Abstract
An air valve connection head is designed to work with an inflation device comprising an air storage bottle in which the compressed air is kept. The air valve connection head comprises a housing which is provided with a receiving compartment, an elastic annular block disposed in the receiving compartment, and a press member disposed in the receiving compartment such that the press member urges the annular block. The housing is further provided with an insertion hole and an air hole extending from the insertion hole to the receiving compartment. A valve member is movably disposed in the insertion hole for obstructing the air hole. A handle is pivoted to the housing such that the handle is swiveled to push the press member to cause the elastic annular block to deform to lash the air valve of an inflatable object. As the press member is pushed to displace, an inclined plane of the press member extends into the receiving compartment to push back the valve member so as to relieve the air hole of being obstructed by the valve member.
