The invention discloses a slip hanger capable of realizing automatic or manual independent excitation. A sleeve is mounted in a sleeve four way through the hanger; the slip hanger comprises a slip assembly and a sealing device assembly connected through a coupling screw, wherein an excitation ring is arranged in the sealing device assembly; an internal thread structure is arranged in the excitation ring; one end of the coupling screw is fixedly connected with the slip assembly; the other end of the coupling screw is in threaded connection with the lower end of the excitation ring; an internalring seal ring and an external ring seal ring are arranged on the internal and external sides of the excitation ring separately; and a cover plate is arranged above the excitation ring. Compared withthe prior art, the slip hanger has the benefits of having the self-excitation sealing function and manual excitation sealing function, being few in leaking path, simple in structure, convenient to operate, and reliable in sealing, providing fast and reliable sealing and hanging functions, ensuring site safety and saving the mounting time.
