[0049] During the thermal curing process, due to the dual limiting effect of the pressure strip 52 and the branching groove 31, the optical fiber will remain stable, ensuring the quality of the thermal curing.

[0050] After the heat curing is completed, the top plate 55 and the vertical plate 51 are pulled upward by the handle 551, so that the pressure strip 52 can be controlled to move out of the wire groove 41 and the vertical plate 51 can be limited by the cooperation of the eccentric wheel 6 and the limiting groove 61.
