摘要： A nailing machine includes a body, a nose extending from the body and having a nail guide channel therein, a driver reciprocally movable within the nail guide channel for driving the nail, and at least one first surface and at least one second surface formed on the end portion of the nose. The first surface extends perpendicular to the longitudinal axis of the nail guide channel. The second surface is formed in continuity with the first surface and is inclined at a predetermined angle with respect to the first surface.

摘要： A pneumatic percussion tool includes a head valve device including first and second head valves disposed in the body and movable in response to the pressure variation in the head valve chamber. The first and second head valves are positioned at a first position for preventing communication between the main air chamber and the percussion piston chamber while permitting communication between the percussion piston chamber and the outside of the body and preventing communication between the head valve chamber and the outside of the body when the compressed air is introduced into the head valve chamber through the change-over valve. The first and second head valves are movable from the first position to a second position for permitting communication between the main air chamber and the percussion piston chamber while preventing communication between the percussion piston chamber and the outside of the body and between the head valve chamber and the outside of the body when the compressed air has been discharged to the outside through the change-over valve. The first and second head valves are movable relative to each other for permitting communication between the head valve chamber and the outside of the body and for preventing communication between the percussion piston chamber and the outside of the body during the movement from the first position to the second position.
