A stapler extension mechanism is disclosed that is attached to the operating handle of a squeeze handle stapler that permits the stapler to be operated against a ceiling without the operator having to climb onto a ladder, against a floor without the operator having to bend over, or into a wall. The stapler extension mechanism has a head that is fastened to the operating handle of the squeeze handle stapler and an adjustable elongated handle is attached to the head.
