ABSTRACT:
A compression spring is compressed between an internal surface of a cavity within a base and the wide end of a plunger the shaft of which passes through the compression spring and out of a conically countersunk opening of the cavity. A tapered end of a ferrule is pivotally mounted to the external end of the plunger. The ferrule is fixed in a position perpendicular to the axis of the plunger so that when the ferrule is allowed to pivot toward alignment with the axis of the plunger, the plunger is drawn into the cavity by the action of the compression spring until the tapered end of the ferrule mates with the conically countersunk external opening of the cavity restricting motion of the ferrule that is lateral to the axis of the ferrule.
