Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the piercing device P of the present embodiment has two piercers p, and the piercers p, such as figure 2 As shown, there are a main body 1, a handle 2 rotatably supported on the main body 1, and a piercing blade 3 indicated by dotted lines that advances and retreats with the rotation of the handle 2 . The handle 2 is mounted on the upper part of the body 1 via a rotating shaft 4 . The piercing blade 3 is supported at the base of the handle 2, that is, near the rotating shaft 4, moves up and down as the handle 2 is rotated, and pierces through the sheet from above. The illustrated example is a so-called double-hole piercer, and two piercing blades 3 are respectively arranged at the root of the handle 2 . The main body 1 includes a base 11 that is substantially square in plan view and supports the handle 2 via a rotating shaft 4 , and a cover 12 attach...

Abstract

A punching device P includes the plurality of punches p each having a main body 1, a lever 2 rotatably supported by the main body 1, punch blades 3 moving backward and forward along with turning of the lever, and a gauge groove 13 supporting a gauge G which positions the sheet. The punching device P is provided with a connector 20 for connecting the plurality of punches p by using the gauge grooves 13.

Description

technical field [0001] The present invention relates to a perforating device and a connecting member for perforating sheets and other papers. Background technique [0002] As tools for punching a sheet, for example, those listed in the following patent documents are known. These are so-called double hole punchers, which are instruments that punch 2 holes along the edge of the sheet. [0003] Patent Document 1: JP-A-2002-331496 [0004] Patent Document 2: JP-A-2002-001699 [0005] Patent Document 3: JP-A-2002-001698 [0006] Generally speaking, the number of holes that can be punched in a sheet by the puncher at one time is the same as the number of punching blades that the puncher has. However, it may be necessary to drill more holes than the number of piercing blades. In order to drill more holes than the number of piercing blades, it is necessary to perform a plurality of piercing operations. For example, if you want to punch four holes in a sheet but only have a dou...
