PROBLEM TO BE SOLVED: To provide a one-hole punching tool comprising a punch guide guiding a punch position for an initial hole and a punch position for a second hole in which the punch guide may be used in two directions.SOLUTION: A punch guide guiding a punch position with punch guide press is pinned by a punch guide pin fixed on a lower surface of a punch dust receptacle. While the punch guide holds the punch guide pin on a punch guide slide hole, the punch guide may be moved in the following movements: until the punch guide is maximally drawn from a punch guide storing cover, movement only in a longer side direction of a base table; when the punch guide is maximally drawn, rotation in both left and right directions by 90 degrees; when being rotated in a left or right direction at 90 degrees, rectangular movement to the longer side direction of the base table; or when being in the same direction with the longer side direction of the base table, movement in only the longer side direction of the base table. The punch guide comprises a marker for punching an initial hole at a predetermined position on a paper and a marker for adjusting an initially punched hole for punching a second hole with a predetermined interval from the initial hole.SELECTED DRAWING: Figure 1 |
