Description

本考案は手工具に関し、特にラチェットレンチに関する。   The present invention relates to hand tools, and in particular to ratchet wrench.

図５に示すように、ラチェットレンチ９０の構造はグリップ９１、駆動部材９２、カバーリング９３、Ｃ形状のスナップリング９４、爪９５、切換部材９６および位置決め部材９７を備える。該駆動部材９２は該グリップ９１のヘッド９１２内で回転し、該カバーリング９３は該駆動部材９２の上面に套設されている。また、該Ｃ形状のスナップリング９４は該ヘッド９１２と該カバーリング９３とをそれぞれ嵌合し、該駆動部材９２の位置を固定するために用いられる。該爪９５は該グリップ９１の収容室９１４内に設けられ、かつ該駆動部材９２と噛合する。該切換部材９６は連結棒９６２を有し、該連結棒９６２は該爪９５の固定孔９５２を貫通するように設けられ、該切換部材９６が該爪９５を移動できるようにする。該位置決め部材９７は該収容室９１４に設けられ、該爪９５と接触し、該爪９５を該駆動部材９２に緊接させるようにする。   As shown in FIG. 5, the structure of the ratchet wrench 90 includes a grip 91, a driving member 92, a cover ring 93, a C-shaped snap ring 94, a claw 95, a switching member 96, and a positioning member 97. The drive member 92 rotates within the head 912 of the grip 91, and the cover ring 93 is provided on the upper surface of the drive member 92. The C-shaped snap ring 94 is used to fit the head 912 and the cover ring 93 and fix the position of the driving member 92. The claw 95 is provided in the accommodation chamber 914 of the grip 91 and meshes with the driving member 92. The switching member 96 has a connecting rod 962, and the connecting rod 962 is provided so as to penetrate the fixing hole 952 of the claw 95 so that the switching member 96 can move the claw 95. The positioning member 97 is provided in the storage chamber 914 and comes into contact with the claw 95 so that the claw 95 is brought into tight contact with the driving member 92.

しかしながら、上述のラチェットレンチ９０の構造において、該切換部材９６の連結棒９６２の断面形状と該爪９５の固定孔９５２とは共に多辺形であり、該連結棒９６２を該固定孔９５２に穿設する時には必ず該連結棒９６２の方向を再調整しなければならず、該連結棒９６２と該固定孔９５２とが互いに対応するに至ってやっと該連結棒９６２がスムースに該固定孔９５２の中で穿設されることが可能となるため、組立上の面倒さをもたらしていた。このほか、該切換部材９６は該グリップ９１のヘッド９１２に位置し、且つ該切換部材９６の端縁は該ヘッド９１２の頂端よりも高く、ユーザーが不注意によって容易に該切換部材９６の切換を行うことをもたらし、これは該爪９５の位置を変え、該駆動部材９２の回転方向を変えることになり、ユーザーにとって使用上における不便となっていた。   However, in the structure of the ratchet wrench 90 described above, the cross-sectional shape of the connecting rod 962 of the switching member 96 and the fixing hole 952 of the claw 95 are both polygonal, and the connecting rod 962 is formed in the fixing hole 952. When installing, the direction of the connecting rod 962 must be readjusted, and only when the connecting rod 962 and the fixing hole 952 correspond to each other, the connecting rod 962 smoothly enters the fixing hole 952. Since it can be drilled, it has been troublesome in assembling. In addition, the switching member 96 is positioned on the head 912 of the grip 91, and the edge of the switching member 96 is higher than the top end of the head 912, so that the user can easily switch the switching member 96 inadvertently. This changed the position of the claw 95 and changed the direction of rotation of the drive member 92, which was inconvenient for the user.

The column 82 has a cylindrical shaft portion 822, and has a hemispherical body 824 extending forward from the shaft portion 822, and a terminal portion 826 extending rearward from the shaft portion 822 and having a cylindrical shape. ing. The hemisphere 824 contacts the recess 66 of the pawl 60 and the diameter of the end 826 is smaller than the diameter of the shaft 822 and can be used to mate with the spring 84. One end of the spring 82 contacts the bottom surface of the shaft portion 822 of the column 82, and the other end of the spring 84 contacts the inner wall of the receiving hole 229. The spring 84 provides elasticity and pushes the column 82 in the direction of the claw 60 so that the claw 60 can be brought into tight contact with the drive member 30.

本実施例によるラチェットレンチ１０において、図２が示す該グリップ２０のヘッド２２および取付け部２４は鉄削加工を経て作製され、本実施例を組立てる時にはまず、該柱８２および該スプリング８４を該グリップ２０の収容孔２２９内に置き、該爪６０は直接該収容室２２６内に入れ、該柱８２を該爪６０の凹部６６で接触するようにし、続いて該カバーリング４０および該スナップリング５０を再度利用して、該駆動部材３０を該貫通孔２２２内に固定し、該爪６０と該駆動部材３０を互いに噛合させ、さらに該切換部材７０のボディ７４を該爪６０の固定孔６２に穿設し、且つ該切換部材７０の凸壁７６を該カバーリング４０内に嵌設する。このとき、該切換部材７０のヘッド７２底面は該取付け部２４と接触し、該切換部材７０の端縁と該グリップ２０のヘッド２２端縁が同じ水平面の位置となるようにする。このようにして、該切換部材７０の切換が可能となり、該爪６０の移動のために用いられ、該駆動部材３０の回転方向を制止する。図３に示すように、該切換部材７０を切換することにより、該爪６０を該収容室２２６の側面図中左側に動かし、該駆動部材３０を反時計周りに回転させることができる。図４に示すように、もしも該切換部材７０が該爪６０を収容室２２６のもう一つの側面図中右側に移動させる場合、該駆動部材３０は時計回りに回転することができる。すなわち、本実施例が提供するラチェットレンチにより、組立が容易で、且つ使用に便利となる目的を達成することができた。   In the ratchet wrench 10 according to the present embodiment, the head 22 and the mounting portion 24 of the grip 20 shown in FIG. 2 are manufactured by ironing, and when assembling the present embodiment, the column 82 and the spring 84 are first attached to the grip. 20 in the receiving hole 229, the claw 60 is directly placed in the receiving chamber 226 so that the pillar 82 is in contact with the recess 66 of the claw 60, and then the cover ring 40 and the snap ring 50 are moved. The driving member 30 is fixed in the through hole 222 again, the claw 60 and the driving member 30 are engaged with each other, and the body 74 of the switching member 70 is drilled in the fixing hole 62 of the claw 60. And the convex wall 76 of the switching member 70 is fitted into the cover ring 40. At this time, the bottom surface of the head 72 of the switching member 70 is in contact with the mounting portion 24 so that the edge of the switching member 70 and the edge of the head 22 of the grip 20 are on the same horizontal plane. In this way, the switching member 70 can be switched and used for the movement of the claw 60 to stop the rotation direction of the drive member 30. As shown in FIG. 3, by switching the switching member 70, the claw 60 can be moved to the left side in the side view of the storage chamber 226 and the driving member 30 can be rotated counterclockwise. As shown in FIG. 4, if the switching member 70 moves the claw 60 to the right side in the other side view of the storage chamber 226, the drive member 30 can rotate clockwise. That is, the ratchet wrench provided by the present embodiment achieved the purpose of easy assembly and convenient use.
