後、パンチシヤフト２をねじ込んでいくことによ
り鉄板に穿孔するように構成されている。 As a conventional tool of this type, there is one shown in FIG. 1, for example. This tool screws a punch shaft 2 on one rising part of a U-shaped main body 1, and a die 3 on the other rising part of the main body 1.
After the iron plate 4 is applied to the die 3, the punch shaft 2 is screwed in to punch a hole in the iron plate.
しかしながら、このようなあなあけ工具にあつ
ては、パンチシヤフトをねじ込むとにより穿孔す
るようになつているため、穿孔作業に時間がかか
り、また、円形のあなしか穿設することができな
いという欠点があつた。 However, such hole-drilling tools have the drawback that the hole is drilled more when the punch shaft is screwed in, so the hole-drilling process takes time, and it can only drill circular holes. Ta.
本考案の目的は、このような欠点を解消し、非
円形の透孔でも素早く穿設することができるあな
あけ工具を提供するにある。 An object of the present invention is to provide a drilling tool that can overcome these drawbacks and quickly drill even non-circular holes.
この目的を達成するため、本考案は一対のレバ

ている。 FIG. 2 shows an embodiment of the present invention,
The main body 11 of this drilling tool is formed in a substantially U-shape, and a guide hole 12 is bored at a substantially right angle in the substantially central portion of one rising portion of the main body 11. A shaft 13 is slidably inserted into the guide hole 12, and a punch 14 is formed at the tip of the shaft 13. Guide hole 1 of main body 11
One end of a pair of levers 15, 15 is rotatably attached to both sides of the lever 1, respectively.
One end of each link bar 16, 16 is pivotally attached to the intermediate portion of each link bar 5, 15, respectively. The free ends of both link bars 16, 16 are connected to the shaft 1.
3 is rotatably connected by a pin 17 at the rear end. A die 18 is formed on the other raised portion of the main body 11 so as to directly face the punch 14.
次に作用を説明する。 Next, the action will be explained.

握るという極めて簡単な動作で、容易かつ素早く
穿孔することができる。 As shown in FIG. 2, when the iron plate 4 is applied to the punch side of the die 18 of the main body 11 and the levers 15, 15 are squeezed to retract and close the shaft 13, the shaft 13 is moved along the guide hole 12 by the action of the link bar 16. Tsute die 1
8, the iron plate 4 is pushed into the die 18 to punch out a through hole. At this time, the forward force of the shaft 13 is amplified by the lever action of the lever 15 and the link bar 16, and especially when both link bars become parallel, the forward force corresponding to the push-out force becomes almost constant. With the extremely simple action of squeezing the lever, you can easily and quickly drill holes in iron plates.
このように、シヤフト１３の前進力で鉄板をダ

とにより、円形は勿論、角形、長円形等所望に応
じた任意形状の透孔を穿つことができる。 In this way, holes are made by pushing the steel plate toward the die using the forward force of the shaft 13, so by appropriately selecting the cross-sectional shapes of the punch and die, it is possible to form holes into any desired shape, such as circular, rectangular, or oval. A hole of any shape can be made according to the requirements.
なお、前記実施例では、パンチ１４をシヤフト
１３に、また、ダイ１８を本体１１にそれぞれ一

孔を穿つことができて便利である。 In the above embodiment, the punch 14 is integrally formed with the shaft 13, and the die 18 is integrally formed with the main body 11. However, if the punch and the die are configured to be replaceable, it is possible to form through holes in a plurality of different shapes. It is convenient to wear.

できる。 As explained above, according to the present invention, since the shaft is moved forward by the action of the lever and the link to push out the object to be drilled, such as an iron plate,
It is possible to make holes in any circular or non-circular shape, and it can be done with an extremely simple action of squeezing a lever.
