[0011] Further, the limiting screw penetrates the threaded through hole, and the end thereof contacts the upper surface of the guide rail; the flat surface of the thimble is clamped between the fixed block and the stop seat.

[0012] The utility model has the following beneficial effects: the whole set of jig needs to be fixed on the wire cutting equipment operation platform in advance through the base, and after the XY direction coordinates are calibrated to be horizontal, the wire cutting is taken as a reference. The flat thimble is directly installed between the stop block and the fixing mechanism for wire cutting, and the XY horizontal position of the flat thimble does not need to be calibrated again. The wire cutting process becomes simpler and more convenient to operate, not only improves the machining efficiency of the workpiece, saves the machining time, but also improves the operation rate of the machine, and saves the labor cost.
