[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides an embodiment of a special calculation device for engineering cost, comprising a housing 1, a protective groove 5 on the top of the housing 1, a rotating block 2 fixedly mounted on one side of the inner side of the protective groove 5, a calculator 4 rotatably connected to one side of the rotating block 2, a latch on the top of one side of the inner side of the protective groove 5, the calculator 4 can be pulled out from the latch, making it easy to unfold the calculator 4, three sets of locking blocks 3 are provided on one side of the top of the calculator 4, a locking rod 7 is mounted on one side of the bottom of the inner side of the protective groove 5, and a fixing component is provided in the middle of one side of the housing 1.

[0027] A storage groove 9 is provided at the bottom of one end of the outer casing 1. A material plate 8 is slidably fitted inside the storage groove 9. Guide grooves are provided on both sides of the inner side of the storage groove 9. Guide blocks that cooperate with the guide grooves are provided on both sides of the material plate 8, which can restrict the movement direction of the material plate 8, so that the material plate 8 can slide along the groove under the guidance of the guide blocks. A sliding groove 16 is provided in the middle of one end of the outer casing 1. A slider 15 is slidably connected inside the sliding groove 16. A baffle 14 is provided on one side of the slider 15. A spring B17 is provided on the top of the slider 15. A pressure block is provided at the bottom of one end of the baffle 14, which can press and fix the material on the material plate 8.

[0028] Furthermore, the fixing assembly includes a wedge-shaped insert 10, a sleeve 11, a spring A12, and a slot 13. A sleeve 11 is provided in the middle of one side of the outer casing 1. The wedge-shaped insert 10 is sleeved on the inner side of the sleeve 11, and the spring A12 is sleeved on the outer side of the wedge-shaped insert 10. A slot 13 that mates with the wedge-shaped insert 10 is provided on one side of the calculator 4 to fix the calculator 4.

[0029] Furthermore, a groove 6 is provided at the bottom of the inner side of the protective groove 5 to cooperate with the locking rod 7. When the calculator 4 is put away, the locking rod 7 can be stored in the groove 6 to reduce the space occupied.

[0030] Working principle: When using this device, the wedge-shaped plug 10 can be pulled out of the slot 13 to overcome the elastic force of the spring A12. Then the calculator 4 can be flipped out of the protective groove 5 and rotated so that the display screen faces upward. Then, the locking rod 7 can be inserted into the locking block 3 to adjust to a suitable angle for use. After the device is used, the calculator 4 can be flipped into the protective groove 5 so that the display screen faces downward. After the calculator 4 is inserted into the protective groove 5, the wedge-shaped plug 10 can be automatically inserted into the slot 13 to fix the calculator 4.

[0031] When using calculator 4, the baffle 14 can be pulled up under the guidance of slide 16 to overcome the upward movement of spring B17 and release the blockage of storage slot 9. Then the material board 8 can be pulled out from storage slot 9. The project cost document can be placed on the material board 8, and then the baffle 14 can be reset by the elastic force of spring B17. At this time, the document can be fixed by the pressure block, which makes it convenient for staff to calculate the project cost.
