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 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

The invention relates to a guide device () for a saw blade (), in particular for an electric tool, which is operated in reciprocating motion (H) and which comprises a clamping device () engaging in the clamping end () of the saw blade (), and a pendulum guide device () attached to the back of the saw blade and located at an axial distance (a) from the clamping device (). According to the invention, the pendulum guide device () features at least two guide elements () which are arranged at an axial distance from each other. The invention further relates to an electric tool which features said guide device (). Moreover, the invention relates to an electric tool with said guide device (), in particular a jigsaw ().

Guide device for a saw blade that executes lifting motions

A pendulum guide device for a power jigsaw saw blade that executes reciprocating motions includes guide elements that engage a saw blade spine of the saw blade and are associated with a support frame. A first two guide elements is fixed in place on the support frame and a second guide element is bearing-mounted to the support frame in moving fashion and is prestressed in the direction toward the saw blade spine.

Pendulum guide device for a jigsaw blade that executes reciprocating motions

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.
