るため、極めてわずらわしかつた。 For example, in Utility Model Publication No. 45-2073, a cutting/perforating machine is used to cut asbestos/cement boards used for wall boards or roof boards into desired sizes, to drill nail holes, etc., and to cut corners. What is described is publicly known. In the conventional cutting/perforating machine, an upper frame and a lower frame, both of which have cutting blades on their opposing surfaces, are pivotally connected at their rear ends, and the front end of the upper frame is connected to the lower end of the front end of the handle, and the lower frame is connected to the lower frame at the lower end of the front end of the handle. The front end was pivoted to the handle at the upper end of the front end of the handle through a vertical guide plate, and a U-shaped front punch attachment was attached to the pivot portion of the handle. Therefore, when inserting the plate to be drilled into the groove of the punch attachment to make a hole, a hole is provided in advance from the front part of the attachment (the side opposite to the handle) depending on the distance from the edge of the plate to be drilled to the drilling position. The depth of the groove was adjusted by inserting and removing a pin into the hole, which was extremely troublesome.

として下方に押圧され、切断作用が付与される。 In FIG. 1, a cutting/perforating machine A has a lower holder 8 having a lower blade 1 that is straight in the front-rear direction (horizontal direction in the figure), and an upper blade 2 having a gently curved convex central part. The holder 5 is connected to the upper and lower blades 2,
The structure is such that the plate material sandwiched between the two blades is cut by pressing the blades 1 into a so-called pressed-cut shape.
That is, the lever handle 3 and the lower holder 8 are pivotally supported by the vertical guide plate 9 via the upper and lower pins 4 and 7, and the handle 3 can be pushed down as shown by arrow P around the pin 4. As a result, the handle protrusion 3a presses the protrusion receiver 5a, and the upper holder 5 is pressed downward around the pivot pin 6 at the rear (right side in the figure) of the cutting/perforating machine A, thereby imparting a cutting action.

る。 On the other hand, when drilling a hole in a plate material, a U-shaped attachment 10 facing away from the handle (toward the front on the left side in FIG. 1) is fixed to the handle pivot, and the U-shaped attachment 10 is inserted into the U-shaped groove 13 of the attachment. The punch rod 15 is made to protrude horizontally while holding B. The base body 11 of the U-shaped attachment 10 is fixed to the vertical guide plate 9 by bolts 18, and its upper part is penetrated by the upper pin 4. Further, the substrate 11 of the attachment 10 has a support portion 12 having a groove 13 with an upward opening.
are simultaneously fixed by the bolts 18. A punch rod hole 14 facing in the front-rear direction is provided in the upper part of the base body 11, and the hole 14 has a small inner diameter section 14b at the front and a large inner diameter section 14a at the rear via a step 14c. A punch rod 15 is inserted into the punch rod hole 14 and has a small outer diameter portion 15b and a large outer diameter portion 15a that are horizontally slidable on the inner diameter portions 14b and 14a. A gap is provided between the stepped portion 14c of the punch rod hole and the front end of the large outer diameter portion 15a of the punch rod, and a coil spring 16 is installed in the gap to move the punch rod 15 toward the free end of the handle in an unloaded state. The bullet bounces back. The punch rod 15 can be advanced into the groove 13 by being pushed by a pressing protrusion 31 provided near the pivot portion by pressing the handle 3 in the direction of the arrow P, and the punch rod 15 is pushed into the groove 13 by pressing the handle 3 in the direction of the arrow P. 12b has the small outer diameter portion 15b of the punch rod.
An escape hole 17 is provided which allows entry of the operator.
A groove step portion 13a capable of supporting the perforated plate B is provided on the inner surface of the groove 13 of the support body 12 on the handle pivot side.

１６の弾撥力により元の位置に復帰する。 When drilling a hole in a plate to be drilled B using the above-described drilling attachment 10, the plate to be drilled is inserted into the groove 13 and the handle 3 is pressed in the direction of arrow P.
By this action, the pressing protrusion 31 provided at the base of the handle presses the rear end of the punch rod 15, and the tip of the punch rod traverses the U-groove 13 and makes a hole. At this time, when the plate to be perforated is inserted all the way to the bottom of the groove 13 as shown by B1 , the edge of the plate
l Correctly drilled in position 1 . In addition, the plate to be perforated
When placed on the groove step 13a indicated by B 2 , a hole is formed at a position l 2 from the edge. After drilling is completed, when the handle 3 is lifted, the punch rod 15 returns to its original position due to the elastic force of the spring 16.
