2 Disclosed is a blind cord winder integrating with stopping control to allow 3 open/ close operation of the cordless blind to lift or lower the cordless blind at any 4 positions according to user's needs. The winder primarily comprises a spool 5 installed inside a first compartment, a force-feedback mechanism, and a braking 6 cushion mechanism installed inside a second compartment where the 7 force-feedback mechanism is installed in a shaft cavity of the first compartment. 8 The force-feedback mechanism includes a shaft sleeve and a volute spring. The 9 braking cushion mechanism includes a friction ring, a friction spring, and a trigger 10 sleeve. The friction ring is immovably installed inside the second compartment. 11 The friction spring is tightly plugged into the friction ring and has an extrusion end 12 for the trigger sleeve to trigger friction variation in a single directional rotation of 13 the trigger sleeve. c::; CZ) cy:) cq Ln CY'D C:) C-1 Ln CYD C=) -- 4 ---------- C=) CrD - ---------------------------- cq cq ---.
