Abstract
A connection connecting two tool parts includes a first tool part and a receptacle for receiving a second tool part. A clamping device clamps the tool parts together in a joined state. The connecting point further includes a retaining device that is independent of the clamping device and holds the tool parts together in the joined state.
Claims29
A connection connecting two tool parts, the connection comprising:
- a first tool part having a receptacle receiving a second tool part;
- a clamping device clamping the tool parts together in a joined state;
- and
- a retaining device for holding the first and second tool parts together in the joined state, the retaining device having an actuating element and at least one locking element operative in a locked position to engage the other of the first and second tool parts when the first and second tool parts are joined and thereby hold the first and second tool parts together, the locking element displaceably supported in one of the first and second tool parts, the actuating element slidably supported in one of the first and second tool parts, the actuating element cooperating with the locking element such that the actuating element exerts forces on the locking element, the actuating element being linearly slidable into a first functional position in which the actuating element pushes the locking element into the locked position, the locking element being acted on by a pretensioning force in the locked position which pushes the locking element into the locked position, the actuating element operative to urge the locking element into the unlocked position in response to being pressed by an operator.

A connection connecting two tool parts, the connection comprising:
- a first tool part having a receptacle for receiving a second tool part;
- a clamping device for clamping the first and second tool parts together in a joined state;
- and
- a retaining device independent of the clamping device and for holding the tool parts together in the joined state, the retaining device having at least one locking element displaceably supported in one of the tool parts, the locking element operative in a locked position to engage the other tool part when the first and second tool parts are joined, thereby holding the first and second tool parts together, the retaining device having an actuating element slidably supported in one of the tool parts that cooperates with the locking element in such a way that the actuating element exerts forces onto the locking element, the actuating element being linearly slidable into a first functional position in which the locking element is urged into the locked position, the locking element displaceable into an unlocked position in which the first and second tool parts may be separated as a result of forces acting on the actuating element, the locking element being acted on by a pretensioning force in the locked position which pushes the locking element into the locked position, the actuating element operative to urge the locking element into the unlocked position in response to being pressed by an operator.

A connection connecting two tool parts, the connection comprising:
- a first tool part having a receptacle extending along a central axis for receiving a second tool part;
- a clamping device for clamping the first and second tool parts together in a joined state;
- and
- a retaining device independent of the clamping device and for holding the first and second tool parts together in the joined state, the retaining device having a locking element supported by the first tool part, the locking element operative in a locked position to engage the second tool part when the first and second tool parts are joined, thereby holding the first and second tool parts together, the retaining device having an actuating element supported by the first tool part for movement along an axis parallel to the central axis, the actuating element cooperating with the locking element in such a way that the actuating element exerts forces onto the locking element, the actuating element being linearly slidable into a first functional position in which the locking element is urged into the locked position, the locking element displaceable into an unlocked position in which the first and second tool parts may be separated as a result of forces acting on the actuating element, the locking element being acted on by a pretensioning force in the locked position which pushes the locking element into the locked position, the actuating element operative to urge the locking element into the unlocked position in response to being pressed by an operator.
