Abstract
An adjusting method and a structure for a seat post of a bicycle are provided. The structure of the seat post includes an adjusting tube, four pulleys, a pushing member, a main tube, an elastic member, and a cord. The adjusting tube is coaxially movably disposed in the main tube, while the pushing member is coaxially movably disposed in the adjusting tube and coaxially fixed with the main tube. One of the pulleys is pivotally disposed in the adjusting tube, and the other pulleys are pivotally disposed in the pushing member. Two of the pulleys inside the pushing member are movable along the pushing member. The cord is wound around the four pulleys. The elastic member is disposed in the pushing member and can push the pulleys to move. Pulleys moving along the pushing member push the adjusting tube moving outwardly form the main tube.
