Abstract

The disclosure relates to a portable machine tool, in particular a hand-held machine tool, comprising at least one coupling device which is designed to be coupled to a machine tool separation device having at least one cutting unit and at least one guide unit for guiding the cutting unit. According to the disclosure, the portable machine tool comprises at least one machine tool stabilizing device which comprises, in an area outside the coupling device, at least one stabilizing element having at least one support surface for stabilizing the machine tool separation device.

First claim

The invention claimed is:

1. A hand-held power tool, comprising:
a housing defining a recess;
a drive unit supported by the housing;
a power-tool parting device extending from the housing and including at least one cutting strand and at least one guide unit configured to guide the at least one cutting strand;
at least one coupling device configured to operatively connect the power-tool parting device to the drive unit, such that the drive unit is configured to move the at least one cutting strand relative to the at least one guide unit; and
at least one power-tool stabilization device including at least one stabilization element having a guide element slidably received within the recess defined by the housing and at least one support face extending from the guide element and configured to stabilize the power-tool parting device.

2. The hand-held power tool as claimed in claim 1 , wherein:
the at least one power-tool stabilization device includes at least one further stabilization element having a guide element slidably received within another recess defined in the housing, the at least one further stabilization element including at least one further support face which, together with the at least one stabilization element, delimits a stabilization region of the at least one guide unit.

3. The hand-held power tool as claimed in claim 1 , further comprising:
at least one seating unit mounted on the housing and configured to seat on a workpiece.

4. The hand-held power tool as claimed in claim 1 , further comprising:
at least one spring element located in the recess and configured to exert a spring force upon the at least one stabilization element.

5. A hand-held power tool, comprising:
a power-tool parting device that includes at least one cutting strand and at least one guide unit configured to guide the at least one cutting strand;
at least one coupling device configured to couple to the power-tool parting device;
at least one a power-tool stabilization device, which, in a region disposed outside of the at least one coupling device, includes at least one stabilization element that has at least one support face configured to stabilize the power-tool parting device; and
at least one seating unit configured to seat on a workpiece,
wherein at least one of the stabilization element and a further stabilization element includes an extent that, as viewed along a line that is at least substantially perpendicular to a seating face of the seating unit, closes in an at least substantially flush manner with the seating face.

6. The power-tool system as claimed in claim 5 , further comprising:
a housing defining a recess,
wherein the power-tool parting device extends from the housing,
wherein the at least one stabilization element includes a guide element slidably received within the recess defined by the housing, such that the at least one stabilization element is movably mounted on the housing.

7. The power-tool system as claimed in claim 5 , further comprising:
a housing from which the parting device extends,
wherein the at least one stabilization element is integral with the housing.
