The present invention provides a pay-out and take-up device for a tightener in the mechanical field. The pay-out and take-up device of the invention includes a casing fixedly connected to the side of the holder and a worm, a worm axis and a worm wheel set within the casing, in which the worm wheel is fixedly connected to the extension end of the belt axis, and the worm axis is provided on the side of the worm wheel and could move in the axial direction thereof within the casing, and the worm is covered on the worm axis and fixedly connected to the worm axis. A guide mechanism is placed between the casing and the worm or between the casing and the worm axis, in which the worm axis could move in the axial direction thereof when the worm axis rotates. The worm axis or the worm could be detached from the guide mechanism when the worm is engaged with the worm wheel. A power mechanism is further provided on the holder. A transmission mechanism is provided between the power mechanism and the worm axis for transmitting the power. The device of the invention has the benefits of simple operation, high binding efficiency and excellent applicability.
