SCRIBER HOLDER

摘要

The present invention relates to a scriber holder comprising: a first contact surface which has one end part equipped with a holder head having a scribing wheel mounted thereon and is dented in a taper shape towards the holder head side in the other end part of a mounting unit inserted through an opening unit formed in a holder body; a second contact surface which shares the inner edge of the first contact surface in the other end part of the mounting unit and is dented in a taper shape towards the holder head; a third contact surface which is equipped in the opening unit and is coupled with the first and second contact surfaces so as to prevent the fluctuation of the scribing wheel to both sides of a moving direction so that the third contact surface is extended towards the entrance side of the opening unit and faces the first contact surface; a fourth contact surface which is extended towards the entrance side of the opening unit, is symmetrical to the third contact surface, and faces the second contact surface; and a permanent magnet of which the outer circumferential surface faces the inner surface of the opening unit and which is disposed at the rear of the third contact surface and fourth contact surface so as to settle and fix the mounting unit.
