摘要:
A cutting apparatus of a type where two juxtaposed blades are caused to move through sequential approximately elliptical paths and having teeth at respective outer edges of the two juxtaposed blades the relatively moving teeth on the edge of the respective blades being adapted to be urged against a surface to b cut, and at least one anchoring locator which is positioned beyond a periphery of the respective blades and thereby adapted to engage with a work piece while it is being cut and provide thereby a potential anchoring position for a work piece.

An especially hand-held machine tool, preferably designed as a jigsaw (2), comprises a distance measuring unit (29) for the contactless detection of a section (43) of a specified path and for visualizing a working path (33) corresponding to the specified path (31) and/or for aligning the machine tool (1) including its working tool (7) with the working path (33) corresponding to the shape of the specified path (31) by means of an adjusting device.

The invention relates to a motor-driven pendulum saw (10) that can be used as a stationary machine for precise severing or mitre cuts, while preserving its properties as an autonomous hand-held tool due to the fact that it can be detachably connected to a cutting table (11, 61) on which the pendulum saw can be adjusted to saw a workpiece and the relative position between the workpiece and the saw blade (13) of the pendulum saw (10) can be adjusted.

A power tool includes a motor housing having a motor configured to rotate an output shaft about a drive axis and a gear housing defining a gear compartment. A pinion gear is supported by the gear housing that is coupled to the output shaft for rotation about the drive axis. A bevel gear is supported by the gear housing for rotation about a bevel axis perpendicular to the drive axis, the bevel gear being meshingly engaged with the pinion gear. A crank pin extends from the bevel gear at a position offset from the bevel axis. An articulating housing is pivotably supported by the gear housing for pivotal movement about the bevel axis. A plunger member is supported by the articulating housing for reciprocating movement along a reciprocating axis. The plunger member includes a yoke end portion coupled to the crank pin. The reciprocating axis and the drive axis reside in the same plane throughout pivotal movement of the articulating housing with respect to the gear housing.

The invention relates to a stationary, motor-driven underfloor saw (1), which is designed as a keyhole saw and can be displaced in the direction of the saw blade plane along the bench surface (13) as a trim saw. With respect to the position of the saw blade plane, said saw can be pivoted in relation to the bench (3) about an axis (50) that runs parallel to the intersection of the bench surface (13) and the saw blade plane.
