When the guard plate 1 is fitted against the patient's leg, clamp the clamping rod 9 and the clamping hole 7 again to fix the position of the guard plate 1. A limit plate is provided at one end of the extension plate 4 and is located inside the fixed frame 3. Two second springs 15 are provided on one side of the limit plate, and one end of the two second springs 15 are connected to the inner wall of the fixed frame 3; through the spring of the second spring 15, a thrust or a pull can be generated on the extension plate 4, which can drive the extension plate 4 to move. Two limit rods 16 are provided on one side of the fixed frame 3, and two limit holes 17 are provided on the surface of the push plate 5. The two limit rods 16 are both located inside the limit holes 17. The push plate 5 is connected to the fixed frame 3 through the limit rods 16. The push plate 5 moves along the limit rods 16, and the moving range of the push plate 5 can be limited.

[0022] As attached Figure 3 As shown, the fixing assembly includes connecting blocks 10 arranged at both ends of the elastic band 2, the surfaces of the two guard plates 1 are provided with sliding grooves, the surfaces of the guard plates 1 and on both sides of the sliding grooves are provided with multiple fixing holes 11, one side of the two connecting blocks 10 is located on one side of the guard plate 1, one side of the two connecting blocks 10 is provided with a pull ring, and the other side of the two connecting blocks 10 is provided with two fixing rods 12, the two fixing rods 12 are clamped with the fixing holes 11, the fixing rods 12 are separated from the fixing holes 11, and after the elastic band 2 is moved to a suitable position, the fixing rods 12 are clamped with the fixing holes 11.

[0023] As attached Figure 1 As shown, two support plates 13 are provided on one side of the two groups of guard plates 1. One end of the two support plates 13 is movably connected to the surface of the guard plates 1. Two adjacent support plates 13 are connected by bolts. By adjusting the angle between the two guard plates 1, the patient's legs can be bent.

[0024] As attached Figure 2As shown, U-shaped sponges 14 are provided on the inner side of the two sets of guard plates 1. The two U-shaped sponges 14 and the guard plates 1 can be detachably connected. Since the U-shaped sponges 14 are relatively soft, they can not only improve the comfort of the patient's legs, but also avoid collisions between the patient's legs and the guard plates 1.

[0025] Working principle of the utility model: when in use, first press the push plate 5 to move the push plate 5 along the limit rod 16, insert the push rod 6 into the clamping hole 7 on the surface of the fixed frame 3, push out the clamping rod 9 in the clamping hole 7, so that the first spring 8 is extended and retracted, and then the limit plate and the extension plate 4 are pushed by the elasticity of the second spring 15, so that the distance between the two guard plates 1 can be adjusted to the maximum range, release the push plate 5, and push the clamping rod 9 to clamp the clamping hole 7 on the surface of the fixed plate by the elasticity of the first spring 8, so that the extension plate 4 can be fixed;

[0026] Then, the two adjusted guard plates 1 are placed on both sides of the patient's legs, and the push plate 5 is pressed to release the fixation of the extension plate 4. The extension plate 4 and the guard plate 1 are driven to move by the pulling force of the second spring 15, so that the two guard plates 1 fit the patient's legs, so that the U-shaped sponge 14 between the two guard plates 1 is compressed, and the U-shaped sponge 14 can continue to protect the patient's push plate 5, which can not only reduce the pressure generated between the two guard plates 1, but also improve the comfort of the patient's legs. After the guard plates 1 fit the patient's legs, the push plate 5 is released, so that the clamping rod 9 can be clamped with the clamping hole 7;

[0027] Then pull the connection blocks 10 on both sides of the elastic band 2 to separate the fixing rod 12 on one side from the fixing hole 11 on the surface of the guard plate 1, so that the elastic band 2 moves along the slide groove on the surface of the guard plate 1, and the elastic band 2 contacts the patient's leg, and then snap the fixing rod 12 on one side of the connection block 10 into the fixing hole 11 on the surface of the guard plate 1, and then start to adjust the position of the elastic band 2;

[0028] By rotating the bolt between the two connecting blocks 10, the tightness between the two connecting blocks 10 can be adjusted according to the condition of the patient's legs, which can be convenient for the patient to use. The utility model can be suitable for patients of different body shapes by adjusting the distance between the two guard plates 1. By separating the fixing rod 12 from the fixing hole 11, the position of the elastic band 2 can be quickly fixed.
