[0020] Step 6: When performing complex mathematical operations and information processing, the computer components inside the protective box can be started, and the lifting cylinder group will lift the mobile box carrying the computer screen and the main box until the computer screen and the main box are completely exposed on the main table, which is convenient for the engineering cost staff to operate;

[0021] Step 7: When the computer components are not in use, they will be stored in the protective box, and the drive motor will be started to control the bidirectional screw and threaded sleeve to operate, driving the symmetrically distributed clamping plates with buffer rubber pads to stably clamp the computer screen in place. The benefit of this design is that it greatly improves the stability of computer-related accessories, facilitates transportation and relocation, and can effectively prevent dust, moisture, physical shock and other environmental factors from damaging computer equipment.

[0022] Beneficial effects of the present invention:

[0023] Compared with the traditional workbench with a fixed structure, the present invention can expand the usable area on both sides of the main table through simple assembly steps, thereby improving the flexibility of the workbench, reducing congestion in the working area, and facilitating movement and transportation. By optimizing the traditional legs of the workbench into files, and setting hidden drawers on the table top, and adding a detachable multi-functional back panel, various engineering cost calculation files can be effectively managed and stored, which is conducive to on-site instant communication and discussion, and improves the functionality of the workbench, making it more suitable for complex engineering cost tasks. The computer component adopts a liftable design, which is raised when in use and stored in a protective box when idle, and the computer screen is stably clamped and positioned. The advantage of this design is that it greatly improves the stability of computer-related accessories, facilitates transportation and relocation, and can effectively prevent dust, moisture, physical shock and other environmental factors from damaging computer equipment.
