Abstract
A hammer mechanism has a clamping chuck and a snap die provided for the direct striking of an inserted tool. The snap die includes a coupling element for transmitting a rotary motion to the clamping chuck.
Claims16
A hammer mechanism of an apparatus, the hammer mechanism being configured for striking a tool inserted into the apparatus, comprising:
- a clamping chuck;
- a clamping chuck drive shaft;
- and
- a snap die configured to directly strike the inserted tool,
- wherein the clamping chuck drive shaft is joined to the snap die in a torsionally fixed and axially displaceable manner, wherein the clamping chuck drive shaft is configured to directly act on the snap die,
- wherein the snap die includes a coupling element for transmitting a rotary motion of the clamping chuck drive shaft to the clamping chuck.
A hand-held tool, comprising:
- an inserted tool element;
- and
- a hammer mechanism having a clamping chuck, a clamping chuck drive shaft, and a snap die configured to directly strike the inserted tool element, wherein the clamping chuck drive shaft is joined to the snap die in a torsionally fixed and axially displaceable manner, wherein the clamping chuck drive shaft is configured to directly act on the snap die, and wherein the snap die includes a coupling element for transmitting a rotary motion of the clamping chuck drive shaft to the clamping chuck.
A hammer mechanism of an apparatus, the hammer mechanism being configured for striking a tool inserted into the apparatus, comprising:
- a clamping chuck;
- a snap die configured to directly strike the inserted tool;
- a clamping chuck drive shaft for transmitting a rotary motion to the snap die;
- and
- a hammer element which is mounted by the clamping chuck drive shaft in a manner allowing movement in a strike direction in at least one operating state,
- wherein the snap die includes a coupling element for transmitting a rotary motion to the clamping chuck,
- wherein the clamping chuck drive shaft at least partially penetrates the hammer element.
A hammer mechanism of an apparatus, the hammer mechanism being configured for striking a tool inserted into the apparatus, comprising:
- a clamping chuck;
- a snap die configured to directly strike the inserted tool;
- a clamping chuck drive shaft for transmitting a rotary motion to the snap die;
- and
- an impact-generation deactivation unit having a blocking element which acts on the snap die parallel to a force of the clamping chuck drive shaft, in at least a drilling operation,
- wherein the snap die includes a coupling element for transmitting a rotary motion to the clamping chuck.
