Abstract: A wire cutter head for preventing misalignment of cutting blades comprises two cutting members, the two cutting members respectively have a cutting face and a handle neck at two ends and are pivoted together at a middle position. The cutting face is a stepped inclined surface having a stopping surface formed with an inclined angle at an approximant middle section, such that the two stopping surfaces are flat with respect to each other, and a blade is formed at a lower edge of the cutting face. The handle neck is a plate used for controlling the pivot angle of the cutting blades. When the handle necks of the cutting members are pressed to rotate the cutting faces, the two facing stopping surfaces and the blades of the two cutting members contact each other. Therefore, the linear contact between the blades is free from misalignment and no offset gap between the blades occurs during operation.
