[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the billboard provided by the present application can change the direction of the display board when encountering typhoon weather, so that the display direction of the billboard is tangent to the wind direction, thereby greatly reducing the force-bearing area of ​​the billboard and better coping with strong wind weather. When the wind continues to strengthen, the display board generates a large amount of torque when encountering strong wind weather, and the torque is applied to the corresponding card block. When the torque is large enough, the card block falls off from the card slot, and the support rod rotates in the sleeve, thereby reducing the area of ​​the display board that bears the wind force. When the wind continues to increase, the support rod continues to rotate, so that the block is opposite to the slide slot. Under the action of gravity, the support rod slides inside the support rod, thereby lowering the height of the billboard and reducing the risk of the billboard falling.
