Description

technical field [0001] The present invention mainly discloses a small foot pump, especially a small foot pump with an extension tube set. Background technique [0002] With the change of life style, people pay more and more attention to the quality of leisure life. Natural environments such as countryside and suburbs have become people's new favorites. Riding bicycles in the suburbs has become a new fashion for modern people, even in the urban jungle.

[0010] But the extension effect provided by this single-cut flexible pipe 14 is limited. For the small-sized pump that can be stepped on, when the user performs the filling operation, the user's body must be close to the pump, and the user's feet must be Stepping on the pedal 13, the user's hand must be held on the handle 30. In other words, the user's body and the pump are close to each other. When the length of the single-section hose 14 is too short, the user's body, hand The head and feet will interfere with the bicycle

Therefore, for a pump that can be stepped on, the operating space of the pump needs to be larger to avoid interference between the user's body, hands, feet and the bicycle. This kind of pump cannot increase the distance between the user and the bicycle. , it will make the user unable to operate the pump flexibly and carry out the gas filling operation
