Abstract
An inflation nozzle has a cylindrical receiving cell which is provided with an air inlet, an open end, and an engagement port for engaging the air valve of an inflatable object. The receiving cell contains a first elastic annular block, a seat block, a second elastic annular block, and a press block. A handle is pivoted to the open end for pressing the press block. The seat block has a through hole in communication with a through hole of the second elastic annular block. The seat block is provided with a rotary member which has a curved portion and a notch. A coil spring enables the curved portion and the notch to remain at an angle at which the curved portion and the notch face the engagement port. When the engagement port is engaged with an air valve of the U.S. specification, the valve tube of the air valve is inserted into the notch to arrest the rotary member such that the valve bar of the air valve is pressed by the curved portion to allow the passage of air. When the engagement port is engaged with an air valve of the French specification, the rotary member is pushed to turn such that the valve bar of the air valve is pressed by the press block to allow the air passage.
