Hand guided electrical tool clutch - has drive wheel with wedge shaped projections to engage drive rollers of simple design and low friction

摘要

The hand guided hedge trimmer has a clutch. The drive wheel (15) has wedge shaped projections (21) on its inner surface (20), which engage with roller projecting radially over the inner and outer surface (24,25) of the wall of the output casing (16) in recesses (22) in its wall. By releasing a radial play for the rollers (23), they can jump over the wedge shaped projections, thus separating drive and output from each other. USE/ADVANTAGE - The clutch is largely friction-independent and consists of simple elements.
