されていたくたとえば実公昭５ｏ−５９８９参照ン 。[Prior Art] Conventionally, in this type of plasma torch device, a connecting pin formed on a connecting end surface of a conductor of a torch body is simply inserted into a connecting hole formed on a connecting end surface of a conductor of a torch head. The torch body and torch head can be attached and detached by screwing the connection thread part of the connection ring placed on the circumference of the connection part of the torch head to the connection thread part formed on the circumference of the connection part of the torch body. For example, see Utility Model Publication No. 5o-5989 for some proposed connections.

破損されてしまう欠点かあった。If the connection force between the torch head and torch body by the connection ring decreases below the appropriate value due to loosening of the connection ring or insufficient threading, the connection pin and connection hole may become loose due to vibrations during operation, etc. The disadvantage is that the torch head or torch body moves away from the torch head while resisting the contact force between them, and as a result, the contact area between the connecting pin and the connecting hole decreases, resulting in poor electrical contact. In addition, there was the disadvantage that the torch head or the unnecessary 7ti could fall off and be damaged when attached to or removed from the torch body.
