[0027] Refer to Figures 1 - 6, a detachable support plate 4 is installed on the horizontal part of the adjusting plate 3. The support plate 4 is of an L-shaped structure. Two transverse long circular holes 17 are formed on the upper surface of the horizontal part of the adjusting plate 3. Two through holes 16 matching with the transverse long circular holes 17 are formed on the upper surface of the horizontal part of the support plate 4. A limit screw 11 is inserted into the through hole 16. The lower end of the limit screw 11 penetrates through the long circular hole and is threadedly connected with a nut 12. A rotary encoder 5 is installed at the upper position on one side of the vertical part of the support plate 4. The rotary encoder 5 is connected with a connecting disk 7 through an elastic coupling 10. A through port is formed on one side of the vertical part of the support plate 4. The output end of the rotary encoder 5 penetrates through the through port and is connected with the elastic coupling 10. A convex shaft is fixedly connected to the middle position of the surface of the connecting disk 7 facing the elastic coupling 10. The convex shaft is inserted into the elastic coupling 10 and is fixedly connected with the elastic coupling 10. The elastic coupling 10 is used to connect the rotary encoder 5 and the connecting disk 7, and the turntable 13 is installed in the space formed by two chucks 8, so as to realize the elastic connection between the turntable 13 and the rotary encoder 5. The elastic connection mode has a good damping effect and can output signals stably. A vertical long circular hole 15 is formed on the vertical part of the adjusting plate 3, and a transverse long circular hole 17 is formed on the horizontal part of the adjusting plate 3, so as to adjust the position of the positioning screw 2 in the vertical long circular hole 15 and adjust the position of the limit screw 11 in the transverse long circular hole 17, so as to finely adjust the position of the rotary encoder 5.

[0028] Refer to Figures 1 - 8, on the side of the connecting plate 7 facing away from the elastic coupling 10, there are two semi-circular chucks 8. On the side of the connecting plate 7 facing the elastic coupling 10, a plurality of small holes 20 are arranged at equal intervals in a ring shape. Connecting screws 6 that are threadedly connected to the chucks 8 are inserted into the small holes 20.
