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.
