The present invention includes a close contact wing portion and a main body fixing portion, wherein the close contact wing portion and the main body fixing portion are fixedly connected to each other, and the close contact wing portion is used to support the fracture end portion and is adapted to the inner surface of the diaphysis. The structure has a structure in which the main body fixing portion is used to fix the close contact wing portion and is adapted to the front side surface of the diaphysis, and the first locking is performed at the boundary between the main body fixing portion and the close contact wing portion. At least two first locking holes through which the screw passes are provided, and at least two second locking holes for allowing the second locking screw to pass through are provided in the structure that matches the anterior surface of the diaphysis. The present invention relates to a wing type angle steel plate. The wing-type angle steel plate according to the present invention supports the stable reduction and fusion of the fracture site by fixing and supporting the fracture end portion of the diaphysis in cooperation with the close contact wing portion and the body fixing portion connected to each other.
