[0015] The utility model has the following beneficial effects:

[0016] 1. By setting a longitudinal adjustment mechanism, when the longitudinal position of the optical fiber preform needs to be adjusted, the rotating shaft is turned, and the rotating shaft drives the bevel gear 1 to rotate, and the rotation of the bevel gear 1 drives the bevel gear 2 to rotate, and the rotation of the bevel gear 2 drives the threaded rod 1 to rotate. Under the action of the sliding rod, the lifting plate will move up and down.

High-precision docking is essential to ensure the performance and stability of the optical fiber communication system.

When the circular frame rotates, the connecting rods 1 on several fixed rods will change their angles under the action of the rotation of several rotating blocks, so as to get closer to or farther away from each other. The optical fiber preforms to be docked are fixed by adjusting several fixed wheels to ensure that the position and angle of the preforms will not change during the docking process, thereby greatly improving the docking accuracy. This is crucial to ensuring the quality and performance of the optical fiber connection, and can also reduce the number of manual adjustments required during the docking process, thereby speeding up the docking speed and improving production efficiency.
