[0028] Specifically, first, the screw rod 14 is connected to the positioning block 161 via the first connecting shaft 15 and the second connecting shaft 16. When the first connecting shaft 15 and the second connecting shaft 16 are rotatably connected, the rotation of the positioning block 161 can be effectively offset. By rotating the screw rod 14, the positioning block 161 can be converted into an up and down push on the optical fiber to be fused.

[0029] Embodiment 2:

[0030] The adjustment component 2 includes a slide groove 21 and a slide rod 22. The slide groove 21 is provided on one side of the top of the optical fiber melting machine body 11. The slide rod 22 is fixedly arranged inside the slide groove 21.

[0031] The surface of the slide rod 22 is slidably connected with a mounting sleeve 23, and the top end of the mounting sleeve 23 is fixedly connected to the bottom end of the first positioning seat 111;

The forward or reverse rotation of the screw rods 14 can achieve precise adjustment of their extended lengths. It is worth noting that the screw rods 14 are connected to the positioning blocks 161 via the first connecting shaft 15 and the second connecting shaft 16. When the first connecting shaft 15 and the second connecting shaft 16 are rotatably connected, the rotation of the positioning blocks 161 can be effectively offset.

To ensure that the rotation of the positioning blocks 161 does not affect the optical fibers, a positioning groove 171 is provided on the inner wall of each positioning tube 13. Under the coordinated action of the positioning rods 17 on both sides, the positioning blocks 161 can only move up and down in the direction of the positioning grooves 171, thereby more effectively fine-tuning the optical fiber position, making the entire positioning adjustment structure simple and practical, easy to operate, and improving the quality and efficiency of welding.
