TIRE CHOCK LOCK

A rotatable tire chock lock is provided. The rotatable tire chock lock rotates its threaded rod to make its rotator face towards a user, thereby making it convenient for manual operation and using power tools. The rotator of the threaded rod is rotated to raise or lower an upper nut slider and a lower nut slider. Therefore, a quadrangular support structure that is connected between the two nut sliders can expand or retract to make support plates that are connected to the quadrangular support structure fit with tires located at the same side, thereby tightening the tires.
