Disclosed is a blind cord winder integrating with stopping control to allow open/close operation of the cordless blind to lift or lower the cordless blind at any positions according to user's needs. The winder primarily comprises a spool installed inside a first compartment, a force-feedback mechanism, and a braking cushion mechanism installed inside a second compartment where the force-feedback mechanism is installed in a shaft cavity of the first compartment. The force-feedback mechanism includes a shaft sleeve and a volute spring. The braking cushion mechanism includes a friction ring, a friction spring, and a trigger sleeve. The friction ring is immovably installed inside the second compartment. The friction spring is tightly plugged into the friction ring and has an extrusion end for the trigger sleeve to trigger friction variation in a single directional rotation of the trigger sleeve. |
