[0026] Reference Figure 2As shown, in this embodiment, the slip ring fixing fixture 4 includes a sleeve 41 and a cap-shaped member 42 fixedly connected to the sleeve 41. The sleeve 41 is connected to the outer shell 7 through a connecting hole 9. The upper end of the sleeve 41 is fixedly connected to the rotor part of the optical fiber slip ring 5. The cap-shaped member 42 is fixedly arranged at the lower end of the sleeve 41. A connecting sleeve 43 is fixed on the cap-shaped member 42. The external part of the connecting sleeve 43 is detachably connected to the clamping joint 3, and the clamping joint 3 is fixedly connected to the rotating shaft 10. Through the provided connecting sleeve 43 and the clamping joint 3, after being fixedly connected to the rotor part of the optical fiber slip ring 5 to be tested through the sleeve 41, the connecting sleeve 43 is fixedly connected to the clamping joint 3, and then the clamping joint 3 and the optical fiber slip ring 5 to be tested are driven by the driving motor to rotate synchronously, so as to subsequently change the rotation speed of the optical fiber slip ring 5 to be tested and test the application performance of the optical fiber slip ring 5.

[0027] In this embodiment, a connecting flange 1 is fixedly provided on the lower end of the rotating shaft 10 , and is fixedly connected to the output shaft of the driving motor via the connecting flange 1 .
