Abstract
A portable trimmer has a supporting tube with a forward end on which is mounted a cutting device. The cutting device has a case with a first hole for receiving a stick, and also contains a rotatable shaft with a threaded end. A seating member that is rotatable with the shaft has a second hole that can be aligned with the case's first hole. A rotatable cutter is removably mounted on the rotatable shaft, fixed to against the seating member by a nut that engages the shaft's threads. The stick is inserted into the first hole in the case and the second hole in the rotatable seating member, to prevent rotation of the seating member during assembly and disassembly. The cutting device retains the stick in the first and second holes even when the cutting device is upside down. This retention is accomplished, either by a biasing member that biases the stick in a direction perpendicular to the axis of the first hole, or by an elastic member that frictionally engages the stick in the hole.
