Problems solved by technology

[0003] 1. If the wind is too strong at the outdoor exhibition site, it will cause the knife flag to fall, which will bring inconvenience to the exhibition;

[0004] 2. There is a collar or bag on the side of the knife flag, but when arranging the display site, because the diameter of the collar or bag is generally only slightly larger than the pole, the collar or bag is worn on the pole The online process is time-consuming and laborious, seriously affecting work efficiency;

[0005] 3. When the display site is relatively hard and flat ground such as cement or marble, it is necessary to insert the knife flag pole on the base. The base is a hollow plastic device. When using it, pour water into it to support the knife flag pole. Generally, there are two holes, the drain outlet at the bottom of the base and the water inlet at the top of the base, but when filling water, it is easy to cause the gas in the cavity to not come out and the water not to flow down, which also causes time-consuming and labor-intensive work. Seriously affect work efficiency;

[0006] 4. The collar or bag on the top of the knife flag is designed as an opening. When the wind is strong at the display site, it is easy to cause the knife flag to curl, so that the knife flag is wrapped around the entire pole and loses the meaning of display
