[0003] During building construction, it is necessary to set up a construction warning frame to remind people on the outer edge of the construction site, so as to inform people of the construction here and pay attention to safety. site, and if the amount of construction work is large, it is necessary to place various types of warning frames, which makes the replacement frequency of the warning frames higher. Therefore, the simplicity of operation is an important development requirement for the warning frames; In each position, the all-round display of the warning frame is also an important improvement direction
