摘要

A sensing mechanism (12) for detecting user contact with an active portion (26) of the power tool (10) is provided. In addition, a safety mechanism (14 ) for preventing prolonged user contact with the active portion (26) of a powe r tool (10) is provided. The safety mechanism (14) is configured to actuate up on receipt of a signal from the sensing mechanism (12). According to a first aspect, the safety mechanism (14) is arranged to rapidly displace the active portion (26) away from a user extremity. Alternatively, according to a secon d aspect, the safety mechanism (14) is arranged to rapidly urge an extremity o f the user away from the active portion (26) of the power tool (10).
