adjustment structure is also more user-friendly, with soft adjustment, simple structure, and easy operation. It is more comfortable for users to wear and suitable for users to wear for a long time, effectively improving the user experience and product grade.

[0025] Further, the adjusting device 7 of the present embodiment includes an I-shaped piece 19, a movable piece 20 and two connecting rod pieces 21. The two sides of the upper end of the I-shaped piece 19 are respectively connected to the first flexible piece 5 and the second flexible piece 6. The lower end of the I-shaped piece 19 is provided with two extension pieces 22, and the ends of the extension pieces 22 are provided with a hook portion 23. The opposite ends of the third flexible piece 8 and the fourth flexible piece 9 are provided with a first limiting hole 24, a second limiting hole 25, and a third limiting hole 26. The front end of the extension piece 22 is bent and passed through the first limiting hole 24, the second limiting hole 25, and the third limiting hole 26. The first limiting hole 24, the second limiting hole 25, and the third limiting hole 26, the hook portion 23 can be hooked at the third limiting hole 26, a vertical second long hole 27 is opened in the middle of the I-shaped piece 19, the two ends of the two connecting rod pieces 21 are respectively axially connected to the lower ends of the third flexible piece 8 and the fourth flexible piece 9, the other ends of the two connecting rod pieces 21 and one end of the movable piece 20 are slidably axially connected to the second long hole 27 through the rivet buckle 13, and the movable piece 20 can be fixed on the I-shaped piece 19 through the Velcro 14. Therefore, when it is necessary to adjust the spacing between the first flexible sheet 5 and the second flexible sheet 6, the movable sheet 20 is pulled upward or downward, and the movable sheet 20 slides and moves on the second long hole 27 through the rivet buckle 13, and then the movable sheet 20 drives the overlapping ends of the two connecting rod sheets 21 to move upward or downward, and the other ends of the two connecting rod sheets 21 pull the lower ends of the first flexible sheet 5 and the second flexible sheet 6 to be relatively tightened, or vice versa to loosen. When adjusted to a suitable tightness, the movable sheet 20 is adhered to the I-shaped sheet 19 through the Velcro 14, and then the above-mentioned adjustment structure is simple, and fits the user's legs, and the user is easy to operate.

[0026] Furthermore, the support plate 17 of this embodiment is fixed to the first flexible sheet 5, the second flexible sheet 6, the third flexible sheet 8, and the fourth flexible sheet 9 by means of rivet buckles 13. Therefore, the support plate 17 is effectively fixed, and can further effectively support the user's knee joint, ensure the accuracy of the knee joint position, provide structural support, and promote the rehabilitation of the knee joint.

[0027] Furthermore, the lower end of the first flexible sheet 5 of this embodiment is connected with a reinforcing belt 28, and the reinforcing belt 28 is connected to the second flexible sheet 6 through the Velcro 14. The reinforcing belt 28 is located between the first flexible sheet 5 and the third flexible sheet 8, and can tighten the meniscus of the user's knee joint when fixed, thereby effectively promoting the rehabilitation treatment of the knee joint.

[0028] Furthermore, the first flexible sheet 5, the second flexible sheet 6, the third flexible sheet 8, and the fourth flexible sheet 9 of this embodiment are all provided with a receiving bag 29, and one end of the support plate 17 is placed in the receiving bag 29. Therefore, one end of the support plate 17 is inserted into the receiving bag 29. The other end is fixed by the rivet buckle 13, and then the support plate 17 can move within a certain range in actual use, thereby improving the overall flexibility during use and reminding the user of comfort during use.

[0029] Furthermore, the support plate 17 of this embodiment is made of titanium alloy. Titanium alloy is a multi-purpose metal material, which is light and high in strength. The density of titanium alloy is only half of that of steel, but its strength is close to that of ordinary steel, and even exceeds that of aluminum, which makes titanium alloy have excellent application prospects in the fields of aviation and aerospace; it has good corrosion resistance, and a dense oxide film will naturally form on the surface of titanium alloy. This film has high stability and tolerance, so it is difficult to rust; it has good biocompatibility, and titanium alloy has good compatibility with human tissue, so it is widely used in the medical field, such as artificial joints, dental implants, etc.; in addition, titanium alloy also has the characteristics of high wear resistance and high hardness, so it is widely used in aviation, aerospace, chemical industry, ocean, medical and other fields, so titanium alloy is the preferred material for the support plate 17, and can effectively improve the product grade.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
