For a machine tool designed in particular as a saber saw, a configuration including a carrying frame is provided, via which the lifting rod and the support element are joined to form a unit that can be rotated about the longitudinal axis of the power tool, is mounted on the casing side, and guides a drive part of the lift drive on the lifting rod side.

Motor-driven machine tool

A hand-held jigsaw includes a saw blade and control element for automating a tracking the saw blade, the hand-held jigsaw, or both along layout lines. A sensor, preferably a camera unit, detects a layout line provided on a work piece.

Hand-held jigsaw

A handheld jigsaw, such as a compass saw (), is disclosed that comprises a housing () and a lifting rod () having a pendulum mechanism (). The pendulum mechanism includes a pendulum lever () with which a pendulum stroke can be given during sawing to a saw blade () carried by the lifting rod (). The lifting rod () is arranged such that it can rotate about its own axis () thereof and pivot transversely to the axis (), and wherein the pendulum mechanism () can rotate about the axis ().

Hand-held power jigsaw

A handheld power tool having a power tool that executes a reciprocating motion, in particular a reciprocating power saw with a reciprocating sawblade (), is disclosed. To prevent the power tool from sawing untrue during the cutting operation, in particular between the upper and lower cutting edges, the power tool is assigned at least one force transducer (), which measures the magnitude of a transverse force, oriented transversely to the direction of motion, that occurs at the power tool, and at least one actuator (), which acts on the power tool as a function of the measured magnitude of the transverse force, is provided for transverse force compensation (FIG.).

Handheld power tool

The invention relates to a clamping device () for connecting a saw blade () to a reciprocating rod () of a jig saw, in particular a hand-operated compass saw (), comprising a mounting (), which is connected to the reciprocating rod () and has a recess () for receiving a head end () of the saw blade (), a locking sleeve (), which can be turned about the axis () with respect to the mounting () against the force of a torsion spring () to lock the head end () of the saw blade () in a locking position in the recess () and to allow removal of the saw blade () in a removal position. It is intended that a stop () interacts with a part () of the torsion spring (), in order to prevent movement of the locking sleeve () beyond the removal position.

Clamping device for a jigsaw

A handheld power tool includes a housing () and a foot plate () for guidance on a surface of a workpiece. A pump unit (), preferably located in the foot plate (), drives a coolant and/or lubricant flow () for cooling and/or lubricating at least one heavy-duty component ().

A power compass saw with a housing that accommodates a lifting rod for the up and down movement of a longitudinal saw blade attached thereto, has a toothed side and a saw blade back and with a guide roller which supports the saw blade back and has a central groove into which the saw blade extends with its saw blade back and is guided therein, the central circumferential groove has tapered groove sides with a 5&#xb0; taper, the saw blade back has a straight portion and an end beveled portion with beveled edges having a 7&#xb0; taper at both sides, the saw blade back has diametrically opposed edges provided at a transition from the straight portion to the beveled portion, and the saw blade back has a width which is measured between the diametrically opposed edges and is greater than a width of a bottom of the circumferential groove.

A tool fastening mechanism has a housing , in which a clamping opening is embodied for receiving a tapering tool shaft clamping end of a tool part . The clamping opening tapers inward in the introduction direction of the clamping end of a tool part , and furthermore the tapering sides are inclined toward one another in a plane extending perpendicular to the introduction direction, as a result of which the opening has a trapezoidal cross section, and the length of this cross section decreases away from the orifice of the clamping opening . The housing furthermore has a transverse opening , which intersects the clamping opening and in which a locking pin is received. Upon introduction of a tool into the fastening mechanism, a tapering edge of the pin comes into engagement with a front edge of an oblong hole , embodied in the clamping edge of the tool part , and the resultant engagement action draws the clamping end deeper into the clamping opening , while the pin is driven farther into the transverse opening . The combination of the double tapering of the clamping opening and the longitudinal locking accomplished by the locking pin makes it possible to effectively restrict all six degrees of freedom of the tool part, within the production tolerances attainable by conventional mass-production methods.

Detachable tool fixing mechanism and tool for use therewith

A swinging saw has a saw blade performing a working movement with a superimposed swinging movement, a displacement rod supporting the saw blade and performing a swinging movement, a displacement rod support having an opening opening through which the displacement rod is guided. The displacement rod is guided such that relative movement, or play, is provided between the guide and the displacement rod in the swinging plane while play is prevented in a plane transverse to the swinging plane.
