Zusammenfassung:	The utility model relates to the technical field of hovering locking structures, in particular to an oil-gas hovering locking structure which comprises an adjusting valve element, a first guide head and a first sealing groove provided with a first assembling sealing ring. The guide head II is provided with a sealing groove II for assembling a sealing ring II, and the diameter of the guide head IIis the same as that of the guide head I; one axial end of the necking body is connected with one axial end of the first guide head, the other axial end of the necking body is connected with the secondguide head, and the diameter of the necking body is smaller than that of the first guide head. The structures of the adjusting valve element and the piston are improved; a piston with a complex structure is changed into a piston which is simple in structure and convenient to process; the piston and the adjusting valve element are integrated, the sealing groove is additionally formed in the adjusting valve element, the pos
