Description

Combined toolbox

The invention relates to a combined toolbox.

Generally, a driving tool (such as a wrench, a socket, a screwdriver bit, etc.) drives a fastener or connector to disassemble an object when fixing an object. These driving tools come in many sizes and types. To facilitate storage and carrying, tool boxes are often used for storage.

The conventional toolbox includes a plurality of plastic plates, and the plurality of plastic plates are assembled by screws, which has the advantages of convenient and fast assembly. However, when assembling and connecting, the screw passes through one plastic plate and is directly screwed to the other plastic plate. No matter the screw connection is solid or hollow, the structural strength of the plastic material is relatively low. , When subjected to external forces such as moving, falling, or impact, the screw-locked joint part of the plastic plate and the screw is easily loosened, separated or broken.

Therefore, it is necessary to provide a novel and progressive modular toolbox to solve the above-mentioned problems.
