It comprises a lower rack(210) positioned in the rear of a loading knob(220); an upper rack(380); a pinion gear(390) moving the racks in opposite direction to each other; a pressure shut-down valve(320) having a gas vessel and a hole(328); a gas discharge device(112) positioned under the valve(320). |
