[0033] The specific usage method and function of this embodiment:

[0034] When the utility model is working on engineering cost calculation, first screw the locking bolt 14. Since the locking bolt 14 is screwed into the threaded through hole of the box cover 9, the locking bolt 14 moves to the right along the threaded through hole of the box cover 9 until the end of the locking bolt 14 is out of the through hole on the left side of the storage box 1. Then the box cover 9 is flipped back to open, and then the convex column of the pulling rod 11 is inserted into the J-shaped slot of the box cover 9. The pulling rod 11 supports the box cover 9 for positioning at the flipping angle. Then the knob 18 is manually screwed. The knob 18 drives the active bevel gear 24 installed at the end of the transmission rod 21 to rotate, and the active bevel gear 24 drives the driven bevel gear 25 to rotate. The driven bevel gear 25 drives the bidirectional threaded rod 23 to rotate. Due to the object placement table 3 and the calculation auxiliary table 4 The threaded through hole of the convex column is respectively engaged with the forward threaded end and the reverse threaded end of the bidirectional threaded rod 23, and the bidirectional threaded rod 23 drives the object placement table 3 and the calculation auxiliary table 4 to move left and right. The object placement table 3 and the calculation auxiliary table 4 extend from the through slots on the left and right sides of the storage box 1 respectively, completing the deployment of the object placement table 3 and the calculation auxiliary table 4 on the storage box 1. The cost personnel lay the drawings on the drawing board 12, and then suck and press the pressure ruler 13 on the edge of the drawing board 12 to fix the position. The cost personnel put the calculation paper on the calculation table 20 for calculation. If it is necessary to remove the eraser crumbs generated during the calculation process, the calculation table 20 is manually turned over, and the eraser crumbs on the calculation table 20 slide into the through slot of the crumb collection box 17 by gravity. If working in a dim outdoor environment, the LED lamp tube 15 can be started, and the battery inside the battery compartment 26 supplies power to the LED lamp tube 15 for lighting.

[0035] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, and can be implemented as long as it can achieve its beneficial effects. The digital calculator 5, tablet computer 6, LED light tube 15, and battery compartment 26 used above are all common components on the market. When purchased and used, they can be used by simply connecting them according to the instruction manual purchased together, so they will not be repeated here.

[0036] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
