ABSTRACT:
An inflating device is provided with an air nozzle having two connectors of different specifications and engageable with inflation valves of different specifications. The air nozzle is composed of a shell, a distribution valve chamber located in the shell, an obstructing body located in the distribution valve chamber, and two connectors in communication with the distribution valve chamber. When one of the two connectors is engaged with the inflation valve of an object to be inflated, another one of the two connectors is idled such that air is prevented from entering the idled connector by the obstructing body. As the connector at work is disengaged with the inflation valve of the object, the obstructing body is capable of returning to its original position in the distribution valve chamber which is devoid of air.
