Abstract
An adapter for a driver of a rotary tool, and including a pin and slot combination effective between an adapter body and an adapter collar which is slidable on the body. A pin and slot combination guides the sliding and a spring urges the collar with its pin and slot combination into a tool locking position. The slot in the combination is at an acute angle relative to the longitudinal axis of the adapter, and thus it secures the working tool relative to the body and does so by means of a rotary action for the collar which actually also induces the axial movement of the collar for the securing of the tool. The tool has a conical surface oriented opposite to that of a collar conical surface which bears upon the balls for the tool tightening action mentioned. The method of securing the tool is included in the aforementioned.
