Abstract

The present invention relates to the field of punches, in particular to a paper-binding punch. The paper-binding punch is composed of a bottom plate (1), a pressure plate (2), a lifting and dropping switch (3), a punching switch (4), a storage battery (5), a charger (6), a lower limit switch (7), an upper limit switch (8), channels (9), punching electric motors (10), a lifting and dropping electric motor (11), gears (12), racks (13), drill bit clips (14), drill bits (15) and vertical rods (16). The paper-binding punch, which is a punch dedicated to papers, is characterized by simple structure and convenient operation. The paper-binding punch resolves the trouble that the punching of a large quantity of paper devices spends much and labor, and moreover, punched holes are in order, thus ensuring the binding appearance and order.

Description

technical field [0001] The invention belongs to the field of punching devices, in particular to a punching device for binding examination papers. Background technique [0002] After the examinee takes an exam, the binding of examination papers is an important and cumbersome task. Usually, the invigilator manually drills holes in the stacked examination papers with a drill, then binds them with a needle and thread through the rows of holes, and then seals them with a seal. The binding of examination papers is not only highly demanding, and no unevenness is allowed, but also cannot damage the examination papers. These tasks will cost the invigilators more energy and time. There are several kinds of binding devices on the market: one is a punching machine for loose-leaf books, and its shortcoming is that the hole diameter is large and cannot be used; the second is a punching machine for pressing three nails by hand, and its punching Quantity is limited, can not press more than...
