The invention discloses an automatic air leakage adjustable pressure stabilizing device which comprises a body, a pressure guide joint, a conical drainage seat, a rubber sealing ring, a conical sealing cover, a spring, a spring upper pressure cover, a pressure cover and a pressure regulating rod. According to the automatic air leakage adjustable pressure stabilizing device, all components are used in a cooperative mode, the pressure regulating rod and the pressure cover can be used in a cooperative mode, the pressure is transmitted to the spring, and then the elastic potential energy of the spring is utilized to push the conical sealing cover to bear pressure, so that the automatic air leakage adjustable pressure stabilizing device can adjust the air leakage pressure at will according to the pressure in an oil tube, and the pressure in the oil tube is maintained to be stable.
