Embodiment Construction

[0018] The side view of a hand-held machine tool 10 shown in FIG. 1 reflects a hand-held superfinishing machine whose housing 12 has a longitudinal axis 15 in the upper region, which is elongated, that is rearwardly A cylindrical, rotatable main handle 14 pointing to the right in the viewing direction is provided with a grinding disc 16 at the lower part for receiving a grinding sheet 18 for grinding the surface of a workpiece. A cable 20 for powering the motor is led out from the main handle 14 in the center and rearward. In addition, a dust collecting container 22 protrudes backwards from the lower rear housing area of ​​the housing 12 for receiving grinding dust formed when the hand-held power tool is used. A nose-shaped area of ​​the housing 12 used as an auxiliary handle 13 extends forward.

[0019] The main handle 14 can be comfortably held by hand and can rotate about its longitudinal axis 15 against the restoring force of an unshown elastic device from an initial position ...

Abstract

The invention relates to a hand-held power tool with a motor accommodated in a housing (12), a tool (16) driven by the motor, handles (13, 14) and a tool for switching on and off , especially a switch (17) for adjusting different motor speeds. For reliable, comfortable and intuitive operation, the invention proposes that the switch (17) can be gradually adjusted by a handle (13, 14), in particular pivotable about its longitudinal axis (15) from an initial position to an end position.

Description

Technical field [0001] The invention relates to a hand-held power tool, which has a motor received in a housing, a tool driven by the motor, a handle, and a handle for switching on and off, especially for adjusting different motor speeds Switch. Background technique [0002] A hand-held power tool equipped with a sliding switch for turning on and off the motor has been disclosed, and the sliding switch can make the motor gradually slow down or run faster depending on the movement displacement that is operated. [0003] These known sliding switches can only be operated by pressing with fingers, so that in this case, the operating fingers for the sliding switch cannot hold the handle of the hand-held power tool with full force. Summary of the invention [0004] According to the present invention, a hand-held power tool is proposed, which has a motor received in a housing, a tool driven by the motor, a handle, and a handle for switching on and off, in particular for adjusting A swi...
