[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model connects the device to an external power supply through a line and starts it through an external controller. When the staff needs to fix the engineering cost drawing, the two ends of the limit rod three are placed on the top of the two limit support blocks in advance, and then the positive and negative motor two is started through the external controller. The rotation of the positive and negative motor two drives the connecting shaft connected to it to rotate, and the rotation of the connecting shaft drives the gear connected to it to rotate. The rotation of the gear drives the two tooth plates connected to it to translate, and two T-slots are embedded in two limit bars to support and limit the two tooth plates. The translation of the two tooth plates drives the translation of the two hollow connecting frames connected to them, and the two limit rods two are used to limit the two hollow connecting frames until the bottom of the two hollow connecting frames are aligned with the engineering cost drawing. When both sides of the paper are aligned, the forward and reverse motors 2 are stopped, and then the limit rod 3 is taken out from the top of the two limit support blocks.

After pressing, the limit rod 3 is entered from the top of the through slot 3, and then slides inward after entering the through slot 3 to complete the locking of the two fixed plates. If the engineering cost drawings need to be unlocked, only the limit rod 3 needs to be operated in the reverse direction to unlock it from the through slot 3, and then it needs to be replaced on the top of the two limit support blocks. In this way, when fixing the engineering cost drawings, only the limit rod 3 needs to be taken and pressed down. The fixing and unlocking methods are relatively simple and suitable for engineering cost drawings of different sizes.

[0014] 2. According to the utility model, when the staff needs to display the engineering cost drawings, the positive and negative motor 1 is started through the external controller, and the output end of the positive and negative motor 1 rotates to drive the threaded rod connected thereto to rotate, and the threaded rod rotates to drive the connecting block and the clamping block connected thereto to move up, and the clamping block moves up to drive the display board connected thereto to move up, and at the same time, a limit rod 1 is set on the connecting block on the other side to limit. When the display board moves up, since the two sides of the bottom of one end are respectively connected by two clamping plates, the two clamping plates follow the display board to move up and drive the two extension arms to deflect until the two extension arms deflect to the limit, so as to keep one end of the display board stationary in place, and at the same time, since the clamping blocks on both sides of the display board continue to rise, the display board itself gradually tilts until it is close to vertical. When the display is completed and the drawings need to be stored, the positive and negative motor 1 can be reversed to make the display board return to a horizontal state. In this way, the display board that is initially horizontal can be changed to a vertical state, which is convenient for the staff to view the drawings, and it is also convenient for the staff to place and fix the drawings when the display board is horizontal.

[0038] Working principle: the device is connected to an external power supply through a line and started by an external controller. When the staff needs to fix the engineering cost drawings, the two ends of the limit rod 3 5 are placed on the top of the two limit support blocks 105 in advance, and then the forward and reverse motor 2 401 is started by the external controller. The forward and reverse motor 2 401 rotates to drive the connecting shaft 402 connected thereto to rotate, and the connecting shaft 402 rotates to drive the gear 403 connected thereto to rotate, and the gear 403 rotates to drive the two tooth plates 404 connected thereto to translate, and two T-slots 405 are embedded in the two limit bars 301 to support and limit the two tooth plates 404, and the two tooth plates 404 translate to drive two hollow connecting frames 406 connected thereto The two limit rods 303 are used to limit the two hollow connecting frames 406 until the bottoms of the two hollow connecting frames 406 are aligned with the two sides of the engineering cost drawing, and the forward and reverse motors 401 are stopped. Then the limit rods 35 are taken out from the tops of the two limit support blocks 105.

After compression, the limit rods 35 are inserted from the top of the through slots 3 409, and after entering the through slots 3 409, they slide inward to complete the locking of the two fixed plates 410. If you want to unlock the engineering cost drawing, you only need to reversely operate the limit rods 35 to unlock it from the inside of the through slots 3 409. , and re-place it on the top of the two limit support blocks 105. In this way, when fixing the engineering cost drawings, it is only necessary to take the limit rod 3 5 and press it down. The fixing and unlocking methods are relatively simple and suitable for engineering cost drawings of different sizes. When the staff needs to display the engineering cost drawings, the forward and reverse motor 1 2 is started by the external controller, and the output end of the forward and reverse motor 1 2 rotates to drive the threaded rod 201 connected thereto to rotate. The threaded rod 201 rotates to drive the connecting block 203 and the clamping block 204 connected thereto to move up. The clamping block 204 moves up to drive the display board 3 connected thereto to move up, and at the same time, the connecting block 203 on the other side is provided with a limit rod 1 202 to limit the position. When the display board 3 moves upward, since the two sides of the bottom of one end are connected by two clamping plates 208 respectively, the two clamping plates 208 move upward with the display board 3 to drive the two extension arms 207 to deflect until the two extension arms 207 deflect to the limit, so as to keep one end of the display board 3 still in place. At the same time, since the clamping blocks 204 on both sides of the display board 3 continue to rise, the display board 3 itself gradually tilts until it is close to vertical. When the display is completed and the drawings need to be stored, the forward and reverse motor 2 can be reversed to make the display board 3 return to a horizontal state. In this way, the display board 3, which is initially horizontal, can be changed to a vertical state, which is convenient for the staff to view the drawings. When the display board 3 is horizontal, it is also convenient for the staff to place and fix the drawings.
