Screw-in valve connector

A screw-in valve connector, comprising:

• a stationary connecting pipe including a pipe body and a drive portion, wherein the pipe body includes an air intake portion at one end, an air discharge portion at another end thereof, and a receiving hole running through the air intake portion and the air discharge portion, the air intake portion includes an air inlet in communication with the receiving hole, and the drive portion is located on an outer annular surface of the pipe body;
• an elastic member disposed in the receiving hole, and including a press end pressed against the air intake portion and a force-receiving end opposite the press end;
• a stop including a lower end inserted in the force-receiving end, a stop end opposite the lower end, an engaging portion located between the lower end and the stop end to stop against the force-receiving end, and an air passage penetrating the lower end and the stop end, wherein the elastic member provides an elastic force for the engaging portion to push the stop toward the air discharge portion, and the air passage is in communication with the receiving hole;
• a positioning ring sleeved onto the stop end to abut against the engaging portion, and including a first threaded hole for threaded connection of a French valve;
• and
• a rotary ring pivotally connected to the air discharge portion, and including a second threaded hole for threaded connection of an American valve;
• wherein the stationary connecting pipe has a straight shape and further includes a cylindrical pipe inserted in the receiving hole, the cylindrical pipe includes:
• an air hole axially penetrating the receiving hole and provided for accommodation of the elastic member;
• a cylindrical end inserted in the air hole to press against the press end of the elastic member;
• and a pipe connecting member which includes:
• a pipe connecting end, an airtight seal end opposite the pipe connecting end, and a pipe connecting passage penetrating the pipe connecting end and the airtight seal end, the airtight seal end is airtightly disposed in the receiving hole and abutted against the cylindrical end of the cylindrical pipe, and the pipe connecting end extends out of the air inlet to communicate with the receiving hole.
