[0002] As a tool box in a broad sense, it includes containers used to hold parts in the assembly process of manufacturing enterprises. Due to differences in products, the number of parts used in the assembly process will vary, ranging from 3-5 to dozens. In order to facilitate the picking of parts, a tool box that occupies little space and is easy to use is needed.

[0003] In the prior art, a tool box is generally provided with a plurality of storage slots for placing different tools. In workshop operations, not only are the tools required to be neatly stacked, but also different tools are required to be randomly matched and stacked together according to the different operation requirements of the operator to ensure that they are convenient to take and put during the operation. However, there are many types of tools and the tool specifications and sizes are different. It is impossible to match different operation functions and different types of tools and store them in the same tool box at the same time, so that it is quite inconvenient to store and use them. If several distinguishable tool boxes are set, it will take up a large space, and stacking them together will cause overall instability. Moreover, multiple structures are required to achieve stacking up and down and left and right, which increases production costs. When users operate, they need to increase the operation steps, thereby affecting work efficiency. Based on the current situation, a combined tool box is urgently needed to solve the problem of a large number of tools in workshop work and the inconvenience of collection and use, reduce the user's operation steps, make it simpler to use, and improve work efficiency. Therefore, it is necessary to upgrade and transform the existing tool box device to overcome the existing problems and shortcomings and provide a combined tool box. Utility Model Content
