Abstract
The present invention relates to a gas exhaust system for a stapler for ejecting nails, comprising: a cylinder with a vertically movable piston, driven down by high-pressure gas; a valve body, set on the top side of the cylinder, controlling the inflow of the high-pressure gas into the cylinder; and an exhaust, having a cavity, which is open to the bottom side and accommodates the valve body, and several exhaust holes, which are connected to the cavity, the exhaust having a vertical protection plate at a distance from the exhaust holes, its area covering the exhaust holes, the exhaust further having a protruding protection ring made of soft material on the outer side close to the bottom side; wherein, when the piston moves upwards to the original position, exhaust gas is released through the cavity and the exhaust holes, with the protection plate preventing the exhaust gas from directly hitting any object, and wherein the protection ring minimizes mechanically hitting the outer side of the exhaust and the cylinder of an object, thus avoiding injuries or damages.
