A curtain control assembly includes a shaft in which a torque rod and a control unit are received. The curtain is wrapped around the shaft. The control unit has a frame from which a tubular portion extends. The tubular portion has a polygonal protrusion. An end support is located in the frame and has a hook which is hooked to the control unit. A bead-chain disk is mounted to the tubular portion. A mount is mounted to a sleeve of the bead-chain disk. A connection member is fixed to the torque rod and a polygonal recess is defined in the connection member. The protrusion is engaged with the recess. A screw extends through the connection member, the tubular portion and is fixed to the end support. The feed-back of torque from the torque rod is shared by the polygonal recess and protrusion to protect the hook from being broken.
