Abstract
A slat-lifting mechanism of the Venetian blind is composed of a slat set, a pull set, a slat pull cord, and a locating set. The slat set has a plurality of slats. The pull set has a pull cord member and a spring retrieving unit which is linked with the pull cord member. The slat pull cord has one end that is put through the slat set, and other end that is fastened with the pull set. The locating set is disposed in the traveling path of the slat pull cord and is capable of bringing about a friction resistance which is greater than a retrievable pull force of the spring retrieving unit for overcoming the pulling force of the slat pull cord, so as to control the pulling or the releasing of the slat pull cord. The slat set can be thus located by the locating set.
