Angle gauges used clinically in domestic medicine are used to measure shoulder width, pelvis width, etc. There is a lack of portable measuring sticks for measuring the angle of joint movement, and some are also used in medical equipment such as "Isokinetic Testing Instrument - SYBIX", which uses the rotation of the limbs with fixed large joints, and the input data to the computer through the rotation of the power head to display the joint movement. Angle; and in the field of sports biomechanics, the use of image analysis software to identify joint motion angles is expensive and the actual operation is not simple enough. At the same time, the existing joint angle measuring device cannot display the measured value, which is inconvenient to use in the actual operation process, and there is a certain human error depending on the operator's reading.
