A using method of the repairing device for the screwed plug hole sealing end face comprises the steps that the threaded end of the threaded expansion mandrel is screwed into a proper position of a screwed plug hole, one end of the blade is close to the screwed plug hole sealing face, the expansion nut is tightened, and the radial fit clearance between the threaded end of the threaded expansion mandrel and a screwed plug hole thread is eliminated; when the sealing surface of the screwed plug hole is repaired, the feed adjusting nut is finely adjusted to push the thrust bearing, the thrust bearing pushes the cutter bin to perform axial displacement, so that the blade generates cutting feed amount, the convex block part of the driving joint is matched with the groove part of the cutter bin, the driving joint is rotated, the cutter bin is rotated, and the cutter bin drives the blade to rotate; cutting and repairing the sealing surface of the screwed plug hole by a blade; the problems that a traditional repair mac
