1. A threaded fixing structure, comprising:
an inflating valve,
a base and
a sealing ring,
wherein the inflating valve is provided with a first connecting face, the base is provided with a second connecting face, the inflating valve is in threaded connection with the base along a rotation axis which are perpendicular to the first connecting face and the second connecting face, the sealing ring is arranged between the inflating valve and the base,
wherein after the threaded connection along the rotation axis between the inflating valve and the base is completed, the first connecting face and the second connecting face are attached, a fixed protrusion portion is formed on the second connecting face perpendicular to the rotation axis by punching, and the fixed protrusion portion is sunken into the inflating valve to form a fixing groove in the first connecting face perpendicular to the rotation axis to limit the relative rotation between the base and the inflating valve.
