Description

本考案は、挟持工具に関するものである。   The present invention relates to a clamping tool.

従来から、例えば特開２０１１−１３１３７５に開示されるような挟持工具（以下、従来例という）が提案されている。   Conventionally, for example, a clamping tool (hereinafter referred to as a conventional example) as disclosed in JP2011-131375 has been proposed.

この従来例は、一対の半体同士を回動自在に重合連結し、この半体同士の重合連結部の基端側に設けられる開閉操作部の操作により先端側に設けられる挟持作業部を開閉動させるように構成されたもので、半体夫々の挟持部内面に合成樹脂製の挟持部材が着脱自在に設けられている。   In this conventional example, a pair of halves are connected to each other in a rotatable manner, and a clamping work portion provided on the distal end side is opened / closed by an operation of an opening / closing operation portion provided on the proximal end side of the overlapping connection portion between the halves. It is configured to be moved, and a holding member made of synthetic resin is detachably provided on the inner surface of the holding portion of each half body.

従って、従来例は、被挟持物に当接する部位が合成樹脂製である為、該被挟持物を傷つけずに挟持することができ、しかも、挟持部材は着脱自在である為、挟持部材が破損した場合など、取り換えも可能である。   Therefore, in the conventional example, the portion that comes into contact with the object to be sandwiched is made of synthetic resin, so that the object to be sandwiched can be sandwiched without damaging, and the sandwiching member is detachable, so that the sandwiching member is damaged. It is also possible to replace it.

特開２０１１−１３１３７５号公報JP 2011-131375 A

ところで、この従来例における半体夫々の挟持部内面に対する挟持部材の取付けは、挟持部材に貫通形成された螺子穴に螺子を螺子頭が内方に位置する状態で螺着して取付ける構造である。   By the way, the attachment of the clamping member to the inner surface of the clamping part of each half body in this conventional example is a structure in which a screw is screwed into a screw hole penetratingly formed in the clamping member with the screw head positioned inward. .

従って、従来例は、挟持部材の取付けに際し、螺子の螺着作業は必須となり、手間がかかることは勿論、螺子の螺子頭が挟持部材から突出しないように、挟持部材に形成した凹部に螺子頭を位置させなければならず（金属製の螺子頭を被挟持物に当接させないため）、それだけ挟持部材の強度が低下し、更に、この螺子の存在により被挟持物との当接面積が小さくなって挟持作用に障害を生じさせる。しかも、螺子や螺子穴が破損することで挟持部材の取り換えができなくなる場合も生じる。   Therefore, in the conventional example, when the clamping member is attached, the screwing operation of the screw is indispensable, which is troublesome. Of course, the screw head is inserted into the recess formed in the clamping member so that the screw head of the screw does not protrude from the clamping member. (To prevent the metal screw head from coming into contact with the object to be held), the strength of the holding member is reduced accordingly, and the presence of this screw reduces the contact area with the object to be held. It causes trouble in the pinching action. In addition, there are cases where it becomes impossible to replace the holding member due to damage to the screw or screw hole.

本考案は、前述した問題点を解消するもので、非常に実用的な挟持工具を提供する。   The present invention solves the above-mentioned problems and provides a very practical clamping tool.
