    摘要： Clamp capable of mechanical clamping and optionally useful for providing especially high electrical conductivity having a pair of juxtaposed clamping jaws for gripping an object. One important use of the clamp is to grip an article through which high current is required to flow as, for example, in electric welding. At least one of the jaw blocks is of deep case-hardened cold rolled steel, and when used for high electrical conductivity, is copper coated. The face of this block is provided with concentric teeth which bite into the article. The outer faces of the teeth are perpendicular to the surface of the article being gripped. This inhibits skidding of the clamp and also provides good electrical contact where needed, even in the presence of rust or corrosion. The circular shape of teeth permits rotation or oscillation of the clamp during the clamping operation, which facilitates cleaning of the engaged surfaces and enhances electrical conductivity. Such a low resistance electrical connection permits high current flow with relatively little power loss. In a form of the clamp there are a plurality of sets of concentric teeth, with teeth of one set intersecting teeth of another set. The teeth for the jaw block can be cut by a cutter in a tool holder which is adapted for rotation.

    摘要翻译： 夹具能够进行机械夹紧，并且可选地用于提供特别高的导电性，具有用于夹持物体的一对并置的夹爪。 夹具的一个重要用途是夹紧需要高电流流动的物品，例如电焊。 至少一个颚板是深度硬化的冷轧钢，当用于高导电性时，是镀铜的。 该块的表面设置有咬入物品的同心齿。 齿的外表面垂直于被夹紧物品的表面。 这阻止了夹具的打滑，并且在需要时也提供良好的电接触，即使在存在锈蚀或腐蚀的情况下也是如此。 齿的圆形允许在夹紧操作期间夹具的旋转或振动，这有助于清洁接合表面并增强导电性。 这种低电阻电连接允许具有相对小的功率损耗的高电流流动。 在夹具的形式中，存在多组同心齿，其中一组的齿与另一组的齿相交。 用于钳口块的齿可以由适于旋转的工具夹中的切割器切割。
