Due to the technical feature that the lifting shaft mounting seat includes a seat body that can be installed on a fixed base, two coaxial fixed shaft tubes are fixed on the seat body, and the two fixed shaft tubes are respectively connected to the rotating shaft tube shaft seal from both ends of the rotating shaft tube, so that a steam channel connected to the inside of the rotating shaft tube is formed between the two fixed shaft tubes, which makes the product production and assembly more convenient, and the steam channel resistance is smaller, and the exhaust is smoother. Due to the technical feature that the fixed shaft tube is inserted into the rotating shaft tube, sealing grooves are respectively provided at the two ends of the rotating shaft tube and the fixed shaft tube, and a sealing rubber ring is installed in the sealing groove to prevent steam from axial leakage in the radial gap between the rotating shaft tube and the fixed shaft tube, so that the sealing effect between the fixed shaft tube and the rotating shaft tube is better. Since the seat body and the fixed base are sheet metal seat body and sheet metal fixed base made of steel plate by laser cutting and bending, and the sheet metal seat body and the sheet metal fixed base respectively have the technical features of seat body connection plane and base connection plane for docking, the product production and processing are more convenient and the cost is lower. Since the seat body and the fixed base are movably connected by a connecting piece or a connecting structure, the installation of the pot cover is more convenient.Due to the technical features that the connecting piece is a connecting card, a connecting card fixing port is opened on the base connecting plane, and a connecting card hanging port is opened on the base connecting plane, not only the production cost is reduced, which is conducive to large-scale mass production, but also the connection and fixing effect of the base and the fixed base is better, and the connection and fixing can be completed by one plug and one drop, which is more convenient to operate. Due to the use of two fixed ear plates perpendicular to the base connecting plane provided on the base, a fixed shaft tube mounting hole is opened on the fixed ear plate, and a welding folding piece for welding and fixing the fixed shaft tube and the fixed ear plate is provided on the edge of the fixed shaft tube mounting hole, the assembly of the fixed shaft tube is more convenient.
