Problems solved by technology

[0004] The object of the present invention is to provide a propaganda stand, by setting a clamping mechanism, the clamping mechanism includes several "L" shaped corner clips and several elastic ropes, and the elastic ropes fix the "L" shaped corner clips on the publicity frame Inside, the "L"-shaped corner clamping block clamps and fixes the four corners of the poster, so as to adapt to the fixed posting of posters of different sizes; at the same time, a dust removal mechanism is set up. The scraper moves up and down, which solves the problem that the existing propaganda device has a complex fixed structure to adapt to posters of different sizes, is driven by power, and is inconvenient to connect to electricity; at the same time, there is a lack of dust removal device in rural areas, and the problem of losing the propaganda effect after being covered with dust
