Embodiment Construction

[0022] In the drawings, the same components and components having the same function are indicated by the same reference numerals.

[0023] The hand planer 1 shown in FIG. 1 has a plastic housing 2 . Electric energy is supplied to the hand-held planer 1 via the cable 3 . Inside the housing 2 there is a drive motor, not shown, for the planer shaft, not shown. The waste heat of the electric motor is discharged from the housing 2 through the lateral ventilation slots 4 . The hand planer 1 has a handle 5 with a switch button 6 for switching the electric motor on and off. In the front region of the hand planer 1 there is a rotary handle adjustment device 7 with a handle part 8 . The rotary handle adjusting device 7 serves on the one hand as an additional handle for handling the hand-held planer 1 and on the other hand for adjusting the cutting depth, ie the position of the planer shaft, not shown.

Abstract

The invention relates to a hand-held power tool (1), in particular a hand-held planer, having a rotary handle adjustment device (7) with a handle part (8), wherein the rotary handle adjustment device (7) can be adjusted at least in Between two adjustment positions spaced apart in the circumferential direction, according to the invention, means ( 11 , 15 , 20 ) are provided for preventing accidental twisting of the rotary handle adjustment device ( 7 ).

Description

technical field [0001] The invention relates to a hand-held power tool with a rotary handle adjustment device. Background technique [0002] Such hand-held power tools are known in various embodiments. What all known hand-held power tools have in common is that their rotary handle adjustment device is used as a handle on the one hand to withstand the handling force and grip force when operating the hand-held power tool, and on the other hand as an adjustment device, for example for changing the handle operating states of hand-held power tools or for adjusting the position of, in particular, rotating tools of hand-held power tools. [0003] A hand planer with a rotary handle adjustment is known from DE 102 25 622 A1. Such a rotary handle adjustment device has the function, on the one hand, of an additional handle for operating the hand-held planer and, on the other hand, the function of an adjustment device for changing the cutting depth of the hand-held planer. Users some...
