Abstract
A portable powered cutter comprises an operation tube (10), a transmission shaft (40) inserted through the operation tube (10), and a rotary blade (31) supported by a blade holder (30) connected to a forward end of the operation tube (10). The rotary blade (31) is rotated by rotational output of a power source transmitted by the transmission shaft (40). The blade holder (30) pivots, against a predetermined resistance, about a transverse axis (14) perpendicular to an axis of the operation tube (10) as viewed in plane. The transmission shaft (40) is flexible at least at a portion between the forward end of the operation tube (10) and the blade holder (30), and the flexible portion of the transmission shaft (40) is inserted through a bellows (100).
Claims16
A portable powered cutter comprising:
- a power source;
- an operation tube connected to the power source;
- a blade holder connected to a forward end of the operation tube;
- a rotary blade supported by the blade holder;
- and a transmission shaft inserted through the operation tube for transmitting rotational output of the power source to the rotary blade;
- wherein the blade holder is pivotable about a transverse axis perpendicular to a longitudinal axis of the operation tube by pressing the rotary blade against a ground surface, the blade holder being held at a selected pivotal position by a friction mechanism or an engaging mechanism,
- wherein the transmission shaft is flexible at least at a portion between the forward end of the operation tube and the blade holder, the flexible portion of the transmission shaft being inserted through a flexible tube.
