The invention relates to the technical field of official business handling equipment and discloses an accounting document hole drilling
machine. During drilling by the accounting document hole drilling
machine, firstly a compressing sleeve is used for compressing a hole drilling portion, then hole drilling is performed, the problem that tearing and the like occur to an accounting document at the position of the hole drilling portion can be effectively solved, and the problem of deformation and the like at the hole drilling position is solved. Meanwhile, the accounting document hole drilling
machine is further provided with an outer protecting
barrel, and on one hand, a drilling cutter can be protected, and it is prevented that mistaken injuries are caused to operators; and on the other hand, during drilling, a lifting driving
barrel moves up and down while driving the drilling cutter to rotate, and automatic hole drilling is achieved; besides, when the accounting document hole drillingmachine performs drilling, paper scraps are sucked out due to negative pressure, and the situation that a
drill bit is stuck by the paper scraps and consequently the accounting document is damaged bythe
drill bit is prevented; and the drilling cutter is of a cylindrical thin-wall structure, the paper scraps are directly sucked out from the center according to the
cut-out shape, and operation iseasy and convenient.
