Abstract

PROBLEM TO BE SOLVED: To enable to use cleanly without scattering of chad after punching, by fitting, rotatably, two punching levers perforating across the inside of a paper insertion space which opens upward, has a concave sectional, and lets paper to be punched vertically down, to a base through toggle links. SOLUTION: Punching levers 5 perforating across the inside of a paper insertion space 3 which is formed with a concave sectional and opens upward at the tip of a base 1 are combined by slender coupling pieces 9. Toggle links 12 connected by pins 10 are fitted to coupling pieces 9 at the tip 2a of an operating handle 2 which is rotatably fitted to the base 1 by a pivot 7, and the operating handle 2 is rotated up and down, then cutting edges of the hollow punching levers 5 press and cut the paper let down into the paper insertion space 3, and they press themselves strongly against a strike plate 13 in the final process. Thus, a slip of paper can be prevented from moving, by providing paper end receptors 20, 21 at each outside end of two rack pieces 18, 19, and operating one of the rack pieces.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-hole manual punch having two perforated rods (commonly referred to as "kines").

[0002]

BACKGROUND OF THE INVENTION A hollow two-hole manual punch equipped with two piercing rods at required intervals has been provided so that all of the piercing rods are vertically lowered and raised up to now. It is designed to punch down several layers of paper by pressing down from above, and to return to ascending after perforation. Since the punch having this structure pierces the paper by the pressing-down motion, the piercing operation is performed without any trouble, and no inconvenience occurs. However, after punching out, it is removed, but it adheres to the hollow perforated rod and scatters around the perforated rod away from the perforated rod when the perforated rod returns to the ascending position.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a two-hole punch which can be used cleanly without being scattered around the hole after drilling and which has a good feeling after drilling, especially by a toggle mechanism. Is to do.

[0004]

The means of the present invention are as follows.

[0005] A paper insertion gap is provided in the container base for opening the upper surface, forming a concave cross section, and vertically dropping paper to be pierced.
A compact two-hole manual punch in which two perforating rods penetrating across the paper insertion gap are connected to an operation handle pivotally connected to a base via a toggle link so as to be able to advance and retreat.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a hollow base, and 2 denotes an operation handle.

The base 1 has a paper insertion gap 3 having a concave cross section with an open upper surface at the tip end, and has two perforated rods 4 and 5 penetrating across the inside of the paper insertion gap 3. The operation handle 2 is pivotally attached to the table 1 by a pivot 7 so that the two perforated rods 4 and 5 are integrated by an elongated connecting piece 9 and connected to the tip 2a of the operation handle 2 by a pin 10. When the toggle links 11 and 12 are attached to the connecting piece 9 and the operation handle 2 is turned up and down, the paper pieces dropped into the paper insertion gap 3 by the cutting edges of the hollow perforated rods 4 and 5 are pushed off, and the final In the stroke, the cutting edge is strongly pressed against the receiving plate 13. This action has a toggle-specific effect, with a very clear feel at the end of the cut, without the ambiguity of a conventional punch. In the figure, reference numeral 15 denotes a return coil spring having one end hooked on the connecting piece 9 and the other end hooked on the stop piece 16 in the base 1.
Is a pinion attached to the receiving stand 13, and a paper end receiver 2 at the outer end of each of the upper and lower two rack pieces 18 and 19 meshing with the pinion.
If one of the rack pieces is operated with 0 and 21 provided, both rack pieces 18 and 19 are opened and closed to prevent the paper piece from moving. Reference numeral 25 denotes a receiving bin.

[0008]

As described above, the two-hole punch according to the present invention completely revises the conventional concept, performs the piercing operation by turning the piercing rod sideways and reciprocating the horizontal movement of the piercing rod. All of them are stored in the bin 20 which is neatly arranged, and the performance as a punch is significantly improved in tandem with the adoption of the above-mentioned toggle mechanism.
