The present invention relates to a storage device, and more particularly to a toolbox.
Generally, when fixing objects, drive tools (such as wrenches, sockets, screwdrivers or the like) are used to drive fasteners or connectors for assembling/disassembling. However, there are a variety of sizes and types of drive tools, so that toolboxes are often used for easy storage and carrying of the drive tools.
The conventional toolbox includes a plurality of plastic plates, the plurality of plastic plates are assembled by screws, which is advantageous for convenient and fast assembling. However, the screw is disposed through holes on the circumferential surface on one plastic and directly screwed to another plastic plate, so it results in a poor integrity and an unsightly appearance. In addition, no matter the portion of the plastic plate to which the screw is screwed is of a solid or hollow structure, it is easy to unscrew, detach or break, due to its low structural strength of the plastic material, when the toolbox is moved, dropped or subjected to external forces or impact.
