Description

Technical Field

[0001] The utility model relates to the technical field of metal products, and more specifically, to a power socket installation structure for taking power inside a box and a metal toolbox. Background Art

[0002] In places such as production and maintenance workshops, toolboxes are usually used to store various tools. Electric tools, such as electric screwdrivers, electric wrenches, vacuum cleaners, etc.; some electric tools are rechargeable electric tools with rechargeable batteries, which do not need to be plugged in during use and are flexible and convenient to use. However, for such electric tools, they need to be charged in time after use to ensure that there is sufficient power for normal work during operation. However, the charging time of electric tools is mostly during the worker's rest period. If the electric tools are placed outside the toolbox, the worker cannot watch them after leaving the work station, which may cause the loss of electric tools; if the electric tools are placed inside the toolbox, but since the charging cable needs to be connected to an external power source, the charging cable or the power cord of the power socket needs to extend out from the drawer opening or the box cover opening, blocking the closing of the drawer and the box cover, resulting in the toolbox being unable to be locked, and there is also a risk of loss of electric tools.

[0003] Therefore, it is necessary to improve the toolbox to solve the technical problem that the toolbox cannot be locked and stored when the electric tools are charged. Summary of the Utility Model
