摘要

For a machine hand tool (10), in particular a circular hand saw (50), having a machine housing (11) with a front mounting surface (33), said machine housing accommodating a drive motor with an output shaft (12) and a gearing comprising an output pinion (13) and a mating pinion (14), having a tool (16) mounted onto a tool shaft (16) coupled to the drive motor, and having a spindle arresting device (20, 21, 22, 25), which is operable by means of first and second operating means (23, 30) disposed a distance apart from one another and by means of which, particularly upon a change of tool, a rotation of the tool shaft (15) is prevented with the aid of a latching pin (22) which engages positively into the output spindle (12) and is displaceable against a spring (25), the first operating means (23) which is radially displaceable in the machine housing (11) relative to the tool shaft (15) being coupled by a substantially oblique-plane sliding ramp (28) to the second operating means (30) which is axially displaceable in the machine housing (11) relative to the tool shaft (15) and projects beyond the mounting surface (33), the object of providing a simply constructed, easy-to-manufacture spindle arresting device is achieved in that the latching pin (22) carries a leaf spring (25), which supports the latching pin counter to operating direction and on which the second operating element (30) is supported at right angles to the latching pin (22) in such a way that the second operating element by displacing the leaf spring (25) displaces the latching pin (22). <IMAGE>
