Since the intensity of the flame can be adjusted, it is possible to use the butane gas torch in combination with the isobutane gas fuel tank (see FIG. 15c).

그러므로 본 발명의 부탄가스토치는 가압밸브(21) 중심구멍(21a)에 연료개방관체(22)를 끼우거나, 분리하는 방법으로 부탄가스연료통과 이소부탄가스연료통에 같이 사용할 수 있는 효과를 낼 수 있고, Therefore, the butane gas torch of the present invention can produce an effect that can be used in both a butane gas fuel tank and an isobutane gas fuel tank by inserting or separating the fuel opening pipe body 22 in the central hole 21a of the pressurization valve 21 and ,
