Abstract
A device for providing sufficient time to allow the piston to move backward completely of a nailer includes a movable member engaged with a front open end of the cylinder in the barrel of the nailer and a fixed member which is matched with the movable member. The movable member is pushed toward the fixed member by the piston when firing a nail and a passage is defined between the movable member and the fixed member so as to introduce air into the cylinder to push the piston backward. A space is defined between the movable member and the inner periphery of the cylinder when the movable member is moved toward the fixed member. A tiny hole is defined through the wall of the cylinder and release the air in the space slowly so that the passage is not sealed for a period of time such that the piston has sufficient time to move back.
