摘要： PROBLEM TO BE SOLVED: To provide the novel punch for office work on which improvement is made to dissolve inconveniences encountered when used. SOLUTION: A fixed side plate 1 is connected to a movable side plate 2 in such a way as to be freely opened/closed by way of a free folding part located at the rear side periphery of the stationary side plate, and cutting edge holes 16 and 17 and cutting edge bodies 23 and 24 are provided for the plate 1 and the movable side plate 2 respectively. Furthermore, engaging projections 10 and 11 and engaging holes 12 and 13 are provided for places close to the rear sides at both right and left sides of the plate 1 and the movable side plate 2 in such a way that the tip ends of the engaging projections 10 and 11 are fitted in the engaging holes 12 and 13 after the engaging projections have been brought into contact with the engaging holes. Besides, in the movable side plate 2, a part located over a horizontal line crossing a space between each mounting place for the cutting edge bodies 23 and 24 and each set-up place for the engaging projections 10 and 11, is made thin, so that the aforesaid part can thereby be deflected.

摘要： PROBLEM TO BE SOLVED: To provide the novel punch for office work, on which improvement is made to eliminate structural defects. SOLUTION: A movable side plate 2 is connected with a fixed side plate 1 in such a way as to be freely opened/closed at the rear side periphery of the stationary side plate, cutting edge holes 16 and 17 are provided for the side plate 1, and fixedly attaching pins 18 and 19 are also provided for the movable side plate 2 at places corresponding to the aforesaid cutting edge holes 16 and 17. Separately from the aforesaid items, cutting edge bodies 23 and 24 are formed out of rigid synthetic resinous material where four cutting edges in a substantial triangular pyramid shape each are projected in a state that these cutting edges are in a continuous condition while being located in the four directions, and also in a state that one side surface of each triangular cone is formed into the extended surface of the outer circumferential surface of a cylindrical body, in the tip end surface of the cylindrical body of an outer circumferential diameter fairly smaller than the diameter of each cutting edge hole 16 and 17. The inner diameter holes of the cutting edge bodies 23 and 24 are fitted to the fixedly attaching pins 18 and 19, and the cutting edge bodies 23 and 24 are fixed onto the movable side plate 2 by crushing and widening the tip ends of the fixedly attaching pins 18, 19 with these tip ends heated up.
