A tool box has box which pivotally installed with a transparent cover. A hook extends from the cover toward the box. The box has a concave portion corresponding to the hook for being buckled by the hook. The box has a spacer. The spacer spaces the interior of the box into an upper receiving chamber and a lower receiving chamber. The lower receiving chamber has an opening penetrating the box at a side with respect to the concave portion. A disk is placed into the lower receiving chamber from the opening. The concave portion of the disk corresponding to the box has a stop plate. The thickness of the stop plate is smaller than the depth of the concave portion. Thereby, the hook of the cover buckles the concave portion and at the same time it resists against the stop plate for fixing the disk.
