[0029] Further comprising a driving device 500 for controlling the relative movement of the first polishing assembly 2001 and the second polishing assembly 2002, and the relative staggered movement of the two cross rods 600 is controlled by the driving device 500; the initial state of the two cross rods 600 is shown in the figure Figure 1 perpendicular to each other, the first end of the first cross rod 600 abuts against the first end of the second cross rod 600, and the driving device 500 can control the transverse movement of the first cross rod 600 while moving longitudinally until the second end of the first cross rod 600 abuts against the second end of the second cross rod 600, and the two cross rods 600 rotate while moving relative to each other, completing the continuous rust removal and polishing of the surfaces of the two cross rods 600.
