Adjustable gas cutting gun

The utility model discloses an adjustable gas cutting gun which comprises a handle, an oxygen pipe hand wheel, an oxygen pipe connector, an acetylene pipe connector, an acetylene hand wheel, a preheating oxygen hand wheel and a cutting nozzle, and further comprises a cutting oxygen pipe connected with a cutting oxygen hand wheel adjusting opening in a butt joint mode, and a mixed gas pipe connected with an acetylene hand wheel adjusting opening in a butt joint mode. The tail end of the cutting oxygen pipe and the tail end of the mixed gas pipe are matched with threaded holes in the two sides of the cutting nozzle respectively, and the spiral directions of external threads of the tail end of the cutting oxygen pipe and the tail end of the mixed gas pipe are opposite. By connecting the cutting nozzle with the cutting oxygen pipe and the mixed gas pipe through threaded connection structures with opposite rotating directions, in the specific use process, according to the requirements of the working environment, the angle, relative to the cutting oxygen pipe, of the cutting nozzle can be freely adjusted; after the angle is adjusted, the cutting oxygen pipe and the mixed gas pipe are locked together with the cutting nozzle through nuts, sealing is ensured, the cutting angle is changed on the premise that the relative positions of the cutting oxygen pipe and the handle are not changed, the adjustable gas cutting gun is suitable for gas cutting work under various complex environments, and the use range is enlarged.
