[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: an auxiliary device for civil engineering project cost budget, including a workbench 1. A placement groove 2 is provided inside the workbench 1. A sliding button 3 is slidably connected inside the workbench 1. A limiting block 4 is slidably connected inside the sliding button 3. One side of the outer wall of the limiting block 4 is fixedly connected with a spring 5. One end of the spring 5 is fixedly connected inside the workbench 1. One side of the outer wall of the sliding button 3 is fixedly connected with a first toothed plate 7. A plurality of clamping grooves 6 are provided inside the workbench 1. The outer wall of the limiting block 4 is slidably connected inside the clamping groove 6. A spur gear 8 is rotatably connected inside the workbench 1. The spur gear 8 meshes with the first toothed plate 7. A second toothed plate 9 is slidably connected inside the workbench 1. The spur gear 8 meshes with the second toothed plate 9. The top of the second toothed plate 9 is rotatably connected with a transmission rod 10. The top of the transmission rod 10 is rotatably connected with a placement rod 11. A fixing block 12 is rotatably connected inside the placement rod 11. The bottom of the fixing block 12 is fixedly connected to the top of the workbench 1. Outer shells 13 are slidably connected to both sides of the outer wall of the workbench 1. Support feet 14 are slidably connected inside the outer shells 13. A guiding component is provided inside the outer shells 13. The guiding component is used to guide the device to lift along a predetermined route;

[0025] Specifically, when using this auxiliary device for civil engineering project cost budgeting, the computer can be placed on the placement rod 11. When it is necessary to adjust the inclination of the computer, first hold down the limit block 4, and then move the sliding button 3 diagonally downward to the left. This action will activate the entire inclination adjustment mechanism. During the movement of the sliding button 3, it will drive the corresponding movement of the first toothed plate 7 connected to it. The movement of the first toothed plate 7 will further drive the rotation of the spur gear 8. The rotation of the spur gear 8 will cause the second toothed plate 9 to move diagonally upward to the right. The movement of the second toothed plate 9 will cause the placement rod 11 to rotate around the connection point between the placement rod 11 and the fixed block 12 through the rotation of the transmission rod 10. The rotation of the transmission rod 10 is achieved through its connection point with the placement rod 11. In this way, the placement rod 11 can adjust its inclination according to the rotation of the transmission rod 10. After the inclination of the placement rod 11 is adjusted to the appropriate position, the operator can release the limit block 4. At this time, the spring 5 will automatically push the limit block 4 to make it snap into the internal card slot 6, so as to keep the inclination of the placement rod 11 at the set position. This design ensures that the adjustment of the computer's inclination is both convenient and stable, enabling the user to easily adjust the inclination angle of the computer according to personal comfort and work requirements, thereby improving work efficiency and comfort.

[0026] Refer to Figure 2 - Figure 4 , the guiding assembly includes a slider 17 and a sliding column 18. The top of the sliding column 18 is fixedly connected inside the outer shell 13, and the outer wall of the sliding column 18 is slidably connected inside the slider 17. Both sides of the outer wall of the support foot 14 and the outer wall of the workbench 1 are fixedly connected to one side of the outer wall of the slider 17;

[0027] Specifically, in this auxiliary device for civil engineering project cost budgeting, the functions of the slider 17 and the sliding column 18 are to ensure that during the height adjustment of the workbench 1, the outer shell 13 and the workbench 1 can move along a predetermined route through the cooperation of the slider 17 and the sliding column 18 during their movement.

[0028] Refer to Figure 2 - Figure 4 , a first connecting rod 23 is rotatably connected inside the workbench 1, a rotating rod 22 is rotatably connected inside the outer shell 13, a second connecting rod 24 is rotatably connected inside the support foot 14. One side of the outer walls of the first connecting rod 23 and the second connecting rod 24 are rotatably connected to one side of the outer wall of the rotating rod 22. One side of the outer wall of the outer shell 13 is fixedly connected with a connection box 15. One side of the outer wall of the connection box 15 is rotatably connected with a knob 16. A transmission shaft 21 is rotatably connected inside the connection box 15. One side of the outer wall of the knob 16 is fixedly connected with a worm 19. A worm gear 20 is rotatably connected inside the connection box 15. The worm 19 is meshed with the worm gear 20. Both sides of the outer wall of the worm gear 20 are fixedly connected to one side of the outer wall of the transmission shaft 21;

[0029] Specifically, when using the auxiliary device for civil engineering project cost budget and needing to adjust the height of the workbench 1, first operate the knob 16. The knob 16 is the control component of the height adjustment mechanism and is directly connected to the worm 19. When the knob 16 is rotated, the rotational movement of the knob 16 is transmitted to the worm 19, and the worm 19 rotates accordingly. The rotation of the worm 19 meshes with the tooth surface of the worm gear 20 through its unique spiral tooth shape, causing the worm gear 20 to start rotating. The worm gear 20 is connected to the transmission shaft 21, so the transmission shaft 21 will also rotate accordingly. The rotational movement of the transmission shaft 21 is further transmitted to the rotating rod 22. When the rotating rod 22 rotates, it will drive the first connecting rod 23 and the second connecting rod 24 to rotate accordingly. The rotation of the second connecting rod 24 causes the outer shell 13 to rise along the support structure of the workbench 1, while the rotation of the first connecting rod 23 causes the workbench 1 to further rise on the basis of the already risen outer shell 13. Through this linkage mechanism, the height of the workbench 1 is adjusted. Users can adjust to a comfortable and efficient working position according to their height and sitting posture. The entire adjustment process is achieved through the coordinated work of a series of precise mechanical transmission components, ensuring the smoothness and stability of the height adjustment. After the adjustment is completed, the user can stop rotating the knob 16. At this time, due to the self-locking characteristic between the worm 19 and the worm gear 20, the height of the workbench 1 will be locked in the set position, ensuring that the adjusted height will not change due to slight external vibrations.

[0030] Working principle: When using the auxiliary device for civil engineering project cost budget, when placing the computer on the placing rod 11 and needing to adjust its inclination, first hold down the limit block 4, and then move the sliding knob 3 diagonally left and down. When the sliding knob 3 moves, it will drive the first toothed plate 7 to move. At this time, the movement of the first toothed plate 7 will drive the spur gear 8 to rotate, and the rotation of the spur gear 8 drives the second toothed plate 9 to move diagonally right and up. At this time, the movement of the second toothed plate 9 drives the transmission rod 10 to rotate around the connection point of the transmission rod 10 and the placing rod 11. When the transmission rod 10 rotates, the placing rod 11 is stressed and rotates around the connection point of the placing rod 11 and the fixed block 12 to adjust the inclination of the placing rod 11 to adjust the inclination of the computer. Subsequently, at a suitable position, release the limit block 4, and the spring 5 will push the limit block 4 into the card slot 6 to maintain this position. When needing to adjust the height of the workbench 1, the knob 16 can be rotated. Subsequently, the knob 16 drives the worm 19 to rotate, the rotation of the worm 19 drives the worm gear 20 to rotate, and then drives the rotating rod 22 to rotate through the transmission shaft 21. At this time, the rotation of the rotating rod 22 will drive the first connecting rod 23 and the second connecting rod 24 to rotate. When they rotate, the rotation of the second connecting rod 24 causes the outer shell 13 to rise, while the rotation of the first connecting rod 23 causes the workbench 1 to rise on the basis of the outer shell 13 to complete the adjustment of the height of the workbench 1.
