Abstract

The present invention relates to an air pump head that can readily clamp an air valve, comprising an outer casing and a packing device. The outer casing comprises an outer tube and a pull member. The outer tube is formed with a through channel extending therethrough. The pull member is mounted to the outer tube in a manner of being rotatable between a released position and a clamping position. The packing device is arranged in the through channel. The clamping device comprises a push seat and an end of the push seat abuts against the pull member. The push seat is recessed with a receiving hole. The packing device comprises a first clamping member and a second clamping member arranged on the push seat. When the pull member is at the clamping position, the first clamping member and the second clamping member form therebetween a distance that define a clamping width, wherein the clamping width is less than an outside diameter of an outer wall of the air valve. As such, the air pump head may clamp the air valve to prevent the air valve from detaching during an air pumping process.
