The invention provides a wing-shaped optical fiber core adjustment structure. The structure comprises main body assemblies, a cam adjustment assembly, and a pressing hammer assembly, wherein a lens, acore adjustment V-shaped groove and a discharge electrode of each main body assembly participate in optical fiber core adjustment as a whole; and during operation, optical fiber imaging distances anddistances between optical fibers and the electrodes remain unchanged, and core adjustment pivots and force output points can be flexibly arranged. The wing-shaped optical fiber core adjustment structure provided by the invention has the advantages that the space occupation ratio of the core adjustment structure is reduced, so that a basic platform can be provided for the installation of other function control modules for special optical fiber splicing, fiber Bragg grating sensor manufacturing, optical fiber tapering, end cap splicing, vertical imaging of end surfaces of spliced optical fibers, polarization-maintaining optical fiber splicing, photonic crystal optical fiber splicing, non-electrode heating splicing, and the like; compared with the conventional design, the core adjustment structure achieves higher simplicity in structure, a higher core adjustment resolution, higher reliability, lower structure cost and lower processing requirements; and the core adjustment structure can be further applied for X/Y-axis core adjustment of the conventional optical fiber fusion splicer.
