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.

[ What is claimed is:] [1.] A gas exhaust system for a stapler for ejecting nails, comprising:a cylinder with a vertical axis and a top side, said cylinder having a vertically movable piston with an original position close to said top side of said cylinder, said piston moving down, driven by high-pressure gas, so as to drive the ejection of one of said nails, and moving up to said original position thereafter;a valve body, set on said top side of said cylinder, controlling the inflow of said high-pressure gas into said cylinder; andan exhaust with a bottom side and an outer side, said bottom side mounted on said top side of said cylinder, said exhaust having a cavity, which is open to said bottom side and accommodates said valve body, said exhaust having a horizontal perimeter with a plurality of exhaust holes, which are connected to said cavity, said exhaust having a vertical protection plate at a distance from said exhaust holes,said protection plate having an area that covers said exhaust holes, said exhaust further having a protruding protection ring made of soft material on said outer side close to said bottom side;wherein, when said piston moves upwards to said original position, exhaust gas is released through said cavity and said exhaust holes, with said protection plate preventing said exhaust gas from directly hitting any object, and wherein said protection ring minimizes mechanically hitting said outer side of said exhaust and said cylinder by an object, thus avoiding injuries or damages.
