The invention provides a folding framework of a folding three-wheel bicycle so as to meet the requirements that the bicycle is more flexible, lighter and more widely used, carried and stored, and the bicycle cannot fall during riding and stopping. Comprising an assembly (100), an assembly (200), an assembly (300), an assembly (400), an assembly (500) and a pin shaft (601), the assembly (100), the assembly (200), the assembly (300), the assembly (400) and the assembly (500) are connected with related pin shafts (601) at respective connecting positions in a matched mode through related bosses, clamping grooves and shaft holes which are matched with one another at the respective connecting positions, and a whole capable of relatively rotating between an unfolded state and a folded state around the pin shafts (601) at the respective connecting positions is connected. And the folding and unfolding device can be locked in an unfolding state or a folding state through related movable bolts, related pin holes and related positioning grooves which are mutually matched at respective connecting positions, and can be unlocked through related buckles at the respective connecting positions.
