The outer wall of the second small diameter pipe (42) below is threaded for The thread is screwed onto the body part of the gas hose (20) for attachment to it, with the needle rod assembly (30) installed perpendicular to the body section of the gas hose (20) by the tube. The large diameter or knob (31) the first small diameter tube (41) the second small diameter tube (42) respectively, and the needle axis (33) coexist with the needle axis (33) acting up and down to Close open the gas carrier (40). 2.A set of mechanism for adjusting the gas volume of the welding handle with a ton knob, vertical needle axis. The needle axis does not rotate. According to claim 1, where the needle axis (33) is tubular The cylinder at the bottom end has a conical appearance (35) for the closing function. And open the gas transport path (40) page 3 of the number 4 pages 3.A set of gas adjusting mechanism of welding handle with a knob to push the needle axis vertically. The needle axis does not rotate. According to claim 1, where inside the first small diameter tube (41) there is a pin (36) to steer the needle axis (33) to be perpendicular and not inclined when pressure is applied. 4.A set of gas adjustment mechanism of welding handle with a knob to push the needle axis vertically. The needle axis does not rotate. According to claim 1, within the second small diameter tube (42), there is a sleeve to support the needle axis (37) to force the needle axis (33) to be perpendicular and not. Inclination when pressure is applied 5.A set of gas adjusting mechanism of welding handle with a knob to push the needle axis vertically. The needle axis does not rotate. According to claim 1, inside the second small diameter tube (42), there is a gas-resistant rubber ring (38) below the needle axle (37) and is fitted to the needle shaft (33) as a gas shield. It flows from the gas hose (40) through the needle axis (33) up to the top. 6.A set of gas adjustment mechanism of welding handle with a knob to push the needle axis vertically. Attach the needle axis not turning according to claim 1, where at one position within the gas funnel (40) there is a needle shaft support ring (39) on the needle axis (33) that comes into contact with the needle axis support ring (39). This stops the gas flow and closes the gas channel (40). 7.A set of mechanism for adjusting the gas volume of the welding handle with a knob to push the needle axis vertically. The needle axis does not rotate. According to claim 1, where the central position of the body part of the gas pipe (20), there are two opposite positions of curvature (23).
