Two opposite sub-walls are provided in the gas reservoir to form a capillary groove to enable a liquid gas to flow upwards by means of capillary effect. The gas control valve has a section of outer threads in a lower part, a seal ring mounted around a neck portion, and disc portion on an upper part. The disc portion has a ratchet gear to carry out the flame adjustment. The gas control valve has a cylindrical hole for receiving a gas nozzle to control the flow of gas. A leaf spring made of plastic material to be molded integrally with the pressing plate and extends into a cylindrical reservoir beside that flint base so as to bias the pressing plate to push the gas nozzle downwards in order to close the gas nozzle.
