Patent ID: 7571840

Claim:
A safety adapted to be incorporated in a nailing device that comprises a housing containing therein a striker plate that is movable to a ready-to-strike position from which the striker plate is selectively released to strike a nail out of the housing, the safety being mounted to the housing to selectively prevent the striker plate from being moved to the ready-to-strike position, and the safety comprising: a release plate movably mounted in the housing in front of the striker plate, the release plate having an upper end forming a first inclination face, a recoiling spring being arranged above and acting against the upper end of the release plate to bias the release plate downward from a retracted position where the release plate is completely accommodated in the housing to a projecting position where a lower end of the release plate projects beyond a bottom of the housing; and a rotatable retainer rotatably mounted to the housing and located above the release plate and the striker plate, the retainer comprising at least one stop that is selectively set at a predetermined position to prevent the movement of the striker plate toward the ready-to strike position and a second inclination face engageable with the first inclination face of the release plate so that the retainer is normally set at a location where the stop is located at the predetermined position to prevent the movement of the striker plate toward the ready-to-strike position.
