Abstract

A handy torch comprises a tank, a first valve mechanism, a second valve mechanism, a burner having a nozzle and an air-intake opening. A pipe connects the second valve mechanism with the burner. The first valve mechanism includes a first valve body having a cylindrical inner wall with a female thread and a valve seat, an actuating member having a male thread screwed with the female thread of the first valve body, a disc, a resilient O-ring disposed between the valve seat and the disc. The O-ring is designed such that the gas flowing from an entrance of the first valve mechanism can be controlled by the O-ring in cooperation with the disc and the valve seat. A suction material connects the male thread of the actuating member with the gas in the tank. The second valve mechanism includes a second valve body having a passage and a through-hole with a female thread, and a needle having a male thread screwed with the female thread of the second valve body for controlling the gas flowing through the passage. A gas adjusting dial member is fixed to the needle. The torch comprises further a piezo-electric unit having an ignition button, an air adjuster and an air control lever. A casing houses therein at least partly the tank and others and has a gripped portion. The gas adjusting dial member, the air control lever and the ignition button are arranged near the gripped portion. The nozzle is inclined outwardly at an angle of 30-75 degree in respect to the longitudinal direction of the torch.
