At the same time, the booster wheel 2 provides support and sliding, reducing the resistance and friction to the wheel. When the wheel is fixed, the aircraft is dragged by connecting the buckle on the base 1 to the tractor, so that the booster temporarily replaces the function of the wheel with a flat tire. After arriving at the maintenance site, the direction of the reversing pressure rod 4021 is changed by manually operating the reversing pressure rod part 4, and the functions of the return oil port and the oil suction port of the pump body 403 are switched, so that the hydraulic oil flows back to the oil tank, thereby completing the work of the booster.
