摘要： A manually operated pump for supplying air to a bicycle comprises an outer tube (3) with one end closed and the other end open; a core tube (4) which can slide in the outer tube (3) and is provided with a piston assembly (2) on one end; and a hose (5) which can slide in the core tube (4). One end of the hose (5) is connected with an air needle (6), and the other end of the hose (5) is connected with an air nozzle assembly (1). The piston assembly (2) comprises a piston (21), a piston ring (23), and a one-way valve (22) communicating with the core tube (4) and the outer tube (3). An end socket (7) is provided on the other end of the core tube (4). A narrowing port (17) is formed in the end socket (7) of the core tube. A foot stand (8) is hinged on outer side of the end socket (7) of the core tube. The air needle (6) is provided with a head matching with the narrowing port (17). The pump of the present invention has a compact structure and is convenient for using.
