Abstract
A hand-held power tool, in particular a hammer drill or a combined hammer, includes a safety coupling via which torque transmission between a motor shaft and a transmission shaft of the hand-held power tool can be established and interrupted. The safety coupling includes a coupling part at the input end and a coupling part at the output end and can be actuated by a coupling actuator. Mutually complementary catch profiles, in particular similar to a crown gear set, by which the coupling part at the input end and the coupling part at the output end can be interlocked, are arranged on the coupling part at the input end and on the coupling part at the output end.

-13. (canceled)
A hand-held power tool, comprising:
- a safety coupling, wherein a torque transmission between a motor shaft and a transmission shaft of the hand-held power tool is establishable and interruptible by the safety coupling and wherein the safety coupling includes a first coupling part at an input side and a second coupling part at an output side;
- a coupling actuator, wherein the safety coupling is actuatable by the coupling actuator;
- and
- complementary catch profiles, wherein the complementary catch profiles are respectively disposed on the first coupling part and the second coupling part and wherein the first coupling part and the second coupling part are coupleable in a frictionally locked/form-fitting manner by the complementary catch profiles.
