Patent attributes
The safety cutter supports adjustment of the blade length which is allowed to expose outside the housing. It includes a housing, a blade carrier, a blade, a threaded shaft, a nut and a guiding member. The blade carrier is slidable along a blade carrier track provided within the housing. The blade removably engages a forward end of the blade carrier. The threaded shaft is disposed along the blade carrier track. The nut is restricted from axial rotation and engaged with the threaded shaft in such a way that rotation of the threaded shaft drives the nut to move axially along the threaded shaft. The guiding member is fixedly coupled to the blade carrier for guiding movement of the blade carrier and positioned to be movable between a rear end of the blade carrier track and the nut.
