[0027] Embodiment 1:

[0028] See also Figure 1-5 The utility model provides a construction engineering cost analysis device, comprising:

[0029] Workbench 1 and support frame 2;

[0030] A plurality of universal wheels 3 are arranged at the bottom end of the support frame 2. A rectangular groove is provided through the workbench 1. Two fixing plates 4 are provided in the rectangular groove. An adjusting plate 5 is provided on one side of the rectangular groove.

[0031] The threaded rod 6 is penetrated and arranged on the two fixing plates 4. The external threads on both sides of the threaded rod 6 are arranged in opposite directions. Both sides of the rectangular groove are slidably connected with matching bearing plates 7. The ends of the two bearing plates 7 are extended to the outside and are provided with limit plates 8.

[0032] The positioning plate 9 is rotatably connected to one side of the upper end of the workbench 1 , a positioning groove is provided on one side of the positioning plate 9 , and a plurality of clamping plates 10 are provided on one side of the positioning groove.

[0033] Specifically, Figure 2 As shown, thread grooves matching the threaded rod 6 are provided on opposite sides of the two supporting plates 7. The two ends of the threaded rod 6 are respectively located in the two thread grooves and are threadedly connected to the side walls of the thread grooves. By rotating the threaded rod 6, the supporting plates 7 on both sides can be driven to move in relative directions.

[0034] Specifically, Figure 2 , Figure 3 and Figure 4 As shown, a driving shaft 11 is rotatably connected to the bottom end of the rectangular groove, a first bevel gear 12 is provided on the outside of the threaded rod 6, and a second bevel gear 13 meshing with the first bevel gear 12 is provided on the upper end of the driving shaft 11. The driving shaft 11 can drive the threaded rod 6 to rotate through the first bevel gear 12 and the second bevel gear 13.

[0035] Specifically, Figure 3 and Figure 4 As shown, a servo motor 14 is provided at the bottom of the workbench 1. The servo motor 14 is prior art and will not be described in detail here. The bottom end of the driving shaft 11 passes through the rectangular groove and is arranged on the output end of the servo motor 14. The output end of the servo motor 14 will drive the driving shaft 11 to rotate.

[0036] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both ends of the adjustment plate 5 are rotatably connected with connecting rods 15, and the other ends of the two connecting rods 15 are rotatably connected to one side of the two supporting plates 7 respectively. The upper end of the adjustment plate 5 is rotatably connected with an adjusting rod 16, and the upper end of the adjusting rod 16 passes through the rectangular groove and is rotatably connected to one side of the positioning plate 9.

[0037] Through its design, when the two carrying plates 7 move, the adjusting plate 5 can be driven to move through the two connecting rods 15. When the adjusting plate 5 moves, the positioning plate 9 can be driven to rotate through the adjusting rod 16.

[0039] See also Figure 1-5 When using the construction project cost analysis device, it is first necessary to drive the servo motor 14. The output end of the servo motor 14 will drive the driving shaft 11 to rotate. The driving shaft 11 will drive the first bevel gear 12 and the threaded rod 6 to rotate through the second bevel gear 13 at the end. The rotation of the threaded rod 6 will drive the bearing plates 7 on both sides to move relative to each other, thereby increasing the storage capacity of the construction project cost analysis device. When the two bearing plates 7 move, the adjustment plates 5 can be driven to move through the two connecting rods 15 respectively. The adjustment plates 5 will drive the positioning plates 9 to rotate through the adjusting rods 16. Then the required drawings or materials can be fixed on the positioning plates 9 through multiple clamping plates 10, so that the construction project cost analysis device is more practical.
