The invention discloses a folding type automatic constant temperature fuel gas soldering iron. A piezoelectric button sleeved on a gas valve button is arranged on one side at the upper end of an upper cover of the soldering iron, is connected with piezoelectric ceramics through a connecting rod, and is connected with a gas outlet valve through a valve opening lever; the gas outlet valve is connected with one end of a gas outlet pipe in a combustion cavity through a communication pipe; a base is arranged on the lower part of an outer pipe inner cavity of the combustion cavity; the gas outlet pipe is inserted into the center of the base; a horn mouth is formed at the other end of the gas outlet pipe; a thermal expansion pipe and a soldering bit are fixedly connected with each other sequentially on the upper part of the outer pipe inner cavity of the combustion cavity through a fastening screw; an injection pipe is inserted into the lower part in the thermal expansion pipe; a fixing sheet is arranged in a groove of the injection pipe, and is fixedly connected with an adjusting needle; the lower end of the adjusting needle is provided with an acuate body which is matched with the hornmouth of the gas outlet pipe; and a boss is arranged at one end, which is protruded out of an outer pipe, of the base, and is connected with the upper cover through a rotating shaft. The soldering iron is convenient to carry, is energy-saving, has long service life and meets the requirements of users to the greatest extent.
Description
technical field [0001] The invention relates to a gas soldering iron, in particular to a folding automatic constant temperature gas soldering iron. Background technique [0002] As we all know, gas soldering iron can bring great convenience to users because there is no power supply in remote mountainous areas without electricity, and is also very popular. But present gas soldering iron is that combustion-supporting cotton-like object is housed in the tip of the soldering iron. For the convenience of ignition, the exhaust hole is opened very large, and the heat loss is very large during combustion, the efficiency is low, and the temperature cannot be controlled. Therefore, there is an urgent need to develop a gas soldering iron with less heat loss, high efficiency and sufficient combustion to meet the needs of users. Contents of the invention [0003] According to the above-mentioned technical problems, the present invention provides a foldable automatic constant temperatu...
