[0002] In the fiber optic communication industry, the end face of the optical fiber usually needs to be ground and polished. This method is relatively cumbersome and costly. Subsequently, laser cutting of optical fibers has emerged in the industry to meet optical requirements while improving efficiency and reducing costs. However, laser cutting of optical fibers is sensitive to focal length. If the position of the optical fiber is inconsistent each time, or there is a pitch angle, it is easy to cause problems such as unstable angle of the optical fiber end face and poor length consistency after cutting. Therefore, the optical fiber needs to be installed on a fixture before cutting, and then the fixture needs to be placed on the laser cutting machine. Therefore, the operability and stability of the cutting fixture are very important.

[0024] Two X-direction sliding rods 13 are symmetrically arranged in the X-direction sliding groove 14, and the two ends of the X-direction sliding rod 13 are respectively connected to the two inner walls of the X-direction sliding groove 14, and an X-direction sliding hole is provided on the X-direction slider 4 at the position corresponding to the two X-direction sliding rods 13, and the X-direction slider 4 is slidingly connected to the two X-direction sliding rods 13 through the X-direction sliding hole; an X-direction spring 3 is provided on the surface of the X-direction sliding rod 13, and the X-direction spring 3 is located between the end of the X-direction slider 4 away from the assembly port 6 and the inner wall of the X-direction sliding groove 14.

[0025] Two Y-direction sliding holes are symmetrically provided on the cutting jig body 1 and on both sides of the assembly opening 6. The Y-direction limit assembly includes a Y-direction sliding rod 9 and a Y-direction limit block 11. The Y-direction sliding rod 9 is slidably connected to the Y-direction sliding hole. The two ends of the Y-direction sliding rod 9 are respectively connected to the top inner wall and the bottom inner wall of the Y-direction limit block 11. A Y-direction spring 7 is provided on the surface of the Y-direction sliding rod 9.

[0028] A specific embodiment of the present invention is:

[0029] First, push the X-direction slider 4 in the X-direction sliding groove 14 in the direction away from the assembly opening 6. Since the X-direction slider 4 is connected to the two X-direction limit blocks 5, the X-direction slider 4 drives the two X-direction limit blocks 5 to move in the same direction while pushing. Since the X-direction slider 4 is connected to the two L-shaped linkage sliders 10, the X-direction slider 4 drives the two L-shaped linkage sliders 10 to move in the same direction while pushing. The two X-direction limit blocks 5 lose the X-direction obstruction to the assembly opening 6 while moving. The two L-shaped linkage sliders 10 move the two connected connecting protrusions 8 in the same direction while moving. The two connecting protrusions 8 squeeze the Y-direction limit block 11 and push it upward. The two Y-direction limit blocks 11 lose the Y-direction obstruction to the assembly opening 6 while being squeezed and pushed. When the carrier 2 can be placed, stop pushing the X-direction slider 4 and assemble the carrier 2 into the assembly opening 6 through the PIN slot 16. , release the X-direction slider 4, and the X-direction slider 4 moves toward the assembly opening 6 under the reset action of the two X-direction springs 3. The X-direction slider 4 drives the two X-direction limit blocks 5 and the two L-shaped linkage sliders 10 to move in the same direction until the two X-direction limit blocks 5 support the carrier 2. The X-direction slider 4 and the two L-shaped linkage sliders 10 stop moving. At this time, the two X-direction limit blocks 5 limit the carrier 2 in the X direction, and the two L-shaped linkage sliders 10 drive the two connected connecting protrusions 8 to move in the same direction during movement. Therefore, the connecting protrusions 8 lose their squeezing effect on the Y-direction limit blocks 11. The two Y-direction limit blocks 11 move downward under the reset action of the connected Y-direction springs 7 until the two Y-direction limit blocks 11 support the carrier 2 and stop. The carrier 2 is limited and fixed in the X and Y directions with good stability. The cutting jig body 1 is placed on the laser cutting equipment to perform laser cutting operations.
