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.

[ What is claimed is:] [1.]1. An air valve connection head of an inflation device provided with an air storage bottle, said air valve connection head comprising:a housing provided with a receiving compartment which is provided at one end thereof with an engagement port, and at other end thereof with a through hole, said housing further provided with an insertion hole perpendicular to said receiving compartment and extending from a surface of said housing to the proximity of said receiving compartment for receiving a nozzle of the air storage bottle, said housing further provided with an air hole extending from an inner end of said insertion hole to said receiving compartment;a penetrating member provided with a pointed portion and disposed in said insertion hole such that said pointed portion faces an outer end of said insertion hole whereby said pointed portion is used to pierce a sealed end of the nozzle of the air storage bottle;a valve member movably disposed in an inner end of said insertion hole and provided with a protuberance facing said air hole, said valve member being forced by the compressed air in the air storage bottle to remain at an innermost end of said insertion hole such that said protuberance obstructs said air hole;an elastic annular block provided with a through hole and disposed in said receiving compartment such that said through hole is opposite to said engagement port;a press member movably disposed in said receiving compartment such that an inner end of said press member urges said annular block, said press member provided with a cavity opposite to said through hole of said annular block, a guide hole extending from a surface thereof to said cavity, and an inclined plane opposite to air hole whereby said inclined plane forces said valve member to displace toward said insertion hole at the time when said press member displaces toward said annular block; anda handle pivoted at one end to said housing such that said handle is swiveled to push via said through hole said press member.
