a second blade is arranged on one side, away from the first blade, of the cutter head;

one side of the cutter head, which is far away from the first cutting edge, is provided with a raised arc-shaped part, and the second cutting edge is arranged at the edge of the arc-shaped part.

Preferably, the bending angle of the hook part is 20-45 degrees.

Preferably, the handle comprises a handle plate and a clamping plate, one end of the handle plate is fixedly connected with the cutter head, the other end of the handle plate is inserted with the clamping plate in a staggered mode, and bolts penetrate through staggered positions of the handle plate and the clamping plate.

Compared with the related art, the nose flange cartilage cutting tool provided by the utility model has the following beneficial effects:

the utility model forms the hook part at the end part of the tool bit, and the knife is inserted in a manner of puncturing the nose flange cartilage through the first blade at the tip end of the hook part, because the area of the tip end position of the hook part is small, the knife insertion and knife stopping positions on the cartilage surface are more accurate, the success rate of single accurate cutting of the cartilage is high, the cutting efficiency can be improved, and the arrangement of the second blade at the edge of the arc part ensures that the application has the function of the traditional tool, and the cartilage edge and the surface are convenient to scrape and cut.
