The invention relates to a punching positioning device. The punching positioning device comprises a plurality of positioning rulers, wherein the positioning rulers are straight rulers; a first slot isformed in each positioning ruler; the slot length direction of each first slot is consistent with the length direction of the corresponding positioning ruler; a first movable positioner for fixing amarking pen is arranged on each first slot; one ends of all the positioning rulers are connected together through a fixer; and the number of the positioning rulers is 2-5. When the punching positioning device is used, the plurality of positioning rulers are sequentially stacked together, and the fixer fixes all the positioning rulers together. The fixer plays a reference role, after the marking pens are placed in the first movable positioners and/or second movable positioners, the marking pens can be used for marking the positions at certain length distances from the fixer for calibration, andthe plurality of positioning rulers can be used at the same time to mark the punching positions as required. The punching positioning device is flexible in structure and capable of accurately positioning punching holes at different positions.
