[0007] As a preferred implementation, one end of the bidirectional screw is fixedly connected to a handle.

[0008] As a preferred embodiment, a fixing rod is fixedly installed between the two brackets, a first limiting groove is formed on the top of the fixing rod, and the first sliding block is slidably connected in the first limiting groove.

[0009] As a preferred implementation, a second limiting groove is formed at the bottom of the display board, and the second sliding block is slidably connected in the second limiting groove.

[0010] As a preferred implementation, a third limiting groove is provided on the inner side of the bracket, and third sliders are fixedly connected to both sides of the display board, and the third sliders are slidably connected in the third limiting groove.

[0011] As a preferred embodiment, a roller is provided at the bottom of the bracket.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The cultural and creative exhibition board for exhibition construction is provided with a bidirectional screw, a first slider, a second slider and a connecting rod. When in use, only the handle needs to be turned to make the handle drive the bidirectional screw to rotate, so that the bidirectional screw drives the first slider to slide, so that the first slider drives the connecting rod to rotate through the second slider, so that the connecting rod drives the display board to be raised or lowered, thereby facilitating the adjustment of the height of the display board, reducing the difficulty of operation and making it more convenient to use.

[0014] The cultural and creative exhibition board for exhibition construction limits the first slider through the first limiting groove, limits the second slider through the second limiting groove, and limits the display board through the third limiting groove, so as to improve the stability of the display board.
