A rope tensioner which includes a take-up reel and a take-up spring. A damping assembly is configured for the take-up reel and includes a follower gear, a damping gear and a damping removal component. The follower gear is configured to rotate synchronously with the take-up reel. The damping gear is movably configured and keeps in damping engagement with the follower gear. The damping removal component is movably configured, and when an external force for removing the damping engagement is applied to the damping removal component, the damping removal component promotes the damping gear to disengage from the follower gear to relieve or remove the damping engagement. The situation where a hook rebounds under the action of inertia when a rope is taken up and hits against products and even causes injuries to users is avoided.
