Abstract

The invention relates to a paper perforating device, in particular to a paper perforating device for an accounting teaching and aims at solving the technical problems to provide the paper perforating device for the accounting teaching with small amount of labor, high working efficiency and no liability in damaging paper. For solving the technical problems, the invention provides the paper perforating device for the accounting teaching. The paper perforating device for the accounting teaching comprises a bottom plate, an electric wire winding wheel, a first stay wire, a pressure plate, a wood collection frame, a guide wheel, a left bracket, guide plates, an oscillating rod, a top plate, a first slide rail, a mobile frame, a first sliding block, pressure rods, a first spring, a wedge-shaped block, a contact rolling wheel, a stop dog, a lifting rod, a perforating drill, a sliding sleeve, a mobile rod, a connecting frame and the like; and the top of the bottom plate is sequentially provided with the left bracket from left to right. According to the paper perforating device for the accounting teaching, the effects of small amount of labor, high working efficiency and no liability in damaging paper are reached; and as the perforating drill can carry out rapid perforation on the paper, the perforating time can be reduced, the working efficiency can be improved, and the treating time can be increased.
