Description

Technical field [0001] This patent relates to a device that can lift various slogan banners from the ground to a high altitude to achieve the purpose of hanging. Background technique [0002] At present, the suspension of banners generally adopts the following two methods: [0003] 1.

The disadvantage of this method is that people have to go up to a high place, the installation efficiency is low, and because the upper and lower edges of the banner are slightly longer than the middle, it is not easy to stretch. [0004] 2. For banners that are frequently changed, there are also some methods to avoid high-altitude operations, that is, to install a pulley at the height that needs ...

AI Technical Summary

Problems solved by technology
