Abstract
An air pump nozzle has a receiving compartment with an open end where a handle is pivoted. The receiving compartment is provided at other end thereof with a holding mouth involuting a large diametric end of fish-eye through hole of an elastic holding member which is pressed against by a press member having a receiving hole in which a pushing member and a valve urging member are disposed. In operation, the inflation valve of the U.S. type is received in the through hole of the holding member. The handle is swiveled to force the pushing member to actuate the press member to press the holding member to deform so as to hold securely the inflation valve. The inflation valve is opened up by the valve urging rod which is pushed by the pushing member. The inflation valve of the French type passes the holding member to push the valve urging rod to a stop point. The holding member is deformed to hold securely the inflation valve which is opened up by the valve urging rod which is pushed by the pushing member. As the inflation valve is disengaged, the pushing member and the valve urging rod are forced back to their original positions by an elastic member and a magnetic member.
