Problems solved by technology

[0003] This kind of publicity board has at least the following problems. When publicizing outdoors, if there is a strong wind, this kind of publicity board is easy to be blown down, or even hurt people

Due to the need for the promotional frame to be stable at the required position, usually the lower end of this kind of publicity board is a tripod, and when it needs to be moved again, the whole body needs to be lifted to move, which greatly increases the burden on the user

In addition, the height of the traditional publicity board is the same as that of ordinary people. When watching the publicity, the people in the rear part will not be able to see it clearly due to the body of the front viewer, and the benefit area is narrow.

At the same time, considering the difference in the height of the publicity and pasting personnel, the fixed publicity board cannot be adjusted in real time, which brings inconvenience to the user

Even though there are liftable publicity boards on the market at this stage, the human mechanics of the viewers are ignored. The increased height of the publicity board is convenient for the viewers in the back row to review at the same time. It is more laborious, so a new type of mobile publicity board device that can adjust the angle of the publicity board according to the height has become an inevitable trend in the development of today's industry.
