Embodiment Construction

[0042] figure 1 A hand-held power tool 10 is shown, for example, in the form of a router 12 , which illustratively has a machine housing 14 , a mains switch 16 and a mains feeder 20 . However, it should be pointed out that the invention is not limited to grid-operable routers 12, but is more applicable to grid-operable routers or hand-held power tools that can be connected to An associated accumulator is mechanically and electrically connected for power supply or has an alternative pneumatic drive.

[0043] By means of the drive motor 22 , an insert tool 26 of the router 12 , which is designed here only by way of example as a milling tool 24 , can be driven at a high rotational speed. For precise, plane-parallel guidance of the router 12 on the workpiece 28 , the router has a support device 30 having an at least substantially hollow-cylindrical support element 32 for receiving the machine housing 14 at least in sections. The support device 30 is preferably made of a sufficie...

Abstract

The power tool (10) has a clamping device (42) that is arranged for tightening a hollow cylindrical carrier element (32) at machine housing (14) in the region of longitudinal slot (44). A rotatable adjusting shaft (64) of height adjustment device (62) is provided in the region of clamping device, in order to set a working height (70) of power tool by a displacement of power tool in hollow cylindrical carrier element along a longitudinal axis (16). The rotational axis (72) of adjusting shaft is extended in parallel to longitudinal axis or approaching vertically to longitudinal axis.

Description

technical field [0001] The invention relates to a hand-held power tool, in particular a router, with a machine housing and a support device, the machine housing having an associated longitudinal axis for plane-parallel guidance of the hand-held power tool on a workpiece , wherein the supporting device has a substantially hollow-cylindrical carrying element for at least sectionally accommodating the machine housing, the carrying element has a longitudinal slot and a bottom plate arranged at a predetermined angle at the axial end facing the workpiece, The base plate has a recess for inserting a tool, in particular a milling tool, wherein a clamping device for clamping the hollow cylindrical support element to the machine housing is provided in the region of the longitudinal slot. Background technique [0002] From DE102004033801A1, a hand-held power tool constructed in the manner of such a milling machine with a support device is disclosed, the hand-held power tool has a hollo...
