The invention relates to a hand-held machine tool having an electric motor 7 and an output shaft 1 which can be driven by the electric motor 7 in a rotational manner about a working axis 18. The output shaft 1 comprises an cylindrical or prismatic intake space 16 that is oriented along a working axis 18 and is open on the output shaft, for receiving a machine tool 11 against a removal direction 20 and two elongated holes 19 cutting into the intake space 16 in the radial direction. The elongated holes comprise in each case a blocking element 12 that lies in the elongated hole 19 and protrudes into the intake space 16 and that is movable between an end on the output side 22 of the elongated hole 19 and an end on the actuation side 21 of the elongated hole 19. The blocking element 12 abuts on a radial stop 26 in radial direction and is forced into the intake space in an engaging manner. The stop 26 overlaps in a locked position with the ends on the output side 22 of the elongated holes 19 and can be moved in the removal direction 20 against a spring force of a spring 23 for releasing a radial movement of the blocking element 12 from the engagement with the intake space 16. A spring 23 comprises a support ring 29, two bows 30 protruding from the support ring 29 into the removal direction 20 and bent around the intake space in the form of a segment of a circle, and a pin 36 engaging radially from each bow 30 in the removal direction 20 in front of the blocking element 12 into the elongated hole 19. |
