[0041] The working principle of this utility model:

[0042] When in use, place the fixed shell 2 at a suitable position on one side of the joint angle measuring instrument body 1 so that the mounting block 3 corresponds to the position of the mounting slot 4, and then push the fixed shell 2 so that the mounting block 3 contacts the inner wall of the mounting slot 4 and moves along the inner wall of the mounting slot 4. When the fixed shell 2 moves to the appropriate position, pull the connecting clamp 607 to drive the binding belt 602 to be pulled out from the inner cavity of the accommodating slot 5. During the extraction process, the binding belt 602 will drive the winding column 601 to rotate, and the winding column 601 drives the control gear 603 to rotate synchronously. The control gear 603 drives the control rack 606 to rise on the surface of the support column 604 and squeeze the reset spring 605. When the binding belt 602 is pulled out to the appropriate length, wrap the binding belt 602 around the user's measuring joint, and then connect the connecting clamp 607 to the fixed shell. 2, and press the connecting clamp 607. The connecting clamp 607 pushes the fixed clamp 801 to move, and the fixed clamp 801 drives the control column 802 and the control board 804 to move synchronously and squeeze the control spring 803. When the connecting clamp 607 enters the inner cavity of the connecting groove 7, the force released by the control spring 803 after squeezing pushes the fixed clamp 801 to move in the opposite direction. The fixed clamp 801 drives the control column 802 and the control board 804 to move in the opposite direction synchronously and reset, thereby fixing the connecting clamp 607. At the same time, the force released by the reset spring 605 after squeezing pushes the control rack 606 to move in the opposite direction. The control rack 606 drives the control gear 603 and the winding column 601 to rotate in the opposite direction synchronously. The winding column 601 drives the binding belt 602 to tighten, so that the binding belt 602 tightens the measuring joint and completes the work.

[0043] To sum up: this human joint measuring instrument, by setting up the binding device 6 and the control device 8 for use in conjunction, solves the problem that most existing human joint angle measuring instruments do not have the function of fixing the joint angle measuring instrument to the measuring joint when in use. Usually, the measuring personnel are required to align the joint angle measuring instrument with the joint of the person being measured, and press the joint angle measuring instrument to fix the joint angle measuring instrument body to the measuring joint. The operation process is relatively cumbersome, and during use, the joint angle measuring instrument body may also fall off due to user operation errors.
