Aircraft fuel tank sediment discharging tool

The utility model discloses an airplane fuel tank sediment discharging tool which comprises a casing pipe, a pin shaft is arranged at one end of the casing pipe in a radial penetrating mode, an anti-skidding portion and an ejector rod are arranged on the periphery of the casing pipe, one end of the ejector rod is in radial threaded connection with the pin shaft, the other end of the ejector rod is exposed out of the casing pipe, and the casing pipe of the airplane fuel tank sediment discharging tool is connected with the ejector rod through the pin shaft. The sediment discharging valve of the oil tank is triggered through the ejector rod, and discharged liquid is drained into the sleeve through the ejector rod and then led into the collector through the sleeve or the ejector rod. The ejector rod is withdrawn after collection, and the ejector rod is taken away after the sediment discharging valve is closed, so that non-contact sampling collection is realized, the sampling collection efficiency is improved, pol
