Based on the above, it is clear that the present invention is primarily embodied as a carrying angle measuring tool 1000 to facilitate visual measurement of the carrying angle between the upper arm 40 and forearm 50 of a patient.
In one aspect, the invention is practiced by applying the first measurement ruler 10 to the patient's upper arm 40 with the patient's elbow joint fully straightened, so that the first measuring line 101 is parallel to the central axis of the patient's upper arm 40, and the disc protractor 30 is located at the elbow joint of the patient, and then the second measuring ruler 20 is slowly rotated, such that the second measurement ruler 20 is attached to the forearm 50 of the patient, such that the second measurement line 201 thereon is parallel to the central axis of the forearm 50 of the patient, in this way, referring to the angle scale 301 on the disc protractor 30 that is closest to the second measurement line 201, the size of the carrying angle between the upper arm 40 and the forearm 50 of the patient can be accurately measured, so that the size error of the measured carrying angle is smaller relative to the traditional visual measurement mode, and then the subsequent determination of the elbow deformity of the patient is difficult to have wrong judgment.

And the unit of the angle scale 301 is "degrees".
Thus, it will be appreciated that, in practice, between the zero degree tick mark 3011 and the ninety degree tick mark 3012, there are other angle value tick marks in "degrees".
In this embodiment, the first measuring line 101 is preset in the first measuring ruler 10; the protractor scale lines 301 are preset in the disc-shaped protractor 30; the second measuring line 201 is preset in the second measuring ruler 20.

In a specific embodiment, the other end of the first measuring ruler 10 and the other end of the second measuring ruler 20 both protrude outward to form an arc-shaped structure.
Therefore, when the present invention is used, the other end of the first measuring scale 10 and the other end of the second measuring scale 20 are not easy to hurt the arm of the patient.
In addition, in the present technical solution, the length of the first measuring ruler 10 and the length of the second measuring ruler 20 are both L; the L is 10.0cm-20.0 cm.
Preferably, in one embodiment, the L is set to 15.0cm, so that the L is neither long nor short, and is suitable for nearly all patients with different arm lengths.
In a specific implementation, both the width of the first measuring ruler 10 and the width of the second measuring ruler 20 are D; and D is 2.0cm-5.0 cm.
Preferably, in one embodiment, the D is set to 3.0cm, so that it is neither wide nor narrow, and thus fits moderately outside the arm 2000 of a patient with different arm sizes to suit patients with different arm sizes.
It should be added that, in implementation, in a preferred embodiment, the rotating member 302 includes a hollow rotating column 3021 and a fixed plug 3022 adapted to be inserted into the hollow rotating column 3021;
wherein, the outer diameter of the hollow rotating column 3021 is matched with the inner diameter of the rotating hole 202; the height of the hollow rotating column 3021 is matched with the thickness of the second measuring scale 20; the upper part of the fixing plug 3022 is provided with a fixing lug 30221 with an outer diameter slightly larger than that of the hollow rotating column 3021;
