The pointer 5 is fixedly connected to the outside of the first rotating shaft 3 and rotates together with the first rotating shaft 3, and points to the corresponding scale on the dial 6, so that the movement angle of the joint can be accurately displayed, and the measurement work is simple and efficient.

[0028] The force applying assembly is used to apply force to the joint to ensure the smooth bending of the joint. The force applying assembly comprises a second rotating shaft 10 rotatably connected to one side of the fourth clamping plate 8, a connecting plate 9 fixedly connected to the outer side of the third clamping plate 7 and arranged close to the second rotating shaft 10, a connecting rod 11 rotatably connected to the outer side of the connecting plate 9, and a driving assembly for driving the connecting rod 11 to move away from one end of the connecting plate 9. The third clamping plate 7 is fixedly connected to the outer side of the second rotating shaft 10. The driving assembly comprises two fixed plates 13 fixedly connected to the outer side of the fourth clamping plate 8, a screw rod 12 rotatably connected between the fixed plates 13, a movable block 15 threadedly connected to the outer side of the screw rod 12, and a knob 14 arranged on one side of one of the fixed plates 13.

When the movable block 15 moves, the third clamping plate 7 can be rotated with the second rotating shaft 10 as the center through the connection of the connecting rod 11 and the connecting plate 9. When the third clamping plate 7 exerts force on the joint, the passive bending of the joint can be realized, so that the subsequent activity angle measurement work can be carried out;

[0034] The first clamping plate 1 can be freely rotated through the rotation of the third clamping plate 7, so that the first rotating shaft 3 is rotated. The pointer 5 is fixedly connected to the outer side of the first rotating shaft 3, rotates together with the first rotating shaft 3, and points to the corresponding scale on the scale disc 6, so that the activity angle of the joint can be accurately displayed, and the measurement work is simple and efficient;
