Abstract
The device consists of two grab elements, each with a grab jaw section and a lever arm section. The lever arm sections are charged by a movable power-transmitting element, which is tensioned against the lever arm sections by a tensioner device. An actuator is formed by a piezo adjusting element, which is charged by an electrical control voltage. This lengthens the element in the direction of the lever arm sections, so that it presses against the power-transmitting element, which in turn is driven in the direction of the lever arm sections. This causes the grab jaws to move about joints, and towards each other. ADVANTAGE - Simple to manufacture, modular construction.
