A hand power tool has a housing, and drive motor accommodated in the housing, a tool receptacle in which a tool is guided, a gear mechanism, a driving gear, and rotary sleeve arranged so that via the gear mechanism, the driving gear, and the rotary sleeve the tool receptacle is drivable in rotation, a crank drive mechanism and a hammering mechanism located inside the rotary sleeve so that the tool receptacle is drivable through the crank drive mechanism and the hammering mechanism translationally, and a safety coupling provided between the driving gear wheel and the rotary sleeve and formed so that the safety coupling separates if a limit torque is exceeded, the safety coupling being formed as an overlock coupling seated on the rotary sleeve and having two axially adjacent coupling parts that mesh in a form-locked manner by torque-transmitting transmission elements and are overlockable if the limit torque is exceeded counter to an axially acting elastic force, one of the coupling parts being a part associated with the driving gear wheel and rotatable relative to the rotary sleeve while the other of the coupling parts is coupled to the rotary sleeve in a way that transmits torque.
