[0022] In the implementation of the scheme, the operator first places the positioning belt 11 in the hollow position in the middle of the patient's patella, so that the magnetic strip one 12 is adsorbed together and bound to the position of the patient's patella for positioning, and then the operator binds the measuring shell 41 to the position of the patient's thigh and calf, so that the magnetic strip two 42 magnetically attracts the measuring shell 41 together to measure the leg circumference of the patient's thigh and calf. Since it is magnetic attraction, the force of adsorption is not large, and it will not cause discomfort to the patient.

[0023] In the implementation of the scheme, the operator first places the positioning belt 11 in the hollow position in the middle of the patient's patella, so that the magnetic strip one 12 is adsorbed together and bound to the position of the patient's patella for positioning, and then the operator binds the measuring shell 41 to the position of the patient's thigh and calf, so that the magnetic strip two 42 magnetically attracts the measuring shell 41 together to measure the leg circumference of the patient's thigh and calf. Since it is magnetic attraction, the force of adsorption is not large, and it will not cause discomfort to the patient.

[0024] Specifically, in order to adjust the height, as shown in Figure 5 , in the scheme, the fixing assembly 2 comprises two fixing blocks 21, one end of each of the two fixing blocks 21 close to each other is fixedly connected with the left and right parts of the outer surface of the positioning belt 11, the front and rear parts of the one end of each of the two fixing blocks 21 far away from each other are fixedly connected with two fixing plates 22, one end of each of the two fixing plates 22 close to each other is fixedly connected with a spring 23, and one end of each of the springs 23 close to each other is fixedly connected with a clamping plate 24.

[0025] Further, referring to Figure 3 and Figure 5The adjusting assembly 3 comprises two fixed shells 31, the outer surfaces of the two fixed shells 31 are fixedly connected with the inner cavities of the fixed blocks 21 at the same part, the inner cavities of the two fixed shells 31 are slidably connected with adjusting plates 32 at the ends close to each other, the ends close to each other of the two adjusting plates 32 at the same part are fixedly connected with pull ropes 33.

[0026] Further, referring to Figure 5 The pull rope 33 comprises pull blocks 331, the ends close to each other of the two pull blocks 331 are fixedly connected with the ends far from the center of the four pull ropes 33 at the left part and the right part, and the ends far from each other of the two pull blocks 331 are fixedly connected with handles 332.

[0027] Further, referring to Figure 5 The ends close to the center of the four clamping plates 24 are slidably connected with the ends far from each other of the two fixed blocks 21.

[0028] When the leg circumference of other patients needs to be measured, the operator first pulls the handle 332 to drive the pull block 331 and the pull rope 33 to make the adjusting plate 32 slide back into the inner cavity of the fixed shell 31 or pulls the measuring shell 41 to make the adjusting plate 32 slide out of the inner cavity of the fixed shell 31, so as to adjust the position of the measuring shell 41, thereby realizing the length adjustment of the adjusting plate 32 and the distance adjustment of the measuring shell 41 according to different patients. At this time, the spring 23 is stretched to make the clamping plate 24 clamp the pull rope 33, thereby fixing the pull rope 33, so as to avoid the change of the length of the adjusting plate 32 and the distance of the measuring shell 41 caused by the movement or sliding of the patient. The clamping force of the clamping plate 24 does not affect the pulling of the handle 332 or the change of the length of the adjusting plate 32 by the measuring shell 41, and the clamping force of the clamping plate 24 only avoids the sliding of the pull rope 33 caused by the movement or shaking of the patient.
