    摘要: A handheld machine tool, for example a circular saw, has a disk-shaped tool which is driven in rotation in a housing which holds a drive motor and a tool shaft carrying the tool. The tool can be clamped between a clamping nut, a clamping screw, and two supporting flanges. One supporting flange can be rotated easily relative to the tool shaft without use of auxiliary tools and is supported with an extensive friction at the tool. This supporting flange can be dependably clamped or loosened without tools. The machine tool further has an adjusting device which is coupled with that supporting flange to displace the latter axially toward the tool when that supporting shaft is rotated relative to the tool shaft due to rotational driving. The adjusting device therefore clamps the tool with an increasing force and tries to displace that supporting flange axially away from the tool automatically when the tool is stopped and accordingly reduces the clamping force.

    摘要: The hand-held machine tool has a tool holder (20) provided with a receptacle (19) into which a shaft portion (15) of a tool (16) is axially insertable. The tool holder (20) has a longitudinal axis (11) and includes a guide device (18) for axially guiding the tool (16); a device (23) for rotary slaving of the tool (16); a retaining device (28) for axially securing the tool (16) and a locking member (34) for locking the retaining device (28) in an open configuration for insertion or removal of the tool (16). The retaining device (28) is located in front of the guide device in an insertion direction of the tool (16) in the tool holder (16). The retaining device (28) is provided with an opening (31) for passage of the tool (16) through it. The retaining device (28) includes a clamping part (30) having an open position arranged approximately perpendicular to the longitudinal axis (11) and is pivotable out of the open position in a direction toward the longitudinal axis (11) to reduce an effective cross-section of the opening (31) and into a clamping position in which the clamping part (30) and the tool (16) are clamped together.
