ーを提供することを目的とする。In this case, the present invention allows even an unskilled person to easily cut the corrugated steel pipe of a metal-clad cable to a desired length to expose the conductor, thereby quickly and reliably cutting the waveform. To provide a cutter for a corrugated coated steel pipe in a metal sheathed cable, which can cut the type coated steel pipe, has a simple structure, and can perform the work safely.
以下本考案を図面と共に説明すれば、1は波型被覆鋼管
のカッタ一本体であり、切開の際に支点となる支点腕2
と保持部3とより成る。The present invention will be explained below with reference to the drawings. 1 is a cutter body made of corrugated coated steel pipe, and a fulcrum arm 2 serves as a fulcrum during incision.
and a holding part 3.
支点腕2の先端には、波型被覆鋼管の頂部の外面形状に
ほぼ一致する形状の凹所4が形成されている。A recess 4 is formed at the tip of the fulcrum arm 2 and has a shape that approximately matches the outer surface shape of the top of the corrugated coated steel pipe.
保持部3の底部には軸方向に溝5が形成され、保持部3
の側面にはボルト挿通孔6が形成されている。A groove 5 is formed in the axial direction at the bottom of the holding part 3.
A bolt insertion hole 6 is formed in the side surface.
切開刃7は刃部8と取付部9から戊り、刃部8の先端に
は切開の際の保合ストッパ一部8aが設けられ、取付部
9には取付孔9aが形成されている。The incision blade 7 is separated from the blade part 8 and the attachment part 9, and the distal end of the blade part 8 is provided with a retaining stopper part 8a for incision, and the attachment part 9 is formed with an attachment hole 9a.
切開刃7はカッタ一本体1に対してその刃部8を該支点
腕2に向けると共にこれと略平行状態において、孔6,
9aを介してボルト10とナツト10 aにより固着さ
れる。The incision blade 7 faces the cutter body 1 with its blade 8 facing the fulcrum arm 2 and in a state substantially parallel to the fulcrum arm 2.
It is fixed by a bolt 10 and a nut 10a via a bolt 9a.
ボルト挿通孔6は長孔に形成されているので、切開刃7
の取付装置を変更して支点腕2の凹所4と刃部8間の距
離を調整でき、金属がい装ケーブルのサイズに合せて最
適な切開状態に出来る。Since the bolt insertion hole 6 is formed into a long hole, the cutting blade 7
The distance between the recess 4 of the fulcrum arm 2 and the blade part 8 can be adjusted by changing the attachment device of the fulcrum arm 2, and the optimum cutting state can be achieved according to the size of the metal-insulated cable.
なお、11は保持部3に被せたグリップ、12は波型被
覆鋼管13とケーブル14とで構成される金属がい装ケ
ーブルである。Note that 11 is a grip placed on the holding portion 3, and 12 is a metal-inserted cable composed of a corrugated coated steel pipe 13 and a cable 14.
次に切開手順について説明すれば、先づ金属がい装ケー
ブルのケーブル端部を所望長さに残す個所の波型被覆鋼
管13の頂部に糸鋸等により切開刃7の入る穴を開口し
、波型被覆鋼管の頂部に支点腕2の凹所4を載せながら
切開刃7を該開口に挿入する。Next, to explain the cutting procedure, first, a hole into which the cutting blade 7 is inserted is made using a jig saw or the like at the top of the corrugated coated steel pipe 13 where the cable end of the metal-insulated cable is left at the desired length. The cutting blade 7 is inserted into the opening while placing the recess 4 of the fulcrum arm 2 on the top of the coated steel pipe.
この状態で保持部3を上方に持ち上げることにより、刃
部8により波型被覆鋼管13を常に上方へ広がる様に切
開して行く。By lifting the holding part 3 upward in this state, the blade part 8 cuts the corrugated coated steel pipe 13 in such a way that it always spreads upward.
この際に保合ストッパ一部8aは切開中に切開刃7が波
型被覆鋼管外に抜は出るのを阻止して、円滑な切開作業
に役立つ。At this time, the retaining stopper portion 8a prevents the cutting blade 7 from coming out of the corrugated coated steel pipe during cutting, thereby contributing to smooth cutting work.
所望長さに切開した後は、切開開始個所を金切り鋏み等
で切り落し、必要ならばやすり等で面取りする。After making the incision to the desired length, cut off the starting point of the incision using scissors or the like, and if necessary, chamfer it with a file or the like.

る。Since the present invention is constructed as described above, the cutting operation can be performed with a relatively weak force using the lever principle, and the recess of the support arm is aligned with the cutting blade along the top of the corrugated coated steel pipe. The incision marks are formed in a relatively orderly manner, and the top of the corrugated steel pipe is always incised in such a way that it spreads upwards, making it easy to process the ends. Since a portion of the retaining stopper is provided, the retaining stopper partially locks onto the terminal edge of the cut portion of the corrugated coated steel pipe during the cutting operation, preventing the blade from coming off outward. It has the features of being easy to continue working, easy to use even by unskilled people, and enabling quick and reliable cutting work.
