The invention relates to the technical field of public transport means, in particular to a pull ring for public transport means, which comprises a pull ring shell and a fixing sleeve fixedly connected with the inner wall of the public transport means, the inner wall of the pull ring shell is rotationally connected with a positioning ring through a clockwork spring. A nylon belt with one end penetrating through the pull ring shell to be connected with the fixing sleeve is wound outside the positioning ring. The positioning ring is connected with two ring plates, and the nylon belt is located in a cavity formed by the two ring plates and the positioning ring. Ratchet teeth are annularly arranged on one side of the annular plate; a lever is rotationally connected in the pull ring shell, one end of the lever is provided with a clamping block meshed with ratchet teeth on the ring plate, and the other end is provided with a button; the clamping block is connected with the pull ring shell through a reset spring. When the reset spring is in a natural state, the clamping block is meshed with the annular plate, and the button protrudes out of the pull ring shell. When the reset spring is in a contraction state, a distance exists between the button and the annular plate. The height of the pull ring can be adjusted.
