Embodiment Construction

[0028] figure 1 A hand-held power tool 100 , which is designed by way of example as a circular saw, 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 arranged in the housing 110 at least in sections. 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 ) is designed in particular to drive the replaceable saw blade 130 in rotation about the associated axis of rotation 142 . The saw blade 130 is preferably configured as a circular saw blade with a blade 132 .

[0029] Preferably, the circular saw 100 is mechanically and electrically connected to the wires 107 for a grid-dependent supply of current, but alternatively or additionally, a battery pack may be provided for a grid-independent supply of current. In the figures, the circular saw 100 is constructed i...

Abstract

A circular saw (100), in particular a hand-held circular saw, has a housing (110) and a drive unit arranged at least in sections in the housing (110), the drive unit being assigned to a replaceable saw blade ( 130 ) of the tool receiver ( 140 ), wherein the drive unit ( 710 ) is designed to drive the replaceable saw blade ( 130 ) in rotation about the associated axis of rotation ( 142 ), wherein the replaceable saw blade ( 130 ) A protective wedge (150) is provided, which is mounted in the housing (110) rotatably about an associated axis of rotation (142) and holds the blade (132) of the replaceable saw blade (130) at least during the sawing process During this period, it is surrounded so that the blade (132) is at least substantially prevented from being touched.

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 a replaceable saw blade, wherein the drive The unit is designed to drive the replaceable saw blade in rotation about the associated axis of rotation. Background technique [0002] Such circular saws, which are designed as hand-held circular saws, have a housing and a drive unit arranged in sections in the housing are known from the prior art. 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 an oscillating guard. The pivotable guard surrounds the saw blade and is mounted...
