    摘要: An electric hand saw has a stationary sword having a lower side, a reciprocatable saw blade received in the lower side of the sword and having a rear end portion, a machine housing having a transmission outlet in which the rear end portion of the saw blade is received. The machine housing has a longitudinal slot located under the rear end portion of the saw blade. A suction passage is mounted on the lower side of the machine housing and has a sucking-in opening extending from the front end side of the suction passage to the longitudinal slot of the machine housing located under the rear end portion of the saw blade.

    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.
