Title: POWER-TOOL CUTTING DEVICE
Abstract:
The invention is based on a power-tool cutting device with at least one cutting strand (12a; 12b; 12c; 12d), with at least one guide unit (14a; 14b; 14c; 14d) for guiding the cutting strand (12a; 12b; 12c; 12d), which guide unit in particular together with the cutting strand (12a; 12b; 12c; 12d) forms a closed system, and with at least one deflecting unit (18a; 18b; 18c; 18d) which is arranged on a drive-remote side (16a; 16b; 16c; 16d) of the guide unit (14a; 14b; 14c; 14d) and has at least one movably mounted deflecting element (20a; 20b; 20c; 20d) for deflection of the cutting strand (12a; 12b; 12c; 12d) at least while the cutting strand (12a; 12b; 12c; 12d) revolves about the guide unit (14a; 14b; 14c; 14d), said deflecting element comprising at least one contact surface (22a; 22b; 22c; 22d) for an at least temporary contact with the cutting strand (12a; 12b; 12c; 12d). It is proposed that the deflecting element (20a; 20b; 20c; 20d) is designed to be at least substantially free from an extension for engagement in the cutting strand (12a; 12b; 12c; 12d).
