[0002] A toolbox is a box used to store tools, usually made of materials such as wood, metal, and plastic. Inside the toolbox, there are usually various-sized and -type grids or drawers for classifying and storing tools. A toolbox is a very practical item that can help people better organize and carry various tools.

[0003] There is a device with the publication number CN201009235Y, a convenient disassembly and assembly type combined toolbox. The box body is composed of left and right side plates with "L"-shaped frames, bending-edge limit guide strips, flap slide rails, drawer guide rails, and assembly holes on the upper part, a rear side plate with assembly holes and an inner-folded "L"-shaped support / assembly strip with mounting holes on the upper part, an upper top plate with an "L"-shaped assembly strip with mounting holes on the upper part, an "L"-shaped assembly strip with mounting holes and an "L"-shaped decorative cross strip, a lower bottom plate with bottom foot mounting holes at the corners, and a bending long strip-shaped anti-collision strip with a limit guide groove assembled together; the four corners of the box cover are set in an "R" shape that fits the anti-collision strip sleeve assembly. Removing the box cover, removing the anti-collision strip and screws can disassemble the whole box into independent components that are convenient for stacking with each other and can reduce the packing volume by more than 2 / 3, which not only helps to save the materials of the packing box, but also brings extremely positive economic effects to the vehicle load in transportation and the storage in storage and collection.
