ABSTRACT:
A locking mechanism for use in a tension providing device. The tension providing device has a first shaft with a threaded end portion disposed within the interior of a cylindrical casing and a second end with a slit groove formed therein. A second shaft of the tension providing device has a threaded end engaged with the threaded end of the first shaft and an end protruding from the casing for providing tension. Rotation of the first shaft by a spring results in translation of the second shaft with respect to the casing. The locking mechanism includes a stopper pin removably secured in a lid of the casing at a position spaced from the axis of the first shaft. The pin is movable into engagement with the slit groove to lock the first shaft.
