[0029] In this embodiment, a workbench 1 is included;

[0030] Specifically, handrails 11 are provided on the outer walls on both sides of the top of the workbench 1, and the outer parts of the handrails 11 are sleeved with rubber sleeves. The handrails 11 are used to facilitate people to move the workbench 1, and are also convenient for staff to hold tightly when explaining the bid documents, thereby relieving tension.

[0031] Specifically, drawers 12 are provided on both sides of the front of the workbench 1. The drawers 12 can store relevant information of the bid, and a slot 13 is provided on the rear side of the top of the workbench 1. The display screen 7 is arranged inside the slot 13. A top cover with the same area as the slot 13 is provided on the top of the display screen 7. After the display screen 7 is retracted, the top cover is buckled into the inside of the slot 13, which ensures the flatness of the workbench 1 and prevents dust from falling on the display screen 7.

[0032] In this embodiment, a bracket assembly 2 is fixedly installed at the bottom of the workbench 1, and the bracket assembly 2 is at least used to stably support the workbench 1;

[0033] Specifically, the bracket assembly 2 includes several columns 21 fixed on the outer wall of the bottom of the workbench 1, and reinforcement rods 22 are fixed between adjacent columns 21. The top of the reinforcement rod 22 is provided with a support rod 23 located at the bottom of the storage box 3, and the bottom end of the column 21 is provided with a universal wheel 24. The universal wheel 24 used has a brake structure to ensure the stability of the workbench 1.

[0034] In this embodiment, a storage box 3 is provided below the workbench 1 and located inside the bracket assembly 2. The storage box 3 is used to store at least the bid-related materials.

[0035] In this embodiment, an extension component 4 is provided on the back side of the storage box 3. The extension component 4 can be extended to both sides of the workbench 1. The extension component 4 is at least used for people to sit on.

[0036] Specifically, the extension assembly 4 includes a storage box 41 arranged between the storage container 6 and the storage box 3. Telescopic rods 42 are slidably inserted at both ends of the storage box 41. The telescopic rods 42 can be extended from both ends of the storage box 41. The ends of the telescopic rods 42 are provided with sleeves 43, and the internal threads of the sleeves 43 are inserted with screw rods 1 44. The top of the screw rods 1 44 is installed with a seat plate 45, and the bottom of the screw rods 1 44 is provided with legs 46. After the telescopic rods 42 are extended, the seat plate 45 is driven to move from the bottom of the workbench 1 to the side of the workbench 1. Then the staff rotates the seat plate 45, so that the screw rods 1 44 rotate inside the sleeves 43, so that the legs 46 contact the ground, allowing the staff to sit on the seat plate 45.

[0037] Specifically, the end of the telescopic rod 42 is a bent structure, and the bending curvature of the telescopic rod 42 is the same as the curvature of the reserved position at the corner of the storage box 3. After the seat plate 45 is retracted, the seat plate 45 can be hidden and placed under the workbench 1, so that the device can save more storage space after being folded and stored.

[0038] In this embodiment, a storage container 6 is provided at the lower back side of the workbench 1. The storage container 6 is a hollow cavity structure, which plays a role in protecting the display screen 7. The display screen 7 is provided inside the storage container 6. The display screen 7 is used for electronic display of the tender documents at least.

[0039] In this embodiment, a lifting mechanism 5 is provided inside the container 6, and the lifting mechanism 5 is used at least to lift the display screen 7 inside the container 6 and the workbench 1;

[0040] Specifically, the lifting mechanism 5 includes a screw rod 2 52 and a guide rod 54 arranged on both sides of the interior of the storage container 6. The bottom end of the screw rod 2 52 is provided with a driving motor 51 fixed to the bracket assembly 2. The external thread of the screw rod 2 52 is sleeved with a screw nut 53. A base is provided at the bottom of the display screen 7. One end of the base is fixedly connected to the screw nut 53, and the other end of the base is slidably sleeved on the guide rod 54. Starting the driving motor 51 can drive the screw rod 2 52 to rotate. Under the cooperation of the screw rod 2 52 and the screw nut 53, the base of the display screen 7 moves linearly up and down inside the workbench 1 and the storage container 6, thereby achieving the effect of lifting and lowering the display screen 7 and realizing the extension and retraction of the display screen 7.

[0041] Working principle: (1) When using the device, the staff can classify and store the relevant materials prepared for the bidding in the storage box 3 and the drawer 12;

[0042] (2) Then, the staff can extend the seat plate 45 through the extension component 4, allowing the staff to sit on the seat plate 45 to wait or listen to the tender document explanation of their colleagues;

[0043] (3) When the staff member is explaining the tender documents, he or she activates the lifting mechanism 5 to make the display screen 7 rise from the inside of the workbench 1 and the container 6, so that the auditor or peer can see the content on the display screen 7;

[0044] (4) After explaining the contents of the tender document, the staff folded up the device and took away their own information for future use.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
