And a heat conducting plate 7 is arranged in the upper base 6 and the lower base 16;

[0019] When in use, after placing the optical fiber grating into the optical fiber groove 15 between the upper base 6 and the lower base 16, rotate the threaded rods 2 above the two sides of the body 1, so that the threaded rods 2 drive the moving plates 3 to move. At this time, after the two sides of the moving plates 3 slide above the clamping blocks 4, the clamping blocks 4 slide above the sliding rods 5, and the upper base 6 and the lower base 16 are connected, so that the upper base 6 and the lower base 16 on both sides approach each other to fix the optical fiber grating;

The refrigeration cavity 9 is symmetrically arranged about the centers of the upper base 6 and the lower base 16. And blowers 8 are arranged in the refrigeration cavities 9. And the blowers 8 are fixedly connected to the inside of the refrigeration cavities 9. And a water delivery pipe 10 is arranged in the refrigeration cavities 9.
