摘要： A motor-driven hand circular saw, has a base plate, a motor, a drive housing surrounding the motor, a saw blade provided with saw teeth and being in operative connection with the motor, a saw blade housing accommodating the saw blade, an upwardly movable saw shaft having the saw blade, a hinge arranged so that the drive housing together with saw blade is movable upwardly and downwardly normal to the saw shaft with respect to the base plate for cutting depth adjustment. The saw blade is movable in and out. A turning hinge having a turning axis extends in a feed direction so that the saw blade housing is connected through the turning hinge with the base plate, and there is at least one upper and lower handle with respect to the base plate. The saw blade housing with the saw blade is located at the left and the drive housing is located at the right as considered in the feed direction. The hinge for cutting depth adjustment is arranged at the front side of the base plate as considered in the feed direction. The upper handle is formed as a pistol-like handle having a free end extending parallel to the feed direction and toward the base plate downwardly.

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.
