CUTTING HEAD FOR BUSH CUTTER, HEDGE CUTTER OR THE LIKE PROVIDED WITH IMPROVED MEANS FOR LOCKING A CUTTING WIRE

摘要

The invention concerns a cutting head (10) for bush cutter, hedge cutter or the like comprising a channel (11) for a cutting wire (40) and a mobile element (20) for locking the wire. The invention is characterized in that the locking element comprises a slide adapted to move linearly in a guide (15) which intersects the wire channel and is subjected to a force, le slide and the wire passage proximate the guide having working surfaces (11, 12) adapted to lock the wire by shearing effect. Thus the wire is better retained and the locking efficiency is substantially independent of the wire section (both in terms of shape and size).
