The end of the pull rope for lifting the venetian blind is fixedly connected to the motor shaft of the winding motor 211, and the partition ring 212 is arranged to divide the area of the motor shaft to avoid the mutual entanglement of different pull ropes when the motor shaft of the winding motor 211 rotates to wind the pull rope.
