Abstract
A window blind has a headrail, a bottom rail, and multiple slats provided below the headrail. In the headrail, an adjusting shaft and an auxiliary adjusting module are provided and connected. A ladder string is connected to the adjusting shaft, whereby the adjusting shaft adjusts a shape of the ladder string to tilt the slats and the bottom rail. A first cord and a second cord extend out of the headrail and are connected to opposite sides of the bottom rail. When the adjusting shaft drives the slats to tilt in a direction, the auxiliary adjusting module releases the first cord out of the headrail and retracts the second cord into the headrail. When the slats are tilted in an opposite direction, the auxiliary adjusting module retracts the first cord into the headrail and releases the second cord out of the headrail.
