Abstract: A trimmer line cutting head has a trimmer line spool rotatably supported about an axis of rotation and disposed slidably between housing and housing cover along the axis of rotation. A spring element pretensions the trimmer line spool in an operating position of the trimmer line cutting head. An indexing device has a terminal stop connecting the trimmer line spool in the operating position to the housing in fixed connection for common rotation of trimmer line spool and housing. By applying an actuating force to the indexing device, the trimmer line spool is adjustable from the operating position axially into an inoperative state of the trimmer line cutting head for paying out trimmer line. The indexing device has a rotational stop formed in a slot in a wall of the trimmer line spool and limiting rotation of the trimmer line spool relative to the housing in the inoperative state.

Abstract: A cutter head for a brush cutter has a base body with top base body part and bottom base body part. A screw element is arranged at the bottom base body part for attachment to an output shaft of the brush cutter. A receptacle for fastening a cutting tool is provided between top and bottom base body parts. The base body is rotatably driven in operation of the brush cutter about an axis of rotation of the base body. The top and bottom base body parts are held together by a detachable snap-on connection. The snap-on connection is positioned at a distance, measured in a radial direction, from the axis of rotation of the base body. The distance amounts to at most 40% of the cutter head diameter. For releasing the snap-on connection, the top and bottom base body parts are pulled apart from each other by a pulling force.

Abstract: A mowing head for a trimmer is rotated about an axis of rotation when operated and has a housing with a circumferential wall. A fastening device with a trimmer line guide with a trimmer line channel is provided for the trimmer line. The trimmer line channel has a clamping section with a longitudinal direction. The clamping section has a wide longitudinal side and a narrow longitudinal side, both extending in the longitudinal direction. The clamping section has an inner width tapering from the wide longitudinal side toward the narrow longitudinal side. The trimmer line guide has a deflection edge adjoining the clamping section. The deflection edge is slanted relative to the longitudinal direction such that the deflection edge generates a force component acting on the trimmer line directed toward the narrow longitudinal side when a pulling force is acting on the trimmer line guided through the fastening device.

Abstract: A device for fastening a tool member on an output shaft of a power tool has a support plate supporting the tool member and a clamping element embodied as a connecting hub. The connecting hub is penetrated by the output shaft and is rotationally fixed on the output shaft. A rider plate is secured on the connecting hub and rotatable relative to the connecting hub. Support plate, tool member, rider plate, and connecting hub are arranged such that the output shaft projects through support plate, tool member, rider plate, and connecting hub. A clamping device is carried on an end of the output shaft. The clamping device acts on a support surface of the connecting hub and fixes through the connecting hub the tool member on the support plate. Connecting hub, rider plate, and pressure plate together form preferably a conjoint, connected component assembly.
