    摘要： The invention relates to a hand-guided electric tool (3) comprising a housing (2) on which a locating collar (20) is provided, and comprising a guard (1), which can be attached to the locating collar (20) and which has a tightening band (16) that, when in a first position, can be freely displaced around the locating collar (20) and, when in a second position, rests in a fixed manner against the locating collar (20). The aim of the invention is to obtain a secure connection between the guard (1) and the housing (2). To this end, the locating collar (20) has at least one shaped element (21) that projects over the second surface in a radial direction from the spindle arbor (5) while pointing away therefrom. A distance (h) exists between the shaped element (21) and the housing (2) and approximately corresponds to the width (b) of the tightening band (16). In addition, the tightening band (16) has at least one bulge (12) so that the first diameter (d1) of the opening (10) of the tightening band (16) is larger in the area of the bulge (12) than the second diameter (d2) in the remaining area. The first diameter (d1) is provided with a dimension that enables the tightening band (16) to move over the shaped element (21), and the second diameter d2 is provided with a dimension that prevents the tightening band (16) from moving over the shaped element (21).

    摘要： The invention relates to a hand machine tool comprising two cutting disks (11, 12), which rotate counter and immediately adjacent to one another and which can be driven by two drive spindles (14, 15) that are arranged concentric to one another. The hand machine tool also comprises a tool holding fixture (13) for the cutting disks (11, 12) that has a seating flange (18, 24), which is joined in a rotationally fixed manner to the inner and outer drive spindle and which is provided for the centered seating and the positive rotational engagement of the cutting disks (11, 12). The hand machine tool additionally has chucking means for ensuring the positive engagement between the cutting disks (11, 12) and the seating flanges (18, 24). The aim of the invention is to obtain a simple design of the tool holding fixture (13) having a high level of functional safety and a small space requirement as well as to enable the cutting disks to be changed without requiring the use of tools. To these ends, the chucking means comprise a screw part (27), which receives the second seating flange (24) and which, without the use of tools, can be screwed, on the face, into the inner drive spindle (15). In addition, the chucking means comprise a clamping part (28), which can be actuated without the use of tools, which axially presses the second seating flange (24) against the inner drive spindle (15) and which tightens the second seating flange (24) against the screw part (27).

    摘要： A hand power tool (10) with an oblong motor housing (16), particularly used as a handle, housing an electric collector motor (50), wherein the brushes (39) are housed in a brush holder (28) with a brush shaft (38) in a spring loaded way, said brush holder being solely/individually fixed in the motor housing (16), to which an axis intersection is associated, particularly a longitudinal (18), a vertical (20) and a transversal axis (22), said hand power tool being arranged in the motor housing (16) in a space-saving manner in such a way that the shaft (38) of the brush holder (28) is arranged opposite the vertical axis (20) of the motor housing (16) at an angle of approximately 20° in a laterally displaced way, particularly radially, relative to the longitudinal axis (18).
