ABSTRACT:
The present invention provides a universal connector for a pneumatic tool with unlocking by air flow. A directional locating member is mounted between the sleeve and the first coupler, or the pin-joint member, so the sleeve can be securely locked when located at the first position. Available at first and second positions, the second coupler of the universal connector can be positioned in the absence of aeration, or reset automatically after aeration, thus achieving unlocked by air flow purpose. This ability provides easier and convenient assembly or disassembly of the universal connector and pneumatic tool without needing any controlling members, thus guaranteeing improved ease-of-operation and higher applicability.
