The correction cover 81 can be connected to the correction cover bracket 83 through an elastic device 84, thereby realizing the floating connection of the correction cover 81 to avoid damaging the parts to be corrected (T iron and magnet). The inner diameter of the correction cover 81 is slightly larger than the outer diameter of the raised mounting portion on the T-iron, so that when the correction cover 81 is covered on the raised mounting portion on the T-iron, the T-iron can be concentric with the inner hole 811 of the correction cover 81. A conical surface 812 is provided on the outside of the correction cover 81. When the correction cover 81 is covered on the T-iron, the conical surface 812 abuts against the inner wall of the center hole of the magnet, thereby adjusting the magnet to be concentric with the T-iron, thereby realizing the correction of the T-iron and the magnet.
