Hand tool for processing goods

Abstract

The hand tool includes a tool part that is held in a hollow cylindrical housing body of a housing part and that includes an ultrasonic transducer with at least one piezo element, which serves for delivering ultrasonic energy to a blade that is connected to the tool part. According to the invention a plurality of piezo elements are provided, which are separated from one another by contact elements and which include each a transfer opening, which is traversed by a transducer rod that is connected, directly or indirectly, to a coupling rod that is connected in one piece to the blade and that a pressing element is provided that is connected to the transducer rod and that presses the piezo elements against a locating surface of an element which is connected, directly or indirectly, to the coupling rod and which mechanically couples the piezo elements with the coupling rod.
