Description

鉗clamp

本創作係與鉗有關。 This creation is related to pliers.

常見之手工具如剪刀、夾鉗、夾具等等，其大都是藉由槓桿原理來增加放大使用者手部之力量，而可以較省力之方式進行裁剪、夾持物品等作業。而此類手工具通常是透過樞軸穿設過二夾臂，讓二夾臂可相對擺動即可，整體之結構相當固定且簡約。 Common hand tools such as scissors, clamps, clamps, etc., mostly use the principle of leverage to increase the power of the user's hand, and can cut and clamp objects in a less labor-saving manner. Such hand tools usually pass through the two clamping arms through a pivot so that the two clamping arms can swing relatively, and the overall structure is quite fixed and simple.

然而，此結構存在著相當大的弊端，尤其是鉗類，即是夾口之大小受限於夾取段之長度，要長度越長的夾取段才能夠夾取較寬大的物品，或是長度較短才能夠順利夾取較小尺寸的物品，故常常會發生所欲夾取物的空間範圍無法目前使用的鉗具進行夾取之問題。 However, this structure has considerable drawbacks, especially the pliers, that is, the size of the clamping mouth is limited by the length of the gripping section, and the longer the gripping section can be used to grip larger objects, or Only a short length can smoothly grip smaller-sized objects, so there is often a problem that the space range of the object to be gripped cannot be gripped by the currently used clamps.

因此，有必要提供一種新穎且具有進步性之鉗，以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive forceps to solve the above-mentioned problems.

本創作之主要目的在於提供一種鉗，其樞軸除了可讓二夾臂進行相對擺動之外，樞軸更可以橫向移動來改變二夾臂之夾口的寬度大小，以讓使用者能使用同一支鉗進行夾取更多種尺寸的物品，如繼電器。 The main purpose of this creation is to provide a pliers whose pivot can not only allow the two gripping arms to swing relative to each other, but also the pivot can move laterally to change the width of the jaws of the two gripping arms so that users can use the same The clamp is used to clamp more kinds of size items, such as relays.

為達成上述目的，本創作提供一種鉗，包括：一第一夾臂、一第二夾臂及一樞軸。該第二夾臂貫設有一活動孔，該活動孔包含有相連通之一第一區域及一第二區域；該樞軸穿設過該活動孔地定位連結於該第一夾臂，以使該第二夾臂能以該樞軸為軸相對該第一夾臂擺動，該樞軸可選擇性地移動於該第一區域與該第二區域。 In order to achieve the above-mentioned purpose, the author provides a pliers, including: a first clamping arm, a second clamping arm and a pivot. The second clamp arm is provided with a movable hole through which the movable hole includes a first area and a second area that are communicated with each other; the pivot is positioned and connected to the first clamp arm through the movable hole to make The second clamping arm can swing relative to the first clamping arm about the pivot axis, and the pivot can be selectively moved between the first area and the second area.
