う問題があつた。 Conventionally, in order to drill a large amount of thick materials such as paper, cloth, leather, or synthetic resin boards, a shaft is rotated by an electric motor and a drill connected to the tip of the shaft is used to drill the hole. Puncturing things. However, as shown in the upper half of Figure 1,
Drilling debris c pushed out from the discharge hole b of shaft a as shown by arrow A is piled up in the center of the debris receiving box d as shown in the figure, that is, in the area above shaft a. c... presses the upper part e of the waste receiving box d as shown by arrow B, and the reaction force acts on the waste c... in the discharge hole b of the shaft a and on the waste clogged near the tip of the drill. There was a problem that the drill hole was easily clogged with debris, and cleaning the debris was troublesome. Further, due to the action of the pressing force in the direction of arrow B, the waste receiving box d fitted on the upper surface of the casing f is pushed up and separated,
There was a problem that the stored waste c... spilled outside.

To provide an electric punch that does not blow out small pieces of waste, has little power loss, and has low noise. Therefore, the features of the present invention are that a flat waste receiving box is removably placed on the upper surface of the casing, and a shaft with a discharge hole extending in the axial direction is attached to the upper end of the drill. and the upper end of the shaft corresponds to the hole formed in the center of the bottom of the scrap receiving box,
Further, a scum blowing member is attached to the upper end of the shaft, and the scum blowing member includes a short cylindrical main body and a horizontally or horizontally twisted shape protruding from the outer periphery of the upper end of the main body. The protruding length of the blade is set to be sufficiently smaller than the outer diameter of the main body, and the upper half of the scum blowing member is inserted into the hole of the scum receiving box. At the same time, the gap between the hole and the main body of the scrap-repelling member is set small, and the blade is inserted into the hole so that the rotation locus of the blade covers the gap from above. The blade is located close to the upper edge of the opening of the waste receiving box, and furthermore, the blade is formed to be elastically deformable by an elastic member so that the blade can pass through the hole of the waste receiving box.

所定部位に孔が開設される。 Next, to explain the operation of the present invention, first, the mounting height position of the adjusting rod 32 is adjusted by tightening/loosening the knob 33 in accordance with the height position of the tip of the drill 9 fitted to the lower end of the shaft 12. is determined, and the movement range of the drill 9 in the directions of arrows G and H is set. Then, the pressing fixture 35 is lifted upward against the elastic force of the resilient member, and the edge of the object 16 to be drilled is clamped and fixed, and is slidable on the front edge and left and right edges of the base 1. The positioning adjustment tools 36 attached to the holes are respectively slid in the longitudinal direction to position the object 16 to be drilled according to the size of the object 16 to be drilled, and to hold the object 16 so that it does not move during the drilling operation. Next, switch 40
Shaft 1 that rotates when turned ON
2, the drill 9 is rotated. and,
If the manual lever 3 is swung around the support shaft 4 as shown by the arrow E, it will operate on the principle of a lever with the support shaft 4 as the fulcrum.
The casing 5 slides on the support shaft 2 via the swinging arm 8 against the elastic force of the elastic member as shown by arrow D. As a result, the drill 9 moves as indicated by the arrow G while rotating, so that a hole is drilled at a predetermined portion of the object 16 placed on the base 1.

である。 The present invention has effectively achieved the intended purpose with the configuration detailed above. In particular, a scum blowing member 18 having elastically deformable blades 25 is attached to the upper end of the shaft 12, and the perforated scum 17 is pushed out from the discharge hole 13 by the rotational drive of the shaft 12.
Since the structure is configured so that the perforated debris 17 is scattered to the periphery of the debris receiving box 26, the perforated debris 17 is deposited in an ant-hell shape as shown in FIG. The storage capacity of the waste receiving box 26 is increased and the perforated waste 17 can be efficiently stored without accumulating on the surface. In addition, as described above, since the drilling debris 17 does not accumulate in the upper part of the shaft 12, the drilling debris 17 does not press against the upper part 42 of the debris receiving box 26 as in the conventional case, and therefore the reaction force is transferred to the upper stage where it is connected. Hole 2
0. Since it does not act on the drilling debris 17 clogged in the discharge hole 13 and the guide hole 10, debris clogging phenomenon is unlikely to occur, cleaning the debris is easy, and easy and quick drilling operation is possible, and the debris receiving box 26 The state of fitting onto the upper surface 27 of the casing 5 is ensured. Furthermore, since the blades 25 are made of an elastic member that can be elastically deformed, when the waste receiving box 26 is attached or detached, the blades 25 come into contact with the tapered surface and the upper end of the hole 29 and the fourth
It is elastically deformed as shown by the imaginary line in the figure, making the attachment/detachment operation smooth. In addition, since the blades 25 are provided to protrude in the radial direction at positions close to the upper part of the hole 29, the blades 25...
9, and the main body part 24 and the hole part 2
9 from the gap formed between the upper end of the hole 17
It also serves to prevent ... from spilling outward. In this way, it is a device that has great practical effects.

小であり、騒音も発生しない。 In particular, when compared with the conventional example described in JP-A-55-101399, the following effects are obtained. In other words, the perforated waste 17 can be stored in an ant-like hell inside the waste receiving box 26 in the most effective manner without requiring a separate waste basket. Since the vanes 25 use centrifugal force to blow away the perforation debris 17, they do not blow out air and therefore do not scatter small debris fragments. The rotational torque acting on the blades 25 is minute and no noise is generated.

Regardless of whether the blades 25 are projected into the waste receiving box 26 from the hole 29, the blades 25 are elastically deformed and pass through the hole 29, making it possible to easily attach and detach the waste receiving box 26.
