In today's era, peace has become the theme of the development of the times. From countries and departments at all levels to primary and secondary schools or various large-scale sports events, flag-raising and flag-lowering ceremonies have become indispensable activities for the crowd, and the flagpole is an indispensable carrier for the flag to fly. Under normal circumstances, raising and lowering the flag or keeping the flag at a certain height can basically be completed. However, we have seen that the flag often cannot be stretched and fluttered due to the lack of natural wind and other meteorological conditions, especially in the middle and lower parts of the flagpole, where the flag is rarely stretched and fluttered.
