合部とが形成されている点にある。Therefore, the present invention provides a special tool for easily removing such a retaining ring.The feature of the present invention is that the inner fitting member is fixedly fitted into the circumferential groove of the cylindrical sleeve. In addition, in order to remove the milk retaining ring that has a straight part that protrudes radially inward,
A retaining ring removal tool having an elongated tool body whose tip can be engaged with a retaining ring, and a grip portion for rotating the tool body around one side edge of the tool body, the retaining ring removal tool comprising: The distal end is formed to be thinner and wider than the width of the gap between the inner circumferential surface of the cannula and the linear portion of the retaining ring. By rotating approximately 90 degrees after making contact, a pointed biting part protrudes radially inward to bite into between the straight part and the internal fitting member, and a straight line on the side of the grip part from this biting part. An engaging portion is formed which engages with the portion and prevents relative movement in the longitudinal direction.
以下図面に基づき本考案の実施例を詳述すると、第３図
乃至第５図において、１０は一枚の板材を打抜いて形成

込部１３と係合部１４と案内部１５とを備えている。Embodiments of the present invention will be described below in detail based on the drawings. In FIGS. 3 to 5, reference numeral 10 denotes a retaining ring removal tool formed by punching out a single plate, which includes a tool body 11 and a grip part 12. , a biting part 13 , an engaging part 14 , and a guide part 15 .
工具本体１１はプラグ本体１内の正編５位置に応じて成
る一定の長さを有する。The tool body 11 has a constant length depending on the position of the regular stitch 5 in the plug body 1.
握り部１２は工具本体１０の一端部に、該工具本体１１
の長手方向と略直交方向に一体に突設されている。The grip portion 12 is attached to one end of the tool body 10 and
It protrudes integrally in a direction substantially orthogonal to the longitudinal direction.
また工具本体１１と握り部１２との連結部付近には指を
引掛ける開口孔１６が形成されている。Further, an opening hole 16 for hooking a finger is formed near the connecting portion between the tool body 11 and the grip portion 12.
食込部１３は絶縁体３と正編５間に食込む部分であって
、該食込部１３は工具本体１１の他端に、該工具本体１
１の長手方向に対し略直交方向外方に突出するように鋭
利に形成されている。The biting part 13 is a part that bites between the insulator 3 and the regular stitch 5, and the biting part 13 is attached to the other end of the tool body 11.
It is sharply formed so as to protrude outward in a direction substantially orthogonal to the longitudinal direction of the first part.
保合部１４は正編５に形成された直線部５ａと係合する
部分であって、該係合部１４は食込部１３よりも握り部
１２側で且つ工具本体１１下部の食込部１，３突設側に
、該工具本体１１の下端面と略平行に形成されている。The retaining part 14 is a part that engages with the straight part 5a formed in the regular stitch 5, and the engaging part 14 is located closer to the grip part 12 than the biting part 13 and to the biting part in the lower part of the tool body 11. It is formed on the protruding side of 1 and 3 so as to be substantially parallel to the lower end surface of the tool body 11.
案内部１５は正編５を食込部１３より係合部１４へ案内
する部分で、食込部１３の傾斜に連続する傾斜面を有し
、該食込部１３と係合部１４を相互に接続している。The guide part 15 is a part that guides the regular stitch 5 from the biting part 13 to the engaging part 14, and has an inclined surface that is continuous with the slope of the biting part 13, and connects the biting part 13 and the engaging part 14 to each other. is connected to.
上記構成の正編取外工具１０による取外動作を、第６図
に基いて説明する。The removal operation by the regular stitch removal tool 10 having the above configuration will be explained based on FIG. 6.
円筒状套嵌体としてのプラグ本体１の内周面１ａの周溝

Ａが形成されており、この間隙Ａへ内周面１ａに沿って
プラグ本体１内へ配置してきた工具本体１１の先端部（
下端）を挿入する（第６図１参照）。The milk regular section 5 fitted into the circumferential groove 4 of the inner circumferential surface 1a of the plug body 1 as a cylindrical sleeve has a straight portion 5a that partially projects radially inward, so that the inner circumferential A gap A is formed between the surface 1a and the tip of the tool body 11 (
(lower end) (see Figure 6, 1).
工具本体１１の先端部は間隙Ａの幅（内周面１ａとの径
方向距離）よりも薄肉広幅に形成されているので、間隙
Ａへ容易に挿入でき、その先端は正編５に当接して位置
規制された内嵌部材としての絶縁体３の端面に当接する
。The tip of the tool body 11 is formed to be thinner and wider than the width of the gap A (radial distance from the inner circumferential surface 1a), so it can be easily inserted into the gap A, and the tip comes into contact with the regular stitch 5. It abuts against the end surface of the insulator 3, which serves as an internally fitted member whose position is regulated.

When rotated approximately 90° around a, the pointed biting portion 13 protrudes radially inwardly than the straight portion 5a, and the straight portion 5
It digs into between a and the insulator 3.
食込部１３は尖端状であり案内部１５が形成されている
ので、直線部５ａは案内部１５によって保合部１４へ案
内される。Since the biting part 13 has a pointed shape and is provided with a guide part 15, the straight part 5a is guided to the retaining part 14 by the guide part 15.

The straight part 5a is pulled together with the engaging part 14, and the regular part 5
is separated from the circumferential groove 4 (see Fig. 6, 1).

きる。As shown in FIG. 7, the engaging portion 14 can be formed by making the biting portion 13 largely protrude from the tool body 11 so that both 11 and 13 can be connected to each other.
The grip portion 12 may be formed by a corner portion of the tool body 11, and the grip portion 12 may be formed by an eighth
As shown, the tool 10 can be shaped like a T-shape.

にする。Detailed description above 1-According to the present invention, there is provided a tool for removing the milk regular stitch fixing the inner fitting member in the mantle, the tip of which is connected to the inner circumferential surface of the mantle in a straight line. Since it is thinner and wider than the width of the gap, the tip can be inserted into the gap and come into contact with the internal fitting member, and the tip can be inserted into the gap radially inward with the tool rotated approximately 90 degrees. Since a protruding biting part is formed, biting can be done between the regular stitch and the inner fitting member, and an engaging part is formed at the tip of the part closer to the grip part than the biting part. Therefore, when the biting part bites in, it can engage with the straight part and prevent relative movement in the longitudinal direction of the tool, thereby pulling the straight part integrally when the tool is moved in the longitudinal direction. This makes it possible to reliably separate the regular stitch from the circumferential groove.
したがって実用性に富み実益大と言える。Therefore, it can be said to be highly practical and beneficial.
