The invention discloses a mechanical type adjustable manually-operated perforating machine. The mechanical type adjustable manually-operated perforating machine comprises a base, an adjustment device,a sliding block, a compression shaft, a spring and a compression rod. The adjustment device is arranged at one side of the upper end of the base and comprises fixing blocks, a lead screw and a drivenblock, wherein the fixing blocks are symmetrically arranged, the lead screw is rotatably connected between the fixing blocks, and the driven block is arranged on the lead screw. A fixing support plate is vertically arranged at the upper end of the driven block. Two sliding grooves are vertically formed in the front side of the fixing support plate. The rear side of the sliding block is connectedinto the two sliding grooves through two sliding strips. A connecting block is arranged at the front side of the sliding block. The compression shaft is vertically connected to the front side of the connecting block through a compression block. Springs are symmetrically connected to the two sides of the sliding block through self-tapping screws. A tool grove is transversely formed in the position,corresponding to the position under the compression shaft, on the base. Magnet strips are arranged at the two sides of the tool groove correspondingly. The mechanical type adjustable manually-operated perforating machine is simple in structure and convenient to use; tool bits of different specifications can be replaced rapidly; the perforating machine can be precisely transversely adjusted; the distances among holes are controlled and adjusted; and the mechanical type adjustable manually-operated perforating machine is applicable to precise perforating.
