[0008] As an improvement, a non-slip soft pad that matches the tender document is adhered to the pressure pad, which can increase the friction between the pressure pad and the tender document.

[0009] As an improvement, a pulling plate is fixedly connected to the long board, and the pulling plate is provided with anti-slip grooves to facilitate pulling the long board.

[0010] As an improvement, a display screen is provided on the vertical board, and an interface board cooperating with the display screen is provided on one side of the vertical board, so that multimedia comments can be used.

[0011] As an improvement, the interface board is provided with a USB-A port, a Type-C port and an HDMI port.

[0012] As an improvement, a whiteboard and a containing box are provided on the vertical board, and the containing box is convenient for containing whiteboard pens.

[0013] (III) Beneficial effects

[0014] The advantage of the utility model over the prior art is that the reviewers can use the clamping mechanism to clamp the tops of different tender documents in the grooves, so that the different tender documents can be hung on the lower ends of the cross bars. This makes it convenient to display and compare the participants in the discussion during the review process, and can facilitate the review of the tender documents. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3The construction project management bidding device includes a base plate, a vertical pole 2 and a vertical plate 3 are fixedly connected to the upper end of the base plate 1, a display screen 5 is arranged on the vertical plate 3, and an interface board 8 cooperating with the display screen 5 is arranged on one side of the vertical plate 3, and multimedia review can be used, and the interface board 8 is provided with a USB-A port, a Type-C port and an HDMI port, a whiteboard 6 and a containing box 7 are provided on the vertical plate 3, and the containing box 7 is convenient for containing whiteboard 6 pens, and at least one cross bar 4 is fixedly connected between the vertical pole 2 and the vertical plate 3 and is evenly arranged in sequence from top to bottom, and at least one groove 9 is evenly arranged in the cross bar 4, and a clamping mechanism cooperating with the tender document is provided in the groove 9.

[0022] Combined with Figure 1 , Attachment Figure 2 and attached Figure 4 The clamping mechanism includes a spring 12 which is arranged relatively to the inner wall of the groove 9, a long plate 10 is provided at one end of the spring 12, a pressure pad 13 which cooperates with the tender document is provided on the long plate 10, a non-slip soft pad which cooperates with the tender document is adhered to the pressure pad 13, which can increase the friction between the pressure pad 13 and the tender document, a pull plate 11 is fixedly connected to the long plate 10, and the pull plate 11 is provided with anti-slip grooves to facilitate pulling the long plate 10.

[0023] During the specific implementation of the utility model, when in use, the commentator extends the top of the paper document of the tender that needs to be compared into the groove, and pulls the pull plate at the same time. At this time, the spring is in a stretched state. When the top of the paper document of the tender is extended into the groove, the pull plate is released, and the long plate moves toward the direction of the paper document of the tender under the pulling force of the spring until the pressure pad is close to the paper document of the tender. In this way, the paper folder of the tender can be tightly held in the groove, and the purpose of hanging the paper document of the tender on the cross bar can be achieved. This makes it convenient for the commentator to show and compare the paper documents of the tender to the discussants. When multimedia is needed for commenting, the multimedia video can be played on the display screen using the interface in the interface board, and a whiteboard pen can be used to write on the whiteboard.
