The invention relates to a clamp ring type locking device of a bicycle seat tube. The clamp ring type locking device of the bicycle seat tube is composed of clamp rings, clamp grooves and bottom grooves. The clamp rings, the clamp grooves and the bottom grooves are matched with one another. Sections of the clamp grooves are formed at the sides of the bicycle seat tube symmetrically, and the clamp grooves are in a sunken inward shape. The elastic clamp rings are clamped to the clamp grooves. Handles and buttons are arranged on the clamp rings, pinching the buttons by a hand can enable the clamp rings to open outward and leave the clamp grooves, the bottom grooves are formed in the upper ends, corresponding to a bicycle tube, of the clamp rings, the clamp grooves entering the clamp grooves can exactly fall into the bottom grooves, and thereby the purpose of fixing the seat tube is achieved.
