Claims

[Claims for Utility Model Registration] 1. A first side and a second side are arranged at right angles, and the orthogonal inner surfaces of these first and second sides are used as a contact reference surface for a processing electrode, A seat groove is bored in the longitudinal direction of the outer surface of the first side, an elongated hole is provided along the center of the seat groove, and a serrated engagement part with a constant small pitch is formed on the bottom of the seat groove. A pedestal to be formed, and a pedestal that is slidably disposed on the inner surface of the first side of the pedestal, stands up at a right angle from the contact reference plane of the first side at the inner end, and is in contact with the inner surface of the second side. A fastening piece having contact surfaces for processing electrodes facing parallel to each other, and a fastening screw insertion hole communicating with the elongated hole on the first side being formed diagonally from the outer end toward the center, and a pedestal. an engagement piece having a serrated engagement surface with a constant small pitch that engages with the engagement portion on the first side of the engagement piece, and is movably disposed within the seat groove on the first side;
Loosely insert the tightening piece into the insertion hole of the tightening screw and the elongated hole on the first side of the pedestal, and lock the engaging piece with a screw at the tip, so that the tightening piece and the engaging piece are inserted into the first side of the pedestal. An electrode holder for an electrical discharge machine, characterized by comprising a tightening screw fixed to the side part. 2 A spherical seat is formed at the entrance end of the insertion hole of the tightening screw in the tightening piece, and a spherical washer on the lower surface is disposed in contact with the lower part of the head of the tightening screw, and the spherical seat is disposed in contact with the lower part of the head of the tightening screw. The screw is loosely inserted into an insertion hole formed in the engagement piece, and is inserted into a cylindrical locking piece that is rotatably accommodated in a housing hole formed in the engagement piece perpendicular to the insertion hole. An electrode holding device for an electric discharge machine according to claim 1, which is fixed with screws.
