The invention relates to a double-acting lift-positioning energy-saving gas stove, and the technical scheme thereof is as follows: at least two outward-tilting bars are evenly arranged at the bottom of a hearth along the circumferential direction and are evenly distributed on the outer edge of a cavity cover; at least two inward-tilting bars are evenly arranged at the bottom of a lift fire tray along the circumferential direction and are evenly distributed on the inner edge of the cavity cover; the outward-tilting bars and the inward-tilting bars correspond to each other in a one-to-one manner and are in matched connection via a tilting plate respectively, the middle part of the tilting part is arranged on the cavity cover in a hinged manner, the outer end of the tilting end props upwardsand supports the outward-tilting bar, the inner end of the tilting plate props upwards and supports the inward-tilting bar, and the hearth and the lift fire tray are lifted relatively; and the lower end of the cavity cover is connected with a diverter, the upper part of the diverter is provided with a gas transmission conduit, the lower part of the lift fire tray is provided with a guide sleeve, and the gas transmission conduit is arranged in the guide sleeve to form a sliding guide pair. The invention has the advantages of simple and reasonable structure, safety, environment protection, energy conservation, no noise in the lift process, manufacturing materials saving and light overall quality, and is suitable for pans in various specifications.
