Specifically, the winding layer 5 is made of a sheet-shaped composite material with a certain width and a certain thickness, and the winding layer 5 is wound on the outer surface of the filling layer 4 to form a plurality of circumferential layers. The winding mode adopts the existing multiple winding modes, for example, each annular layer can be parallel to the horizontal plane, namely, the annular layer is vertical to the longitudinal direction of the original rod, and can also form an angle of plus or minus 45 degrees with the horizontal plane, namely, each annular layer forms an angle of plus or minus 45 degrees with the horizontal plane, or the spiral winding can be carried out.
