[0032] The bevel gears 1 and 2 at the lower ends of the right-angle fixing member 3 and the right-angle fixing member 4 of the utility model are different in size and specification, so that the rotation speeds of the extrusion rods at their positions are different, forming a speed difference, so that the last step, the bending of the two ends of the steel bar has a sequential process.
