Embodiment Construction

[0033] exist figure 1 The exemplary hand-held power tool 10 shown schematically in has an elongated housing 12 with a longitudinal axis 13, which carries on its upper side a device for switching on and off located in the housing 12. The switch button 14 of the not shown motor. The motor is connected via a cable 16 to a power supply or is fed directly from a storage battery. The motor transmits its motion to a driven shaft 18 with axis 20 , which is mounted at the front of the housing 12 . The axis 20 protrudes from the housing 12 at an angle, essentially at right angles, to the longitudinal axis 13 in this example and carries an inner flange 24 at its end, which simultaneously serves as the driver 19 .

[0034] The driven shaft 18 carries on its inner flange 24 a releasably clampable, oscillatingly drivable, substantially flat tool 22 which is configured as a flat, circular segment-shaped saw blade 22a and can be A fastening device in the form of a clamping screw 27 is cla...

Abstract

The invention relates to a stop device, particularly a depth stop (280), for a rotationally driven, particularly oscillatingly driven, chipping or cutting, round and / or angular disc shaped tool (22, 220) of a portable machine tool, particularly a saw blade, by means of which a cut (92) can be produced in a workpiece (90) in a chipping manner, comprising a disc-like means that is arranged axially adjacent to the tool (22, 220), preferably axially supported thereon, and exposes opposite the outer edge thereof (290) a certain part of the tool (22) for penetration into the cut (92) by a defined degree and prevents further penetration into the cut (92) beyond the defined degree, as soon as the edge (290) is supported on the tool (90). According to the invention, the disc-shaped tool (22, 220) is crucible-shaped and the stop device, particularly the depth stop (280), is also similarly designed so as to be precisely crucible-shaped, wherein the depth stop (280) enters a concave crucible-shaped region of the tool (22, 220) and / or vice versa, it receives the tool (22, 220) in an axially supporting manner in the concave crucible-shaped region thereof.

Description

technical field [0001] The invention relates to a stop device, in particular a depth stop, for a tool of a hand-held power tool according to the preamble of claim 1 or claim 9 and a hand-held power tool, in particular Hand-held machine tool with oscillating drive shaft. Background technique [0002] Hand-held power tools of this type are known to have a rotating, in particular oscillatingly driven, cutting or cutting, round and / or angular disk-shaped tool, in particular a saw blade, by means of which the workpiece can be cut The kerf is produced in a medium-cut manner, wherein the tool can be coupled with its radially inner region to the inner flange of the driven shaft as a driver, wherein the radially inner region of the tool has a plurality of The driving openings or recesses on the top serve as cooperating means for a form-fitting, play-free fit into a plurality of mandrel-shaped projections arranged on the same pitch circle of the driver. [0003] This driver system o...
