Description

Description: TECHNICAL FIELD The present invention relates to a multi-hole punch that can be used as a one-hole punch or a two-hole punch as required.

(Prior Art) In a multi-hole punch in which three or more holes are punched simultaneously, each cutting edge must have a large punching force. This is because the larger the number of cutting blades, the greater the force required unless each cutting blade is cut. In this respect, the shaft-shaped cutting blade that has been often used in the past has a large number of cutting chips, or when the thick perforated paper is perforated, the chips generated by the perforation clogging the cutting edge of the cutting blade, and the effective part Since it was possible to perforate only a fixed number of sheets of paper or a sheet of fixed thickness by increasing the number of cutting blades, when the number of cutting blades was increased to form a multi-hole punch, it was practically unusable. Further, in Japanese Utility Model Application Publication No. 13068 of 1948, a platform provided with a punching rod so as to cross a U-shaped recess into which a paper to be punched is inserted, and a horizontal rod having a bent portion formed at an end thereof. It is possible to adjust the pitch interval between the bases by inserting a plurality of holes into the base and insert a horizontal rod for raising and lowering the punching rod, and a plurality of punching rods are attached by the grips attached to the horizontal rod. There is disclosed a hole punching device for simultaneously raising and lowering.

Further, in Japanese Utility Model Publication No. 28-8307, a groove is formed on a base for fitting a block body provided with a perforating rod so as to cross a thin-film insertion groove for inserting a paper to be punched. The block body is inserted into the block body, the horizontal rod is applied to the rear part of the block body, and the horizontal rod is pressed with the bolts to fix the block body to the base so that the pitch interval between the block bodies can be adjusted. ing.

The vertical movement of the drilling rod is attached to the operating rod that is rotatably provided on the base with a pressing rod that abuts against the heads of the drilling rods of a plurality of blocks, and by pushing down the operating rod, a plurality of drilling rods are pushed down. It is disclosed that a rod is pressed down at the same time so as to make a hole in a paper.

(Problems to be Solved by the Invention) In any of the above-mentioned conventional bases and blocks, since the horizontal rod and the operating lever for pushing down the punching rod and the drilling rod are provided separately from the base and the block, Further, when the block and the block are removed from the base, there is no means for pushing down the punching rod and the punching rod, so that the base and the block cannot be used as a single punching machine. Therefore, there is a problem that it does not function as a one-hole punch.

In addition, in the one disclosed in Utility Model Application Publication No. 13068 in 1948, the horizontal rod inserted into the table has a bent portion, so the table can be removed from this horizontal rod. No
Further, in the one disclosed in Japanese Utility Model Publication No. 28-8307, the rear portion of the block is fixed by pressing it with a horizontal rod, so when adjusting the pitch between the blocks, the horizontal pressure is applied to the horizontal rod. There is a problem that it is troublesome to fasten a plurality of bolts to loosen the bolts and loosen the fastening.

(Means for Solving Problems) As a means for solving the above problems, the present invention provides a single hole having a cylindrical cutting blade that is lifted and lowered by a lever and a blade receiving plate that receives the cutting edge of the cutting blade. A plurality of punches are provided on the base plate, a plate body for simultaneously pressing a plurality of levers of the one-hole punch is provided, and a screw hole is provided on the front surface of the plate body of the one-hole punch and a long hole is provided on the front surface of the substrate. Is provided, and the bolt is inserted into the long hole of the substrate and screwed into the screw hole of the plate body of the one-hole punch.

(Operation) Since the present invention is configured in this way, it has the following operations. That is, since the one-hole punch here is capable of moving the cylindrical cutting blade up and down by the lever and making a hole between it and the blade receiving plate that receives the cutting edge of the cutting blade, the one-hole punch itself. It becomes possible to construct a single one-hole punch that can punch a paper by pushing the lever to move the cutting blade up and down.

Then, a screw hole is provided on the front surface of the plate body of the one-hole punch provided on the board, and a long hole is provided on the front surface of the board, and a bolt is inserted into the long hole of the board to screw it into the screw hole of the plate body. Since they are fitted together, the one-hole punches can be easily attached and detached, and the pitch intervals between the one-hole punches can be easily adjusted.

Further, since the levers of the plurality of one-hole punches are pressed by the single plate body, by pressing the plate body, it becomes possible to simultaneously lower the plurality of cutting blades via the levers.

(Embodiment) Next, one embodiment of the present invention will be described with reference to the drawings. First, FIGS. 1 and 2 show a completed assembled state, and FIG. 3 shows an exploded state thereof. Further, FIG. 4 shows a part of the cross section, and FIG. 5 shows a perspective view. In these figures, 1 is a one-hole punch which will be described later, and 2

The elongated holes 26 of 23 are engaged from below. Bending part
A screw hole 27 is provided in 24, and a long hole 28 is provided in the pressing / bending portion 25 at a position matching the screw hole 27 in the lateral direction. Then, a knob bolt 29 is inserted from the outside of the long hole 28 through the spring washer 30 and the washer 31 and screwed into the screw hole 27. In the case of the three-hole punch, since the central one-hole punch does not need to be moved, the bolt 29a used here may not be manually turned. 32 is a scale for determining the perforation position of the perforated paper. Small holes 33 are provided side by side in the substrate 23 so that the plate 18 can be seen from above. Then, the substrate 23 and a part of the plate 18 are painted differently, for example, black and red. This makes it possible to change the position of the plate 18 with respect to the substrate 23, in other words, the pitch between the holes punched by the one-hole punches 1,1. After assembling in this way, the plate member 34 is placed on the lever 2 from above and fixed with the screw 35. 36 is a decorative plate. It should be noted that this fixing is performed only for the central one-hole punch, and not for both-side single-hole punches. In the figure,
37 is a stopper arm that regulates the angle of the lever 2 when the multi-hole punch is stored, 38 is a hole through which the stopper arm 37 passes, and 39 is a shaft that serves as a fulcrum of the stopper arm 37.

In this multi-hole punch constructed in this manner, the perforated paper is inserted from above the substrate 23, the tip thereof is pressed against the standing portion of the base 4, and the plate 34 is pressed down. As a result, the cutting blade 3 perforates and penetrates the paper to be perforated, and contacts the blade receiving plate 21. At this time, the blade receiving plate 21 is slightly damaged as described above, but is not damaged. When there are many scratches, the blade receiving plate 21 is rotated by a slight angle to change the place.
