[0026] Please refer to Figures 1-4 , the present utility model provides an optical fiber cutting fixture, which includes a base 1. A plurality of parallel-arranged arc-shaped grooves 2 are opened on the top side wall of the base 1. Symmetrically distributed pressing plates 3 are arranged on the upper surface of the base 1. A plurality of parallel-arranged arc-shaped grooves 4 are opened on the lower surface of the pressing plate 3. The arc-shaped grooves 2 and the arc-shaped grooves 4 are correspondingly arranged, and the arc-shaped grooves 4 are located directly above the arc-shaped grooves 2 for tightly fixing the positions of multiple optical fibers. A cutting groove 18 is opened on the upper surface of the base 1, and the cutting groove 18 is located between the two pressing plates 3. Symmetrically distributed support seats 5 are fixed on one outer wall of the base 1, and one end of the pressing plate 3 is slidably connected to the side wall of the support seat 5. A support seat 6 is fixed between the side walls of the support seats 5 close to each other. The support seat 5 and the support seat 6 are vertically arranged. A support seat 7 is arranged below the support seat 6, and the support seat 7 and the support seat 5 are vertically arranged.

[0027] One end of the pressing plate 3 is fixed with a connecting plate 8. The connecting plate 8 and the pressing plate 3 are vertically arranged. A connecting plate 9 is fixed between the two connecting plates 8. The connecting plate 8 and the connecting plate 9 are vertically arranged. A threaded hole 10 is opened on the upper surface of the connecting plate 9 in the vertical direction. The upper surface of the support seat 7 is rotatably connected with an adjusting shaft 11. The top end of the adjusting shaft 11 passes through the threaded hole 10 and the support seat 6 and is fixed with a rotating plate 12. The rotating plate 12 and the adjusting shaft 11 are vertically arranged. An adjusting thread 13 is opened on the outer wall of the adjusting shaft 11. The adjusting shaft 11 is in threaded transmission connection with the connecting plate 9, and can quickly adjust the position of the pressing plate 3, so as to tightly cut the position of the optical fiber.

[0028] Above the second support base 6, a slider 14 slidably connected to the outer wall of the adjustment shaft 11 is installed. A fixed block 15 is fixed to the bottom side wall of the slider 14. The slider 14 and the fixed block 15 are perpendicularly arranged. Symmetrically distributed fixing grooves 16 are formed in the upper surface of the second support base 6 along the circumferential direction. The fixing grooves 16 and the fixed block 15 are in snap-fit, which can further fix the position of the adjustment shaft 11 after adjustment, ensuring the fixing stability of the optical fiber position. A return spring 17 is fixed to the top side wall of the slider 14. The other end of the return spring 17 is fixed to the side wall of the rotating plate 12. Among them, the elastic force of the return spring 17 can ensure the stable snap-fit between the fixed block 15 and the fixing groove 16.

[0029] The working process of this solution is as follows: When compacting the optical fiber, by holding the rotating plate 12 and hooking the slider 14 with a finger, the slider 14 drives the fixed block 15 to move, and the fixed block 15 is separated from the fixing groove 16. Then rotate the rotating plate 12, and the rotating plate 12 drives the adjustment shaft 11 to rotate. The adjustment shaft 11 drives the second connecting plate 9 to move through screw drive. The second connecting plate 9 drives the first connecting plate 8 to move. The first connecting plate 8 drives the pressing plate 3 to move, so that the pressing plate 3 moves away from the base 1. Then place the optical fiber into the first arc-shaped groove 2 respectively. Rotate the rotating plate 12 in the reverse direction. The rotating plate 12 drives the adjustment shaft 11 to rotate. The adjustment shaft 11 drives the second connecting plate 9 to move through screw drive. The second connecting plate 9 drives the first connecting plate 8 to move. The first connecting plate 8 drives the pressing plate 3 to move, so that the pressing plate 3 compresses and fixes the optical fiber, thereby fixing the position of the optical fiber. Then cut the optical fiber.
