Problems solved by technology

Not only that, because there is no effective means to adjust the positional relationship between the previous perforation position and the subsequent perforation position, so it is difficult to perforate all the holes in the proper position.

Embodiment Construction

[0039] Embodiments of the present invention will be described below with reference to the drawings. Figure 1, figure 2 As shown, the perforator P in the present invention has a main body 1 , an operating rod 2 rotatably supported on the main body, and a perforating knife 3 that advances and retreats with the rotation of the operating rod 2 . The joystick 2 is installed on the upper part of the main body 1 by means of a rotating shaft 21 . The perforating knife 3 is supported on the root of the joystick 2, that is, near the rotating shaft 21, and advances and retreats in the up and down direction as the joystick 2 is rotated, and pierces through the sheet body from above. The illustrated example is a so-called 2-hole perforator, and two perforating knives 3 are respectively arranged at the root of the joystick 2 . The main body 1 includes a base 11 that has a substantially square shape in plan view and supports the joystick 2 via a rotation shaft 21 , and a cover 12 attached ...

Abstract

The present invention is to provide a piercer P with improved convenience. In the piercer P composed of a main body 1, an operating rod 2 rotatably supported on the main body 1, and a piercing knife 3 that advances and retreats with the rotation of the operating rod 2, the main body 1 is provided on the above-mentioned main body 1 for piercing with another. These piercers P can be connected by engaging the connection portion 13 of one piercer P with the connection portion 13 of the other piercer P.

Description

technical field [0001] The present invention relates to a perforator for perforating paper and other sheets. Background technique [0002] As tools for perforating a sheet, for example, those listed in the following patent documents are known. These are so-called 2-hole perforators, which punch 2 holes along the perimeter 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, the number of holes that the perforator can perforate on the sheet at one time is the same as the number of perforating knives that the perforator has. However, sometimes you want to drill more holes than the number of piercing knives. If more holes than the number of perforating knives are to be perforated, multiple perforating operations have to be performed. For example, when it is desired to perforate four holes in a sheet body and there is only a 2-hole puncher at hand, the 2-hole...
