    • A gripping device comprises a support body (2) within a sleeve (8), with the sleeve being mounted around the body for relative translational movement along a common axis thereof. A plurality of gripping elements (10, 12) are pivotally mounted in the body (2), the elements having lever arms (20, 22) projecting laterally from the boundary of the body. Translational movement of the sleeve (8) relative to the body (2) causes working engagement of the sleeve with the gripping element lever arms (20, 22), and movement of the lever arms to pivot the elements (10, 12) and close the elements around an item captured therebetween. Normally, the pivotal axes for the gripping elements (10, 12) are disposed within the support body (2), with the elements themselves projecting axially from an end thereof. The pivotal axes are normally substantialy parallel, and indeed the gripping elements may all be mounted for pivotal movement about the same common axis (18). The pivotal axis or axes will usually be perpendicular to the common axis of the support body and sleeve, but there may be applications in which a different angular relationship between these axes will be used.
    • 一种夹持装置包括在套筒(8)内的支撑体(2),该套筒围绕该体安装,用于沿着其公共轴线进行相对平移运动。 多个夹紧元件(10,12)枢转地安装在主体(2)中,元件具有从主体的边界横向突出的杠杆臂(20,22)。 套筒(8)相对于本体(2)的平移运动引起套筒与夹持元件杠杆臂(20,22)的工作接合,并且杠杆臂的运动使元件(10,12)枢转并且闭合 物品周围的元素被捕获在其间。 通常,夹紧元件(10,12)的枢转轴线设置在支撑体(2)内,元件自身从其端部轴向突出。 枢转轴线通常基本上是平行的,并且实际上抓握元件可以全部安装成绕同一公共轴线(18)枢转运动。 一个或多个枢轴通常垂直于支撑体和套筒的公共轴线,但可能存在这些轴线之间将使用不同角度关系的应用。
