本考案は、ラチエツト式手動工具の改良に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a ratchet type hand tool.
従来、手動切断工具、手動圧着工具等におい
て、より大きな切断力、圧着力をひき出す為に、
ラチエツト機構を用いたものが種々見られた。 Conventionally, in manual cutting tools, manual crimping tools, etc., in order to draw out greater cutting force and crimping force,
Various models using ratchet mechanisms were seen.
しかし、これら各種工具に使用されているラチ
エツト機構の１例を第１図に示す。即ち、図は一
方の把手１の先端部に、切断するパイプの受け部

ツト爪９を常時ラチエツト８に向かつて付勢する
ばね１４を設けることにより構成される。そし
て、把手２を手動で揺動される毎にラチエツト爪
９がラチエツト８と係合して、切断刃４を受け部
３′に向かつて少しづつ回動させるのである。 However, one example of a ratchet mechanism used in these various tools is shown in FIG. That is, in the figure, a receiving part 3' for the pipe to be cut is integrally provided at the tip of one handle 1, and the other handle 2 is pivotally attached to the handle 1 so as to be able to swing in the direction toward and away from the handle. This pipe cutter has a cutting blade 4 pivotably attached to the tip of the handle 2. A ratchet 8 is carved in the rear end of the cutting blade 4, and the base of a ratchet pawl 9 is pivotally attached to a portion near the tip of the handle 2, and a spring 14 is provided to constantly bias the ratchet pawl 9 toward the ratchet 8. It is constituted by providing. Each time the handle 2 is manually swung, the ratchet pawl 9 engages with the ratchet 8 to rotate the cutting blade 4 little by little toward the receiving portion 3'.
従つて、切断刃４のストロークを大きくとつて
も切断刃４に加わる力を大きくすることができる
こととなる。 Therefore, even if the stroke of the cutting blade 4 is increased, the force applied to the cutting blade 4 can be increased.
しかし、把手２の枢着位置とラチエツト爪９の
枢着位置とは、ラチエツト爪９自体の強度を大き
くしなければならない関係上、余に接近させるこ
とができず、また、把手１，２自体の長さも手動
操作の便宜上、余り長くすることができないの
で、切断刃４に加え得る力には限度があつた。 However, the pivot position of the handle 2 and the pivot position of the ratchet pawl 9 cannot be made very close to each other because the strength of the ratchet pawl 9 itself must be increased. The length of the cutting blade 4 cannot be made too long for convenience of manual operation, so there is a limit to the force that can be applied to the cutting blade 4.
本考案は、切断刃等作動部に加え得る力を著し
く大きくできるラチエツト機構を装設したラチエ
ツト式手動工具に関するものであり、以下実施例
を示す添付図面によつて詳細に説明する。 The present invention relates to a ratchet type manual tool equipped with a ratchet mechanism that can significantly increase the force that can be applied to an operating part such as a cutting blade, and will be described in detail below with reference to the accompanying drawings showing embodiments.

５にて連結している。 FIG. 2 is a side view of a cutter for cutting wires, tree branches, etc., and FIG. 4 is a sectional view taken from FIG. One of the cutting blades 3 is fixed to the tip of the wide part 1' by shafts 6 and 7, and the other cutting blade 4 is rotatably pivoted by the shaft 7. The other handle 2 is pivotally attached to the upper and rear ends on a shaft 12, and the handle 2 and the cutting blade 4 are connected by a ratchet mechanism 5, which is the main feature of the present invention. ing.

手２に支持させている。 The ratchet mechanism 5 includes a ratchet 8 having an arcuate surface carved at the rear end of the cutting blade 4, and a circular hole 1 at the base.
It consists of a ratchet pawl 9 with a hole drilled at 0, and a disc-shaped driven shaft 11 inserted into the circular hole 10. A shaft 13 is inserted into a predetermined position opposite to the insertion position, and both ends of the shaft 13 are supported by the handle 2.

15 is the ratchet pawl 9
16 is a stopper provided on the handle 1 so as to be able to engage with the ratchet 8; 17 is a recessed groove for engaging the spring 14 recessed in a predetermined position of the ratchet pawl 9; 18 is a groove for engaging the cutting blade 4; This is a spring that urges the blade away from the cutting blade 3.
以上の構成になるカツターの作用は次のとおり
である。 The function of the cutter having the above structure is as follows.
第２図に示す状態において、把手２を把手１に
向かつて揺動すれば、該把手２に軸１３で連結さ
れた従動軸１１も軸１２を中心として回動する。
そして、円板状の従動軸１１は所定距離把手１に
接近するとともに、切断刃３にも接近する。 In the state shown in FIG. 2, when the handle 2 is swung toward the handle 1, the driven shaft 11 connected to the handle 2 by a shaft 13 also rotates about the shaft 12.
Then, the disk-shaped driven shaft 11 approaches the handle 1 by a predetermined distance and also approaches the cutting blade 3.
従つてラチエツト爪９も、該従動軸１１の移動
に追従しようとするのであるが、ラチエツト８と
係合しているので、揺動しながら把手１に向かつ

次いで把手２を釈放すれば、ばね１４の弾力に
て第２図に示す原位置まで復動し、以下上記操作
を反復することにより、ワイヤー、植木の枝等を
切断することができる。 Therefore, the ratchet pawl 9 also tries to follow the movement of the driven shaft 11, but since it is engaged with the ratchet 8, it moves toward the handle 1 while swinging, thereby causing the cutting blade 4 to move. Cutting blade 3 for a predetermined distance
It can be rotated to face. (See Figure 3) Next, when the handle 2 is released, it moves back to the original position shown in Figure 2 by the elasticity of the spring 14, and by repeating the above operation, wires, branches of plants, etc. can be cut. be able to.
第５図はパイプカツターに応用した実施例を示

ね１８により自動的に復帰する。 In any of the above cases, the handle 2 is swung far away from the handle 1 to disengage the ratchet 8 and the ratchet pawl 9, and the stopper 16 is operated to separate the stopper 16 and the ratchet 8. When the cutting blade 4 is disengaged, the spring 18 automatically returns the cutting blade 4 to its original position.
また、切断刃４に加えられる力は、従動軸１１

に切断できる。 In addition, the force applied to the cutting blade 4 is
By using the cutter, the cutter is significantly stronger (more than 50% stronger than the conventional cutter), and can easily cut pipes, tree branches, etc. that are too thick to cut with the cutter shown in Fig. 1.
以上は、カツターに応用した実施例についての
み説明したが、本考案の手動工具はカツターのみ
に限定されるものでは全くなく、圧着工具、パン
チング工具等にも応用できることは勿論である。 Although only the embodiments applied to cutters have been described above, the hand tool of the present invention is not limited to cutters at all, and can of course be applied to crimping tools, punching tools, etc.
以上のように、本考案はラチエツト爪を円板状
