Abstract: A tool cabinet comprises a front frame; a rear frame; a door panel; a back panel; a side panel; a shelf; a top panel; a bottom panel; and a supporting leg. The tool cabinet is combined with the front frame and the rear frame thereof serving as the main body, such that the structure of combined tool cabinet is stable, the manufacturing process thereof is improved, the components thereof are properly spaced, and the tool cabinet can be disassembled easily. As the tool cabinet is combined from various components, the packaging thereof is reduced by two third, significantly reducing the transportation cost and resources consumed.
