WIPO Patent Application WO/2020/162341

A1

The present invention avoids the unintentional rotation of a wire insertion part with respect to an electrode holding part.　An electrode holding part 3 comprises: a holding part body 11 which is formed in a cylindrical shape into which an electrode 2 can be inserted, in which a screw 13a is formed, and which can rotate relatively with respect to a wire insertion part 4; insulators 12a, 12b; a cylinder part 13; a spring 14; an operating knob 21 which is formed in a cylindrical shape into which the cylindrical part 13 can be inserted, which can move in the cylinder length direction relative to the cylinder part 13, and which is attached to the cylinder part 13 in a state in which relative rotation is restricted; and a spring 22 which biases the knob 21 in the direction towards the cylinder part 13. An engagement part E4 is provided to an abutment part F4, which abuts the knob 21, of the insertion part 4, and an engagement part E3 is provided to an abutment part F3, which abuts the abutment part F4, of the knob 21. Relative rotation of the knob 21 with respect to the insertion part 4 is restricted by the engagement of the engagement parts E3, E4.
