Zusammenfassung:	The utility model discloses a spiral injection gun, which is used for injecting a sealing injection with an 'injection pressurized sealing technology' after a fluid conveying pipeline or a storage container leaks. A jacking steel ball of the spiral injection gun is arranged at the joint between an advancing and retreating screw rod and an injection rod; a return screw is arranged in the threaded hole of a rotary advancing and retreating screw rod; the advancing and retreating screw rod is connected integrally with the injection rod through the jacking steel ball and the return screw; and the output end of the spiral injection gun is provided with an internal thread nut. The spiral injection gun is an independent injection system, and a sealing injection can be injected into a sealing cavity of a leaking position under the rotating action of the advancing and retreating screw rod by means of labor force through a ratchet wrench or an ordinary wrench. A gun head is provided with an internal thread nut, so that
