A rotatingly drivable filament cutting head for a trimmer, having a basic body on which a cutting filament is held. The cutting filament extends from outside the basic body through an opening into an interior region of the filament cutting head open to the surrounding area. A stop is arranged on the filament cutting head, so that, in a first position of the cutting filament, the stop delimits a filament portion of the cutting filament, which is insertable into the interior region, to an insertion length. A deflection element is arranged in the interior region so that the cutting filament can be switched from its first position, without the cutting filament being longitudinally displaced, into a second position. The cutting filament abuts against the deflection element in its second position and the stop does not delimit the length of the filament portion which is insertable into the interior region.

Filament cutting head for a trimmer

A filament cutterhead is provided for mounting on the drive shaft of a brushcutter. The filament cutterhead includes a housing with a circumferential wall wherein a first wall opening for a cutting filament is formed. A filament spool arranged in the housing is rotatable relative to the housing. A filament channel with a filament inlet segment is provided in a partition wall of the filament spool. The filament channel extends from the filament inlet segment past the hub to a filament outlet segment which is assigned a second wall opening in the circumferential wall. The filament outlet segment is at an offset (v) with respect to the filament inlet segment in the circumferential direction of the hub. The mouth of the filament inlet segment and the mouth of the filament outlet segment lie within an outside diameter (A) of the partition wall and open into a pass-through space.
