ABSTRACT:
A Venetian blind includes a control, a square transmission shaft joined to the control, an external tube, and a reel tube having an external spiral groove, along which a lift cord is wound; the external tube has two elongate protrusions parallel to an axis thereof on an outer side; the elongate protrusions define a tunnel in between, and have opposing gaps on the edges thereof, and they are formed with such a shape that a lengthways-extending aperture is provided between edges thereof; a tilt cord is passed over, and joined to the external tube with a middle knot thereof being detained in the tunnel of the external tube, and with two ends thereof being passed through the gaps of the elongate protrusions of the external tube; thus, the tilt cord will always move together with the external tube.
