Folding type corner reflector capable of being folded and unfolded quickly

The utility model discloses a folding fast folding corner reflector comprising a plurality of main plates and a plurality of auxiliary plates, the edges of the main plates are sequentially and rotatably connected, the auxiliary plates are respectively and rotatably connected with the edges of two adjacent main plates, the middle parts of the auxiliary plates are provided with separated creases, the two sides of the creases are mutually and rotatably connected, and the two sides of the creases are mutually and rotatably connected. A plurality of hooks are fixedly connected to the upper end of the main plate at the top, threaded rings are fixedly connected to the edges of the main plates, and the same supporting rod penetrates through the threaded rings in a threaded mode. Compared with a traditional corner reflector, the folding corner reflector has folding performance and can be fixed according to using characteristics, so that the folding corner reflector keeps good stability, deformation caused by folding m
