Driven by the first motor, the installation cylinder rotates, driving the material distribution plate to rotate, thereby adjusting the position of the fuel in the interior space of the fuel tank. The fuel on the inner side of the space communicated with one of the connecting pipes in the fuel tank will enter the installation box. Driven by the second motor, the connecting shaft rotates, driving the spiral blade to rotate. Under the conveyance of the spiral blade, the fuel is conveyed upward and sent to the combustion chamber through the feeding pipe.
