[0032] Specifically, the inner side of the corresponding side plate 20 is provided with a sliding guide rail 2033, and the side plate 20 is provided with a deviation correction movable notch 2300 at a position close to the sliding guide rail 2033; the second end of the deviation correction roller unit 203 is sleeved with a deviation correction guide roller 2032, which is rollingly connected to the sliding guide rail 2033; the reciprocating deviation correction driving structure 23 is arranged on the outer side of the side plate 20, the second end of the deviation correction roller unit 203 is movably arranged through the deviation correction movable notch 2300, and is connected to the reciprocating deviation correction driving structure 23.

By arranging multiple laser head units in an inclined direction to form a laser breakdown structure, the leather fabric passing in a straight line can ensure the hole density, uniform distribution and high hole quality during high-temperature arc hole processing.
