先チツプの台金への固定構造。[Scope of Claim for Utility Model Registration] The cutting edge tip is fixed to the base metal by receiving the front, rear, and bottom surfaces of the base of the cutting edge tip in the receiving recess of the base metal, which consists of a front wall, a rear wall, and a bottom wall. In this structure, the base of the cutting edge tip has contact surfaces that contact the front and rear walls of the receiving recess on its front and rear surfaces, respectively, and the distance between the front and rear contact surfaces is directed toward the tip tip. one abutting surface is inclined relative to the other abutting surface so that the tip is smaller, and the front and rear walls of the receiving recess are inclined corresponding to the front and rear abutting surfaces of the chip, and the bottom of the receiving recess is An insertion space is formed between the wall and the bottom surface of the chip, and by inserting a pressing member into this insertion space, the front and rear contact surfaces of the chip are brought into pressure contact with the front and rear walls of the receiving recess. A structure that secures the cutting edge tip to the base metal.
