ABSTRACT:
A wire twister designed for ordinary one-handed use which provides improved positive gripping action to the wire. A rotatable shaft having a wire clenching tip portion is rotatably mounted on a frame. The tip portion includes an open slot for receiving the wire ends, a scored seat region and a spring biased tapered scored plug. A rod attached to the rear of the plug extends lengthwise of the rotatable shaft to the rear of the frame, where it is connected to a thumb operated lever pivotably mounted on the frame for retracting the plug away from the seat region when installing the wire ends. The shaft is rotatable by a conventional transmission mechanism operated by a trigger located forward of a handle portion secured to the frame. The wire clenching tip is relatively small so that the object being secured by the wire is not obscured from view.
