The invention provides a tool-free handlebar quick-mounting structure, and relates to the technical field of bicycles. The tool-free handlebar quick-mounting structure comprises a handlebar with a clamping groove formed in the side wall; the bottom inserting end of the stem is suitable for being inserted from the top opening of the vertical pipe, and a movable channel penetrates through the side wall of the vertical pipe; the positioning structure is assembled on the vertical pipe and comprises a sliding sleeve and a movable body, the sliding sleeve can be slidably connected to the outer side of the vertical pipe in a sleeving mode in the vertical direction, the movable body is movably arranged in the movable channel, an extrusion part is arranged on the inner wall of the sliding sleeve, and the sliding sleeve has an unlocking position and a locking position in the vertical direction; when the sliding sleeve is located at the unlocking position, the stem is inserted into the vertical pipe, when the clamping groove of the stem and the movable body are transversely aligned, the sliding sleeve slides to the locking position from the unlocking position in the vertical direction, the extrusion part of the sliding sleeve extrudes the movable body to transversely move inwards in the movable channel, and the movable body partially extends into the inner wall of the vertical pipe to be clamped to the clamping groove to form clamping fit. The defect that in the prior art, a stem is inconvenient to assemble is overcome.
