に保つ役割を有している。 Reference numeral 11 denotes a cylindrical body, and the head of the cylindrical body has an insertion opening 12 through which a cut object 13 such as a string can pass, as shown in the figure. A cutting knife 14 has a blade 15 at its tip. The angle of the cutting edge is 30~60°
It is. The cutting knife 14 includes, for example, a shear pin 16 that communicates with the cylindrical wall and the knife.
As a result, the cutting edge is held relative to the cylindrical body 11 so as to maintain an accurate cutting position relative to the object to be cut. Reference numeral 17 denotes a gas generator, which is fixed by suitable means, for example, by screwing into the rear part of the cylindrical body. The inside of the gas generator is filled with a gas generating agent.
The gas generator is connected to the ignition device by a conductor 18. Reference numeral 19 is an O-ring, which has the role of keeping the gap between the inner wall of the cylinder and the knife airtight even when the cutting knife slides.
〈考案が解決しようとする問題点〉
前述の従来の切断具により被切断体を切断する

させる。発生したガスの圧力が切断用ナイフに加
わり、ナイフは筒体内を急進し、その刃先１５が
被切断体を筒体頭部内壁に押しつけ切断する。<Problems to be Solved by the Invention> A method for cutting an object to be cut using the above-mentioned conventional cutting tool will be described below. Attach the object to be cut, for example, the string 13, to the insertion hole 12 as shown in FIGS. 3 and 4,
The ignition device ignites the gas generating agent to generate gas. The pressure of the generated gas is applied to the cutting knife, and the knife rapidly advances inside the cylinder, and its cutting edge 15 presses the object to be cut against the inner wall of the head of the cylinder and cuts it.
この場合次に示す問題点がある。 In this case, there are the following problems.
まず刃先は切断に最も適した角度、即ち30〜
60°とする必要がある。又切断用ナイフは被切断

断用ナイフが常に正しい位置を保持するように調
節せねばならない。 First, the blade edge should be set at the most suitable angle for cutting, i.e. 30~
It needs to be 60°. Furthermore, the cutting knife must move its cutting edge relative to the object to be cut while maintaining its axis at 90°C. For this reason, it is necessary to adjust the cutting knife so that it always remains in the correct position, for example by inserting a shear pin into a hole that communicates the knife with the side wall of the cylinder.
