These one-hole punch tools have punch guides or the like only in one direction, and may be difficult to use for those who do not match their dominant hand.
An object of the present invention is to provide a one-hole punching tool in which the punch guide can be used on either the right or left side of the punching tool.

  The one-hole punching tool of the present invention has an operating part fixing part fixed to the upper part of a base having a punch waste reservoir on the lower surface, and a handle is mounted on the front part of the operating part fixing part so as to be rotatable by a fulcrum pin. Then, when the handle is pushed down, the punching blade installed inside lowers and punches the document inserted from the insertion slot. It is anchored to a punch guide pin fixed to the lower surface of the reservoir. The punch guide has a long and narrow punch guide sliding hole in the center. The lower surface of the punch waste reservoir stores the punch guide and pulls out the punch guide. There is a punch guide storage cover for the purpose of restricting the punch guide to be perpendicular to the base when it is rotated. While holding the punch guide pin, the base moves only in the long side direction until the punch guide is pulled out from the punch guide storage cover to the maximum, and when the punch guide is pulled out to the maximum, the left and right directions are up to 90 degrees. Rotation and movement perpendicular to the long side direction of the base when rotated 90 degrees left or right, or movement only in the long side direction of the base when in the same direction as the long side direction of the base are possible There is a plate spring between the punch guide and the lower surface of the punch waste reservoir, and the punch guide is pressed by the punch guide press so that it does not move carelessly.

  The user of this one-hole punching tool can use the punch guide on the side that is easy to use, and convenience is increased.

It is a perspective view at the time of the punch guide accommodation of the Example of the 1-hole punch tool of this invention. It is a perspective view from the downward direction of the Example of the 1-hole punch tool of this invention. It is sectional drawing of the Example of the 1-hole punch tool of this invention. It is sectional drawing at the time of handle pressing of the Example of the 1-hole punch tool of this invention. It is a top view from the lower side at the time of the punch guide accommodation of the Example of the 1-hole punch tool of this invention. It is a top view from the lower side at the time of pulling out the punch guide of the Example of the 1-hole punch tool of this invention. It is a top view from the lower side at the time of punch guide rotation of the Example of the 1-hole punch tool of this invention. It is a top view from the lower side at the time of the punch guide set of the Example of the 1-hole punch tool of this invention. It is a figure which shows a punch guide incorporating order. It is a figure in the middle of punch guide incorporation.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

It is assumed that a hole having a size through which the punch guide presser 9a can pass is provided at the center of the leaf spring 15.
The punch guide pin insertion portion 5a has a size that allows the punch guide retainer 9a to pass therethrough.
The width of the punch guide sliding hole 5b is smaller than the diameter of the punch guide retainer 9a.
In FIG. 10, the long side direction of the base 2 and the long side direction of the punch guide 5 are perpendicular to each other. From this state, the punch guide is passed through the punch guide retainer 9a to the central hole of the leaf spring 15 and the punch guide pin insertion portion 5a. When 5 is pressed, the state shown in FIG.
When the punch guide 5 is moved in the long side direction from the state shown in FIG. 11 while the punch guide 5 is being pressed, the width of the punch guide sliding hole 5b is smaller than the diameter of the punch guide press 9a. Moored at.

  The width of the punch guide sliding hole 5b is set to such a size that it can be slid by being anchored to the punch guide pin 9.

  The end of the punch guide 5 far from the punch guide pin insertion portion 5a is a quarter of a circle whose radius is one half of the length of the square diagonal line with the width of the punch guide 5 as one side. One arc.

  A mark corresponding to the format of the document for setting the punch guide 5 at a predetermined position is provided on the upper surface of the punch guide 5.
