Embodiment Construction

[0019] figure 1 The side view of a hand-held power tool 10 shown in shows a hand-held superfinishing machine whose housing 12 has in the upper region an elongated, rearward, ie, with a longitudinal axis 15 Directly pointing to the right, the cylindrical, rotatable main handle 14 is provided with a grinding disc 16 in the lower part for receiving a grinding disc 18 for grinding the surface of a workpiece. Centrally rearward from the main handle 14 is a cable 20 for powering the motor. Furthermore, a dust collection container 22 projects rearwardly from the lower rear housing region of the housing 12 for receiving grinding dust formed during work with the hand-held power tool. A nose-shaped region of the housing 12 serving as an auxiliary handle 13 protrudes forward.

[0020] The main handle 14 can be comfortably gripped by hand and can be pivoted about its longitudinal axis 15 from an initial rotational position into an end rotational position against the restoring force of s...

Abstract

The invention relates to a hand machine tool with a motor which is held in a housing (12) and a tool (16) which can be driven by the motor and has handles (13, 14) and a switch (17) for turning the motor on and off, and for setting different speeds thereof, can be handled in a more reliable, convenient and intuitive manner through the possibility of gradually switching the switch (17) by the handles (13, 14) which can be rotated from a starting position to an end position, in particular about its longitudinal axis (15).

Description

technical field [0001] The invention relates to a hand-held power tool with a motor accommodated in a housing, a tool driven by the motor, a handle and a device for switching on and off, in particular for setting different rotational speeds of the motor switch. Background technique [0002] Hand-held power tools are known which are provided with a slide switch for switching the motor on and off, which, depending on the actuated travel distance, causes the motor to be run gradually slower or faster. [0003] These known slide switches can only be actuated by pressing with a finger, so that in this case the actuating finger for the slide switch cannot grip the handle of the hand-held power tool with all its strength. Contents of the invention [0004] According to the invention, a hand-held electric power tool is proposed which has a motor received in a housing, a tool driven by the motor, a handle and a switch for switching the motor on and off and for A switch for adjust...
