[0045] The notches 223 are provided in three groups at equal intervals and arranged in a circumference on the disk 222 .

[0046] When using the present invention, the patient's legs are straightened, and then the first mounting plate 11, the fixing plate 211, and the second mounting plate 13 are placed on the side of the knee. The first mounting plate 11 and the first fixing belt 12 are fixed to the thigh by the first Velcro, and the second mounting plate 13 and the second fixing belt 14 are fixed to the calf by the second Velcro. The fixing plate 211 is then fixed to the side of the knee. Since the back of the patient's knee is not blocked, the doctor can directly observe the condition of the back of the patient's knee.

[0047] If the patient needs to move, the adjusting rod 225 is rotated to drive the rotating rod 221 to rotate, and the rotating rod 222 drives the disk 222 to rotate, and the disk 222 drives the notch 223 to rotate, so that the fixing column 216 slides from the high arc surface of the notch 223 to the low arc surface. As a result, the fixing column 216 drives the sliding block 214 to slide toward the middle of the fixing plate 211, so that the second tooth groove 215 is disengaged from the first tooth groove 213. When the adjusting rod 225 moves to the groove 35, the groove 35 locks the adjusting rod 225 through the protrusion 226. At this time, the calf can drive the rotating cylinder 212 to rotate freely, and the calf can move freely.

[0048] If the degree of knee bending needs to be adjusted, the calf drives the rotating drum 212 to adjust the fixing belt to an angle that the patient considers comfortable, and then the adjusting rod 225 is released. The adjusting rod 225 is reset under the action of the spiral spring 224, and the adjusting rod 225 drives the disc 222 to rotate, and the disc 222 drives the notch 223 to rotate, so that the fixing column 216 slides from the low arc surface of the notch 223 to the high arc surface, and the fixing column 216 then drives the sliding block 214 to slide from the middle of the fixing plate 211 to the outside, and the first tooth groove 213 and the second tooth groove 215 are re-engaged and locked, thereby achieving the function of stable fixation. The rotating drum 212 cannot rotate, and the patient's leg position is fixed.

[0051] The arc plate 34 is M-shaped to facilitate the movement of the protrusion 226 .

[0052] When the present invention is in use, the adjusting rod 225 is rotated, and the adjusting rod 225 drives the protrusion 226 to rotate at the same time. When the protrusion 226 rotates to the position of the arc plate 34, the protrusion 226 squeezes the arc plate 34, thereby sliding from the arc plate 34 into the groove 35. Under the action of the first spring 32 and the second spring 33, the groove 35 and the protrusion 226 are locked. If it needs to be unlocked, the arc plate 34 is pressed to squeeze the first spring 32 and the second spring 33, and the groove 35 leaves the protrusion 226. The protrusion 226 loses the locking effect of the groove 35 and is reset under the action of the spiral spring 224.
