The angle is measured by moving away from the main lever and using only the main measurement side of the main lever.

Make fine adjustments to match. In this state, the angle displayed on the angle display section is set to 0 degrees.
When the main lever 2 rotates in the direction of the arrow x in FIG. 1, the angle is positive, and when the main lever 2 rotates in the direction of the arrow y in FIG. 1, the angle is negative.

度を計測することができる。 When measuring the bending angle of the second joint of the finger, normally the secondary lever 3 is made to follow the main lever 2, and both levers 2 and 3 are measured in an integrated state, as shown in FIG. At this time, the angle of the main measurement side 7 and the sub measurement side 11 with respect to the reference side 6 is
Displayed as 0. In this way, by making the sub lever 3 follow the main lever 2, the main measurement side 7 is extended by the sub measurement side 11, so
It is possible to measure the refraction angle of not only the second joint of the finger but also large joints such as the wrist, elbow, knee, heel, etc., which require a relatively long measurement side.

の屈折角度を計測することができる。 Furthermore, when measuring the bending angle of the first joint of the finger, the angle is measured by bending the finger, as shown in FIG. At this time, the measurement area becomes narrow due to the thumb mound of the hand, and a relatively short measurement side is required. Therefore, the auxiliary lever 3 is separated from the main lever 2 and measurement is performed using the main measurement side 11 of the main lever 2. Thereby, as shown in FIG. 5, the angle of the main measurement side 7 with respect to the reference side 6 is displayed on the angle display section 10. In this way, by separating the secondary lever 3 from the main lever 2, it is possible to measure only with the relatively short main measurement side 7, so it is not limited to the first joint of the finger, but requires a relatively short measurement side. It is possible to measure the angle of refraction at small joints.

とができる。(Effects of the invention) As is clear from the above, the present invention includes a main lever having a main measurement side that forms a measurement angle with respect to the reference side, and a sub-measurement side that extends the main measurement side. By providing an auxiliary lever that follows the main lever in a removable manner, when measuring large joints, the measurement side can be relatively large and accurate measurements can be made by simply having the auxiliary lever follow the main lever. I can do it. In addition, when measuring the angle of a small joint or a part that narrows when the joint is bent, simply separating the secondary lever from the main lever makes the measurement side relatively small and allows accurate measurements to be made in accordance with the measurement location. can be measured.
