Abstract:
1. A hand-held power tool comprising: at least one drive unit; a working part; an electrical switch; at least one operating element which can actuate the electrical switch for activating the drive unit; and a hand-held power tool protective device, wherein the hand-held power tool protective device includes a shut-off unit comprising at least one brake pin and at least one shut-off facilitation element wherein the at least one brake pin is movably connected to the at least one shut-off facilitation element connected to the at least one operating element, wherein the shut-off unit is configured to shut-off the at least one operating element upon deactivation of the at least one operating element, and therefore, a deactivation of the drive unit via the at least one brake pin, wherein the hand-held power tool protective device includes an emergency shut-off unit, which is provided for an emergency shut-off of an operation of the tool when the at least one operating element is activated, wherein the shut-off unit and the emergency shut-off unit are at least partially integral, wherein the at least one brake pin and the at least one shut-off facilitation element cooperate with the emergency shut-off unit, wherein the emergency shut-off unit comprises an electromechanical unit and a connecting unit, wherein the connecting unit includes at least one connecting element which engages in a recess of the at least one shut-off facilitation element to hold the at least one brake pin in a switch position for an emergency shut-off, and wherein the electromechanical unit is provided to allow a movement of the at least one connecting element out of the recess to allow a movement of the at least one shut-off facilitation element to move the at least one brake pin for braking the working part during an emergency shut-off.
