[0027] In use, when the shoe material needs to be drilled, the first adjusting part 21 and the second adjusting part 31 need to be rotated respectively according to the required drilling diameter, and the corresponding punch 32 and the limiting hole 22 are used. The punch 32 and the limiting hole 22 are in a position corresponding relationship in the above state, and at this time, the shoe material is placed on the opening of the upper end of the cavity 20 of the operation table 2, that is, above the limiting hole 22. At this time, the first driving source 3 (hydraulic cylinder) drives the assembly set 30, the second adjusting part 31 and the punch 32 to move downward to drill the shoe material;
