Abstract: An assembly includes a mowing head (3), an output shaft (8), and a fastening device (10). The output shaft (8) is drivable in rotation about an axis of rotation (9). The assembly (2) has an anti-rotation lock (11) and an axial lock (16). The mowing head (3) is held corotatingly on the output shaft (8) by the anti-rotation lock (11). The axial lock (16) locks the mowing head (3) in a blocking position (30) of the output shaft (8) against a relative movement in the direction of the axis of rotation (9) of the output shaft (8) and in an inoperative position (31) releases the mowing head (3) for detachment from the output shaft (8). The fastening device (10) includes an actuating element (24) accessible to the operator. The axial lock (16) is switchable into the blocking position (30) and into the inoperative position (31) by the actuating element (24).

Abstract: A carrying device for carrying a hand-guided power tool by a user has a shoulder strap and a lateral leg plate with a connecting unit for coupling a power tool to the carrying device. A support strap is connected with one end to the shoulder strap and the leg plate is slidably arranged at the support strap to slide along the support strap in a longitudinal direction thereof. A fixation device is arranged between support strap and leg plate and has a release position and a blocking position. In the release position, the leg plate is slidable along the support strap; in the blocking position, the leg plate is non-slidably secured on the support strap. The blocking position is correlated with a first working mode of the power tool; the release position is correlated with a second working mode of the power tool.

Abstract: A clamp for fastening an elongated element to a carrier has a first receiving region for the carrier and a second receiving region for the elongated element. The clamp has a peripheral wall defining first and second end faces. The first receiving region is delimited by a first wall section of the peripheral wall, and the second receiving region is delimited by a second wall section of the peripheral wall. The first wall section and the second wall section are mutually contiguous at two connecting locations. The first and second receiving regions between the connecting locations are mutually connected and conjointly form a single receiving space. The peripheral wall in the closed state of the clamp extends in a fully encircling manner about the receiving space. One of the wall sections has two partial wall sections and the respective ends thereof form a closure for releasably connecting the partial wall sections.
