Threaded type valve connector

A valve connector comprising:

• a connecting member having a first axial hole penetrating through two opposite ends thereof, wherein the two opposite ends of the connecting member respectively form a connecting portion and an abutting portion, and wherein the connecting portion is adapted to connect an air tube of an inflation device;
• a threaded member having a second axial hole penetrating through two opposite ends thereof and a threaded portion formed in an inner periphery of the second axial hole, wherein the connecting member is inserted into the second axial hole to cause the abutting portion entering into the second axial hole;
• a joint member defining a first end and a second end opposite to the first end and having a third axial hole penetrating through the first and second ends, wherein the abutting portion passes through the third axial hole to selectively enter one of the first end and the second end, wherein the joint member forms a first threaded section at the first end and a second threaded section at the second end, wherein the first and second threaded sections are alternatively detachably connected to the threaded portion, wherein the third axial hole forms a first recess at the first end and a second recess at the second end;
• a first connection assembly disposed at the first end and adapted to connect a Presta valve, wherein the first connection assembly includes a first seal ring disposed at the first recess, and wherein the first seal ring is removably abutted against the abutting portion when the first threaded section is detachably connected to the threaded portion.
• a second connection assembly disposed at the second end and adapted to connect a Schrader valve, wherein the second connection assembly includes a second seal ring disposed at the second recess, and wherein the second seal ring is removably abutted against the abutting portion when the second threaded section is detachably connected to the threaded portion.
