Abstract
A nailing gun is formed with a cylinder. The cylinder has an inner wall. The inner wall has a plurality of exhausting holes. The cylinder has a piston. The piston is connected to a piston rod. The periphery of the piston has at least one annular groove. The annular groove has an O ring and a C ring therein. The C ring and O ring are arranged radially. The C ring is positioned at the outer side of the O ring and encloses the O ring. When the piston is installed in the cylinder, the C ring is resisted by the elastic force of the O ring. Because of the confinement of the inner wall of the cylinder, the tilt opening will close so that the C ring resists against the inner wall of the piston to be tightly adhered to the inner wall.
Claims4
A nailing gun having a cylinder;
- the cylinder having an inner wall;
- the inner wall having a plurality of exhausting holes which radially penetrate exhausting holes in the inner wall, the cylinder having a piston;
- a periphery of the piston having at least one annular groove;
- the annular groove having an O ring and a C ring therein;
- the C ring and O ring being arranged radially;
- the C ring being positioned at an outer side of the O ring and enclosing the O ring;
- the C ring being resisted by an elastic force of the O ring so that the C ring resists against the inner wall of the piston to be tightly adhered to the inner wall.
