Description

Technical Field

[0001] The invention relates to the technical field of flagpoles, and in particular to a rotatable flagpole with a function of preventing flags from being entangled. Background Art

[0002] From ancient times to the present, flags have always been a symbol of the cohesion and centripetal force of the masses. In today's era, peace has become the theme of the development of the times. The flag-raising and flag-lowering ceremonies have become an indispensable part of crowd activities, 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. But 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; when the flag is raised, lowered or at a certain height, due to the constant change of natural wind direction, the flag often appears to be entangled on the flagpole and cannot be stretched and fluttered. In the case of no wind or light wind, the flag cannot be stretched and fluttered well. If this kind of situation occurs during major events, it is quite regrettable. Most people feel the same way and hope for changes.

[0003] The flag on the flagpole is easily tangled around the outside of the flagpole when blown by the wind. When it is raised, the flag often becomes tangled and cannot be fully extended, which prevents the flag-raising ceremony from proceeding smoothly and reduces the quality of the flag-raising ceremony. Summary of the invention
