Abstract
The present invention relates to a safety cutter including a housing which receives a trigger, a transmission member, a pusher, a blade carrier and a blade. The transmission member is engaged operatively with the trigger via a gear assembly. The gear assembly allows the safety cutter to move the blade outward for a longer distance than conventional safety cutters. To prevent the gear assembly and the trigger rack portion from being displaced by tension generated during cutting, a first limiting member and a pair of second limiting members are provided in the housing. The blade carrier is releasably engaged with the transmission member to achieve automatic retraction of the blade into the housing after the blade leaves the cutting surface even if the trigger is not released.
