这是一项利用自行车自身构件作打气筒的实用新型专利。它将自行车车座下部分进行巧妙改造,即以车座兼作打气把手,下部一端装有活塞推杆,车座下的支撑钢管兼作打气筒简体,简体下部开有单向阀门,外接打气软管坎气门总接头。结构简单(见附图),使用方便,寿命长,省心省力,一物多用。 This is a use of bicycle components as a pump utility model patents. It cleverly remodels under the bicycle seat, that is, the bicycle seat also serves as a cheerleading handle, the lower end is equipped with a piston push rod, the supporting steel pipe under the seat serves as a simple inflator, the simplified lower part is provided with a one-way valve, Fork valve total connector. Simple structure (see photo), easy to use, long life, worry and effort, a multi-purpose.
