[Technical field to which the invention belongs]

本考案は、普通のドライバーでは緩めることができない、錆付いたネジや頭の潰れたネジの緩め作業や、特に強く締め付ける作業に用いるインパクトドライバーに関するものである。 The present invention relates to an impact driver used for loosening a rusted screw or a screw with a crushed head, which cannot be loosened by a normal screwdriver, and particularly for strongly tightening work.

【０００２】[0002]

[Prior art]

従来のインパクトレンチは、図３に示す如く錆付いたネジや、頭の潰れたネジＮの頭部溝内にしっかりとビットＢの先を挿入する必要があり、しかも本体の握り柄Ｔの頭部からハンマーＨで叩く構成上必然的に握り柄Ｔは、ビットＢと一直線上に設けられており、指Ｕでしっかりと握り締めて作業を行なう構成となっていた。 In the conventional impact wrench, as shown in Fig. 3, it is necessary to firmly insert the tip of the bit B into the head groove of a screw N with a rusted screw or a crushed head, and the head of the grip handle T of the main body. The grip handle T is inevitably provided on the straight line with the bit B in the structure of hitting with the hammer H from the portion, and the work is performed by firmly gripping with the finger U.

[Problems to be solved by the device]

しかしながら、従来のものは鏨と同じようにビットＢと握り柄Ｔとが一直線上に存在するために力強く握り締めることができ安定性もよくハンマーで強く叩くことができる利点がある反面、ハンマーで頭部を打ち損なうと手を強打して傷付くことがあり、しかも近来は、組立て部品類が複雑、且つ、小型化される傾向にあるので図２に示す如くネジＮが組立て部品Ｋの角や隅の狭い場所に使用されることが多くなり、握り締めた指が入らなくて使用できないケースが増大し、そのために角や、隅等の狭い場所の強力ネジ締め作業や、錆付きネジのゆるめ作業に適するインパクトドライバーの開発が強く望まれていた。本考案はこれらの要求に鑑み、これに対応できるインパクトドライバーを提供する目的で考案されたものである。 However, the conventional one has the advantage that the bit B and the grip handle T are on the same straight line as the chisel, so that the grip can be strongly gripped and the stability is good and the hammer can be hit strongly with the hammer. If the part is missed, the hand may be struck and scratched, and recently, since the assembled parts tend to be complicated and downsized, as shown in FIG. It is often used in places with tight corners and corners, which increases the number of cases in which a finger cannot be used because it cannot be gripped with fingers, so it is necessary to tighten strong screws in tight places such as corners and corners, and to remove rusted screws. There was a strong demand for the development of an impact driver suitable for loosening work. In view of these requirements, the present invention was devised for the purpose of providing an impact driver capable of meeting these requirements.

[Means for Solving the Problems]

本考案は、本体の側面に本体の長手方向と直角方向に本体に対してＴ字形に握り柄を取付ける。 In the present invention, a grip handle is attached to the side surface of the body in a T-shape with respect to the body in a direction perpendicular to the longitudinal direction of the body.

【０００５】[0005]

[Embodiment of the invention]

本体１は、例えばハンマーで頭部を叩くと、バネの力に抗して本体１は降下し本体１の円胴内部に嵌入したスチールボールがビット取付軸２の外周面に回転方向に窪設したカム溝内を降下して横方向の回転力に変換する従来のインパクトドライバーと同様の回転機構を内蔵組付けする。握り柄４は、本体１の側面３に、本体１の長手方向と直角方向に本体１にＴ字形状に取付ける。ビット５はビット取付軸２に根元部を挿嵌して取付ける。 When the head of the main body 1 is hit with a hammer, for example, the main body 1 is lowered against the force of the spring, and the steel ball fitted inside the cylinder of the main body 1 is dented in the rotation direction on the outer peripheral surface of the bit mounting shaft 2. A rotary mechanism similar to the conventional impact driver that descends in the established cam groove and converts into a lateral rotation force is built in. The grip handle 4 is attached to the side surface 3 of the main body 1 in a T-shape on the main body 1 in a direction perpendicular to the longitudinal direction of the main body 1. The bit 5 is mounted by inserting the root portion into the bit mounting shaft 2.

【０００６】[0006]

[Effect of the invention]

以上述べた如く、本考案は本体を直接に手で握らなくてもよいためにハンマーで本体部分を打つ時に打ち損ねても手を打って傷付く懸念が無くなり、また、指の入る隙間がないくらいネジが部品の角や隅の狭い場所にあっても使用が可能である。 As described above, according to the present invention, since the main body does not have to be directly held by the hand, there is no concern that the hand may be damaged even if the body is hit with a hammer, and there is no space for fingers to enter. It can be used even when the screws are in places with narrow corners or corners.
