Abstract

The present invention provides an improved structure of a tool box, wherein the tool box is made of plastic materials by blow-molding. Corners of the tool box are formed with retention recesses during the molding process. Protection pieces made of rigid material are embedded in the retention recesses before the molded tool box gets cooled down. Once the tool box is cooled down, the protection pieces are retained in the retention recesses. As such, by embedding protection pieces made of rigid material at corners of the tool box, the corners of the tool box are reinforced in structural strength whereby the protection pieces may take the place of the surfaces of the tool box to directly contact and collide a force applying surface for extension of the service life of the tool box.
