Claims (1)

[Claims for Utility Model Registration] (1) Having a hole in the center through which the rod electrode 14 passes, and having grooves 122 to 125 at the tip that allow the hole to be tightened and moved in the axial direction; A chuck member 12 having a tapered surface 126 on its distal end surface; a hole through which the chuck member 12 is inserted; a hole through which the rod electrode 14 passes on the distal end side; and a conical shape continuous with this hole to receive the tapered surface of the chuck member. Chuck receiving members 9 to 11 having an inner wall surface and having a thread cut at the rear end; are screwed into the screws at the rear ends of the chuck receiving members 9 to 11, and by movement in the screwing direction due to this screwing. A screw member 13 that pushes the chuck receiving members 9 to 11 toward the tapered surface of the chuck member 12; approximately cup-shaped and pushing the chuck receiving members 9 to 11;
a head-side coupling member 5 through which the chuck receiving members 9 to 11 are coupled, and whose cup-shaped edge is threaded; a handle member 15; and a head-side coupling member fixed to the tip of the handle member 15; A handle side coupling member 16 having a screw threadedly engaged with the screw of No. 5; (2) It has a hole in the center through which the rod electrode 14 passes, has grooves 122 to 125 at the tip that allow tightening movement in the axial direction of the hole, and has a tapered surface 126 on the tip surface. Chuck member 12; has a hole through which the chuck member 12 is inserted, a hole through which the rod electrode 14 passes through on the distal end side, a conical inner wall surface continuous with this hole and receiving the tapered surface of the chuck member; The chuck receiving members 9 to 11 are threaded; the chuck member 12 has a hole through which the chuck receiving member 12 passes, and is screwed into the screw at the rear end of the chuck receiving member 9 to 11; A screw member 13 that pushes the chuck receiving members 9 to 11 toward the tapered surface of the chuck member 12 by movement of the chuck receiving members 9 to 11;
a head-side coupling member 5 through which the chuck receiving members 9 to 11 are coupled, and whose cup-shaped edge is threaded; a handle member 15; fixed to the tip of the handle member 15, through which the screw member 13 passes head side coupling member 5.
a handle-side coupling member 16 having a screw threadedly engaged with the screw of the handle member 15; and a head-side coupling member 5 coupled to the handle member 15;
A pushing member 18 that pushes the rear end of the chuck member 12 in the direction toward the tip by moving in the screwing direction by screwing the handle-side coupling member 16 together.
