Abstract
A restriction mechanism for a pneumatic nailer includes a secondary valve unit including a second axle with a seal ring mounted thereto and the second axle is movable along a hollow axial passage of the second frame. A second frame includes an annular portion, the hollow axial passage and guide holes. A seal ring is mounted to the annular portion and the second chamber communicates with the hollow axial passage via the guide holes. The seal ring on the second axle removably seals the hollow axial passage to control communication between the second frame and the second axle. The second valve unit has to be pulled before pulling the trigger to shoot the nail. The sequence cannot be reverse so as to form a safety operation mechanism.
