Abstract

Die Erfindung betrifft einen Werkzeughalter (10) für ein Elektrowerkzeug, insbesondere für einen Meißel- und/oder Bohrhammer, mit einer Werkzeugaufnahme (20) zur Aufnahme eines durch eine Einstecköffnung (28) eingeführten zylindrischen Schafts (12) eines Einsatzwerkzeugs (14). Der zylindrische Schaft (12) weist in seiner Umfangsfläche mindestens zwei diametral gegenüber liegend angeordnete Rastvertiefungen (16, 18) auf. Der Werkzeughalter (10) umfasst weiters eine mindestens zwei Verriegelungselemente (32, 34), mindestens ein Sperrelement (36) und mindestens ein Rückstellelement (38) aufweisende Verriegelungsvorrichtung (30). Beim Einschieben des zylindrischen Schaftes (12) des Einsatzwerkzeuges (14) übt das Rückstellelement (38) unterschiedliche Kräfte auf die Verriegelungselemente (32, 34) der Verriegelungsvorrichtung (30) aus.
