Embodiment Construction

[0029] figure 1 An exemplary hand-held power tool 100 in the form of a circular saw is shown, which has a housing 110 which preferably forms a handle 112 . The circular saw 100 is preferably equipped with a drive unit ( Figure 7 710 in ), the drive unit is at least partially arranged in the housing 110 . Preferably, the drive unit ( Figure 7 710 in ) is used to drive the tool receiver 140 for the replaceable saw blade 130 . Here, the drive unit ( Figure 7 710) in particular is designed to drive the replaceable saw blade 130 in rotation about the associated axis of rotation 142 . The saw blade 130 is preferably designed as a circular saw blade with an edge 132 .

[0030] Preferably, the circular saw 100 is mechanically and electrically connected to the electrical line 107 for a grid-dependent supply of current, but alternatively or additionally a battery pack can be provided for a grid-independent supply of current. In the figures, the circular saw 100 is configured as...

Abstract

The invention relates to a circular saw (100), in particular a hand-held circular saw, having a housing (110) and a drive unit, at least some sections of which are arranged in the housing (110) and with which a tool holder (140) for an exchangeable saw blade (130) is associated, the drive unit (710) being designed to rotationally drive the exchangeable saw blade (130) about an associated axis of rotation (140). In said circular saw a blade guard (150) is associated with the exchangeable saw blade (130), which blade guard is mounted in the housing (110) for rotation about the associated axis ofrotation (140) and which extends around a cutting point (132) of the exchangeable saw blade (130) at least during a sawing operation in such a way that contact with the cutting point (132) can be atleast substantially prevented.

Description

technical field [0001] The invention relates to a circular saw, in particular a hand-held circular saw, with a housing and a drive unit arranged at least in sections in the housing, the drive unit being equipped with a tool receptacle for an exchangeable saw blade, wherein the drive The unit is designed to drive the replaceable saw blade in rotation about an associated axis of rotation. Background technique [0002] Circular saws of this type which are designed as hand-held circular saws are known in the prior art, which have a housing and a drive unit arranged in sections in the housing. In this case, the drive unit is provided with a tool receptacle for the replaceable saw blade, and the drive unit is designed to drive the replaceable saw blade in rotation about an associated axis of rotation. In order to protect the user of the circular saw from being injured by touching the blade, the circular saw has a swing-out guard. The pivot guard surrounds the saw blade and is mo...
