The present invention relates to a safety net without a risk of overfire due to a liquefaction phenomenon by allowing the liquefied gas to stably and effectively vaporize.The present invention relates to a torch bar body; A gas cylinder coupled to the inside of the toroidal body; A first connection pipe connected to the gas pipe and provided on an upper side of the toroidal body; A gasifier coupled to an end of the first connection pipe and filled with gas discharged from the gas passage; A second connection pipe penetrating through the lower end portion of the inner upper end portion of the vaporization portion; A nozzle unit provided on an upper portion of the toroidal main body and connected to an end of the second connection pipe; And a cover which surrounds the outer and lower ends of the vaporizing part and the nozzle part.The present invention has the effect of promoting the vaporization rate of the liquefied gas while passing through the vaporizing portion of the gas discharged from the gas container, and injecting only the vaporized gas into the nozzle portion, thereby achieving complete combustion and providing high quality flame.;
