The glass fiber reinforced thermosetting resin composite material is a non-metallic material, so that the tower profile prepared from the glass fiber reinforced thermosetting resin composite material has certain limitation on a connecting structure, and cannot be welded and connected like steel. Therefore, the joint connecting device of the glass fiber reinforced thermosetting resin composite material tower becomes a great problem restricting the development of the glass fiber reinforced thermosetting resin composite material tower and is also a problem which needs to be solved in the development of the industry.
