[0002] As the name suggests, a toolbox is a container for storing tools and various household sundries. It can be used for various purposes such as production, household, maintenance, fishing, etc. It is widely used. It is divided into mobile and fixed types. The mobile toolbox is also the so-called tool cart.

[0003] Traditional mobile toolboxes are usually designed in a larger form. Although they can store many tools, they are also difficult to carry. This may cause inconvenience to users in some cases. For example, as a maintenance toolbox for aircraft such as helicopters and fighter jets, the larger mobile toolbox is not light enough and cannot be flexibly used in combat training. It is also more difficult to carry and is not portable enough. The toolbox does not have the function of retrieving the number and type of tools. If a tool is left inside the aircraft, it is easy to cause an accident. In addition, the operator needs to open the box to check how many tools and what types are left in the toolbox, which is a cumbersome process. Most toolboxes stack tools together, which not only makes it difficult to find and use them, but also makes it easy for tools to collide and wear each other. At the same time, the existing toolboxes are more cumbersome in the locking and unlocking steps, which wastes more time and affects work efficiency. Utility Model Content
