The driven gear ring is rotatably connected and installed above the lifting support frame. On both sides of the lower part of the lifting support frame, frame lifting cylinders are provided in a matching manner. At the center position below the driven gear ring, a positioning base is fixedly provided. In the arc-shaped groove of the positioning base, a liquefied gas cylinder body is placed. On the outer side of the liquefied gas cylinder body, a clamping plate is provided. The clamping plate is connected to a clamping seat through a clamping electric telescopic rod".
