The utility model discloses a further setting: two tool guiding grooves which are internally tangent to the stamp hole and aligned with the first blade and the second blade are arranged on the connecting body along the row direction, and one end of each tool guiding groove extends into the cutting notch.

By adopting the technical scheme, the cutter leading groove is arranged, the thickness and the strength of the connecting body part are further reduced, the first blade and the second blade can be fed into the cutter leading groove, and the deviation of the cutting track of the blade is avoided.

The utility model discloses a further setting: the cutting piece further comprises a sliding plate and a handle, the sliding plate is attached to the connecting body and is in sliding fit with the connecting body, the first blade and the second blade are fixedly arranged on the end face of the sliding plate and move along with the sliding plate, and the handle is fixedly connected with the sliding plate.

By adopting the technical scheme, the sliding plate is attached to the connecting body and is in sliding fit, the sliding plate is tightly attached to the connecting body, the phenomenon that the cutting piece moves when being cut to influence the quality of the cutting surface is avoided, and the handle is convenient for an operator to hold and apply force.

The utility model discloses a further setting: the first blade and the second blade are triangular, the inclined side faces of the first blade and the second blade are blade edge faces, and the blade edge faces are arranged from the direction of the stamp hole through the cutting notches.

By adopting the technical scheme, the blade edge surface of the blade is arranged to be inclined, so that the cutting action is formed in the cutting process, and the operation is easier.
