A stirrup pump is a type of manual pump commonly used for inflating items like bicycle tires and sports balls. It consists of a long vertical cylinder and a handle that pivots on a hinge, which allows the user to push and pull in a motion similar to using a stirrup. When the handle is pulled up, air is drawn into the cylinder, and when it is pushed down, the air is expelled into the item being inflated.
