Problems solved by technology

This makes it possible for the support device to have practically the same orientation as the saw blade in the swivel position, independently of the corresponding operating situation, so that it is hardly possible to change the supporting characteristics in different operating situations and also leads to a relatively complex construction

Embodiment Construction

[0019] figure 1 A hand-held machine (as an example of a power tool 1 ) in the form of a jigsaw 2 is shown, which has a housing 3 and is supported via a base plate 4 on a workpiece 5 .

[0020] In the front region of the jigsaw 2 in the working direction 6 , it has a saw blade 8 designed as a working tool 7 . During operation, this saw blade 8 acts on a workpiece 5 on which the jigsaw 2 is movably supported via the base plate 4 .

[0021] On the housing 3 of the jigsaw 2, in the vertical direction, on the opposite side of the base plate 4 (this base plate 4 can be fixedly supported around the pivot axis extending in the working direction 6) is provided with a handle 11, its handle 12 Extends toward the guide handle 14 . A switching device 15 is arranged below the handle 12 by means of which the jigsaw 2 is switched on and off. The different operating modes of the jigsaw 2 are adjusted via the switching device 16 arranged on the longitudinal side of the housing 3 . The end w...

Abstract

The invention relates to a power tool (1) which is designed as a jigsaw (2) and which comprises a rear support (20) for the saw blade (8) at a right angle to the rotational axis (22) of the saw blade (8). Said support (20) is designed as an element that is carried along by the saw blade in the rotational direction.

Description

technical field [0001] The invention relates to a power tool according to the preamble of claim 1 , in particular a hand-held power tool. Background technique [0002] A machine tool of the aforementioned type is known from EP 1 598 136 B1 and is in the form of a jigsaw in which the saw blade is driven reciprocatingly and only in normal operation when reciprocatingly driven. If this reciprocating drive is superimposed by a pivoting movement about a pivoting axis transverse to the plane of the saw blade, the jigsaw operates in the pendulum-reciprocating mode. Another mode of operation occurs if the jigsaw is driven as a so-called scrolling jigsaw. Then, in addition to the reciprocating drive of the saw blade, there is also a rotatability about the axis of rotation (which extends in the longitudinal direction of the saw blade), so that the corresponding working direction can basically be adjusted by rotating the saw blade. [0003] In all modes of operation, the saw blade is...
