Description

technical field [0001] The invention relates to a foot-operated pumping device. Background technique [0002] There are usually two ways to inflate the tires, one is the automatic inflating method and the other is the manual inflating method. The automatic inflating usually uses an air compressor to inflate the tires. The air compressor must have electricity to work, so the air The scope of use of the press is relatively limited. Compared with automatic pumping, manual pumping is more convenient to use and is not limited by electric energy. However, the existing manual inflating mode is usually a hand-pressed inflating device, and the hand-pressed inflating device is to make the piston rod drive the piston to extrude the gas by hand pressing the piston rod so as to inflate the tire. When using the hand-pressed pumping device, a person needs to bend over to pump the pump, which is inconvenient to use and has a high working intensity. [0003] This shows that the existing ha...
