Abstract
A tool receptacle for a hand-held power tool, in particular for a demolition hammer or chisel hammer, includes—a receptacle element for receiving a tool, and a locking element which for locking the tool in the tool receptacle is mounted so as to be eccentric and rotatable on the receptacle element, wherein the locking element with the aid of rotating the latter about the receptacle element is capable of being moved from an unlocked state in which the tool is retrievable from the receptacle element to a locked state in which the locking element encompasses the tool in a form-fitting manner, and vice versa.
Claims17
A tool receptacle for a hand-held power tool, the tool receptacle comprising:
- a receptacle element for receiving a tool;
- a lock element for locking the tool in the tool receptacle, the lock element mounted so as to be eccentric and rotatable on the receptacle element, the lock element when rotated about the receptacle element being capable of being moved from an unlocked state, the tool being retrievable from the receptacle element in the unlocked state, to a locked state, the lock element encompassing the tool in a form-fitting manner in the locked state, and vice versa;
- wherein a central axis is assigned to the receptacle element, and an eccentric axis is assigned to the lock element, the lock element being rotatably mounted about the eccentric axis, wherein the eccentric axis is disposed so as to be parallel to and spaced apart from the central axis;
- and
- an eccentric element being disposed between the receptacle element and the lock element;
- wherein the lock element has a cylindrical internal geometry receiving the eccentric element, and a cylindrical external geometry disposed so as to be eccentric to the internal geometry.
A tool receptacle for a hand-held power tool, the tool receptacle comprising:
- a receptacle element for receiving a tool;
- and
- a lock element for locking the tool in the tool receptacle, the lock element mounted so as to be eccentric and rotatable on the receptacle element, the lock element when rotated about the receptacle element being capable of being moved from an unlocked state, the tool being retrievable from the receptacle element in the unlocked state, to a locked state, the lock element encompassing the tool in a form-fitting manner in the locked state, and vice versa;
- wherein the lock element has a holding collar encompassing the tool in a form-fitting manner in the locked state.
