Abstract
A power-tool cutting device includes at least one cutting strand, at least one guide unit configured to guide the cutting strand, and at least one deflecting unit. The guide unit together with the cutting strand forms a closed system. The deflecting unit is arranged on a drive-remote side of the guide unit and has at least one movably mounted deflecting element configured to deflect the cutting strand at least while the cutting strand revolves about the guide unit. The deflecting element includes at least one contact surface for an at least temporary contact with the cutting strand. The deflecting element is configured to be at least substantially free from an extension for engagement in the cutting strand.
Claims10
A power-tool cutting device, comprising:
- at least one cutting strand;
- at least one guide unit configured to guide the cutting strand, the guide unit together with the cutting strand forming a closed system;
- and
- at least one deflection unit arranged on a drive-remote side of the guide unit, the deflection unit including at least one movably mounted deflection element configured to deflect the cutting strand at least during rotation of the cutting strand around the guide unit,
- wherein the deflection element includes at least one contact surface configured to at least temporarily contact the cutting strand, the deflection element realized at least substantially free of a continuation for engagement in the cutting strand.
A power tool system, comprising:
- at least one power-tool cutting device including:
- at least one cutting strand,
- at least one guide unit configured to guide the cutting strand, the guide unit together with the cutting strand forming a closed system, and
- at least one deflection unit arranged on a drive-remote side of the guide unit, the deflection unit including at least one movably mounted deflection element configured to deflect the cutting strand at least during rotation of the cutting strand around the guide unit,
- wherein the deflection element includes at least one contact surface configured to at least temporarily contact the cutting strand, the deflection element realized at least substantially free of a continuation for engagement in the cutting strand;
- and
- at least one portable power tool which comprises at least one coupling device for one or more of positive locking and friction locking coupling with the power-tool cutting device.
