The retaining ring 14 is fitted onto the hanging rod 13 to limit the range of motion of the tools. Users can hang tools on the hanging rod 13 as needed and fix their position using the retaining ring 14 to prevent the tools from shaking or falling off during transportation.

[0028] Drawer assembly 15 is located on the front side of the cabinet 1 and is used to store small tools or accessories. Drawer assembly 15 includes a drawer body and guide rails. The drawer body has grooves on both sides that cooperate with the guide rails to allow the drawer to slide along the guide rails. The end of the guide rails has a stop to prevent the drawer from being fully pulled out. The user can open the drawer by pulling out the drawer body to take out the required tools or accessories, and then push it back into place after use.

[0029] The power interface and lighting device are located on the rear side of enclosure 1, providing power support and lighting for maintenance work. The power interface is connected to an external power source via a wire. The lighting device includes an LED light and a switch. The LED light is fixed to the top edge of enclosure 1, and the switch is installed on the side of enclosure 1 to control the LED light's on / off state. When maintenance personnel need to work in low-light environments, they can turn on the LED light via the switch to provide sufficient illumination for the work area.

[0030] The connection and positional relationships between the components are as follows: The main body 1 is connected to the expansion module 2 via a slide rail and locking assembly at its top. An adjustment mechanism is provided on the inner side wall to adjust the space of the partition cavity 7. The bottom is connected to the base 9 via a lifting assembly 8 for height adjustment. A tool rack 12 is mounted on the side wall of the body 1, a drawer assembly 15 is located on the front of the body 1, and the power interface and lighting device are located on the rear of the body 1. All components are tightly fitted together via mechanical connections or threaded fasteners to form a complete toolbox system.

[0031] In practical applications, this toolbox can be used for tool storage and repair operations during automotive repair. For example, in a repair shop, users can adjust the height of the compartment 7 according to the tool specifications to categorize and store different types of tools. When the working area needs to be expanded, the folding panel 3 can be pulled out from the top of the box 1 and locked, while the support frame 4 ensures its stability. If the height of the working environment is not suitable for the current operation, the overall height of the box 1 can be adjusted using the lifting assembly 8 to meet ergonomic requirements. In addition, the tool rack 12 can hang commonly used wrenches or screwdrivers for quick and easy access; the drawer assembly 15 can be used to store small accessories such as nuts or washers. In low-light conditions, users can turn on the LED lights to provide illumination for the work area. These designs make the toolbox highly flexible and adaptable in practical use, meeting the needs of automotive repair personnel for tool storage and operation.

[0032] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0033] First, in the repair workshop, the user needs to adjust the height of the partition cavity 7 according to the specifications of the tools. Specifically, the user needs to loosen the bolts on the positioning piece 6, allowing the sliding sleeve to move up and down along the adjusting rod 5. Once the sliding sleeve has moved to the desired height, the bolts are tightened again to fix the sliding sleeve onto the adjusting rod 5. At this point, the side wall of the partition cavity 7 connected to the sliding sleeve shifts, thereby changing the height of the partition cavity 7. For example, if a longer wrench needs to be stored, the height of the partition cavity 7 can be lowered; if a shorter screwdriver needs to be stored, the height of the partition cavity 7 can be increased. Through these steps, the user can flexibly adjust the spatial layout of the partition cavity 7 according to actual needs to meet the storage requirements of tools of different sizes.

[0034] Secondly, when maintenance work requires expanding the working area, the user can pull out the folding plate 3 from the top of the box 1 in the expansion module 2. Specifically, first, release the locking assembly, allowing the folding plate 3 to slide along the slide rail. Once the folding plate 3 is fully extended, the support frame 4 automatically unfolds and provides stable support, ensuring the folding plate 3 remains horizontal. Subsequently, the user can use the locking assembly to secure the folding plate 3 in the designated position. This process expands the toolbox's working area, providing maintenance personnel with a larger operating space.

[0035] Next, if the height of the working environment is not suitable for the current operation, the user can adjust the overall height of the box 1 using the lifting assembly 8. Specifically, pull the locking pin to disengage it from the positioning hole of the telescopic column 10, and then move the telescopic column 10 along the guide groove of the base 9 to the desired height. After releasing the locking pin, the spring pushes the locking pin back into the new positioning hole, completing the height adjustment. This design allows users to flexibly adjust the height of the toolbox according to ergonomic requirements or the actual needs of the work scenario, improving operational comfort and convenience.

[0036] Furthermore, during maintenance, users can quickly access commonly used tools via the tool rack 12. Specifically, tools are hung on the hanging rod 13, and the movement of the tools is restricted by the limiting ring 14. The limiting ring 14 can be adjusted according to the size of the tool to prevent it from shaking or falling off during transportation. Meanwhile, the drawer assembly 15 can be used to store small accessories, such as nuts or washers. Users simply pull the drawer body to open it along the guide rails, retrieve the required tools or accessories, and push it back into place after use. This design not only improves the efficiency of tool categorization and storage but also facilitates quick access to necessary items for maintenance personnel.

[0037] Finally, in low-light environments, users can provide ample illumination to the work area using a lighting device. Specifically, pressing the switch mounted on the side of the housing 1 activates the LED light. The LED light, fixed to the top edge of housing 1, provides uniform illumination to the work area. The power interface connects to an external power source via a power cord, ensuring the lighting device functions properly. This design solves the lighting problem for maintenance work in low-light conditions, further enhancing the toolbox's functionality and practicality.

[0038] Through the above steps, the toolbox of this utility model demonstrates high flexibility and adaptability in practical applications. The coordinated operation of its expansion module, adjustment structure, lifting assembly, tool rack, drawer assembly, and other components effectively solves the problems of fixed internal space and insufficient expandability in existing toolboxes, significantly improving the toolbox's practicality and adaptability.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
