Description

本考案は、工具継手に関する。 The present invention relates to a tool joint.

一般に、ロック作業を行う時、空気又は電動のいずれかの回転工具を用いてロック部材に接続してロックするが、従来の回転工具の駆動端に駆動レバーが設けられ、駆動レバーはロック部材に接続され、駆動レバーがロック部材に接続されることにより、駆動端が回転すると、レバーを回転駆動させてロック作業を行う。しかしながら、ロック部材が多種の仕様（例えば、ねじ、ナット及びボルト等）を有するため、実際の作業時に、駆動端は、スリーブ又は他の工具に接続されるように異なる駆動レバーを交換する必要があり、それによりナット又はボルト等のロック部材をロックすることができ、このように使用には不便であり、改善すべき欠点がある。 Generally, when performing locking work, a drive lever is provided at the drive end of a conventional rotary tool, and the drive lever is attached to the lock member, although it is connected to and locked to the lock member using either an pneumatic or electric rotary tool. When the drive end is rotated by being connected and the drive lever is connected to the lock member, the lever is rotationally driven to perform the locking operation. However, because the locking member has a variety of specifications (eg, screws, nuts and bolts, etc.), during actual work the drive end will need to be replaced with a different drive lever to connect to the sleeve or other tool. Yes, it can lock locking members such as nuts or bolts, which is inconvenient to use and has drawbacks to be improved.

そこで、上記した問題を解決するために、新規で進歩性のある工具継手を提供する必要がある。 Therefore, in order to solve the above-mentioned problems, it is necessary to provide a new and inventive step tool joint.

本考案は、自動回転工具とロック工具とを中継することができ、構造が簡単だけでなく操作が迅速に便利である工具継手を提供することを主な目的とする。 The main object of the present invention is to provide a tool joint that can relay between an automatic rotary tool and a lock tool, and is not only simple in structure but also quick and convenient to operate.

上記の目的を達成するために、本考案の工具継手は、本体、中継部材、弾性部材及び少なくとも１つの受止部材を含む。該本体は、径方向に貫通孔が開設された接続部が設けられ、係止部材が該貫通孔に移動可能に収容される。該中継部材は、該本体に挿設されて第１位置と第２位置に移動可能であり、該中継部材が該第１位置に位置する時、該中継部材が該係止部材に径方向に押圧し、該係止部材を径方向の外向きに押圧させ、該中継部材が該第２位置に位置する時、該中継部材が該係止部材に押圧されず、該係止部材を径方向の内向きに移動可能にさせる。該弾性部材は、該本体と該中継部材との間に当接し、該中継部材を常に該第１位置に向けて移動させる。該少なくとも１つの受止部材は、該本体に設けられ、該中継部材が該本体から離脱することを回避するように該中継部材を受け止める。 In order to achieve the above object, the tool joint of the present invention includes a main body, a relay member, an elastic member and at least one receiving member. The main body is provided with a connecting portion having a through hole formed in the radial direction, and the locking member is movably accommodated in the through hole. The relay member is inserted into the main body and can move to the first position and the second position, and when the relay member is located at the first position, the relay member is radially attached to the locking member. Press and press the locking member radially outward, and when the relay member is located at the second position, the relay member is not pressed against the locking member and the locking member is pressed radially outward. Make it movable inward. The elastic member abuts between the main body and the relay member, and the relay member is always moved toward the first position. The at least one receiving member is provided on the main body and receives the relay member so as to prevent the relay member from detaching from the main body.
