Abstract

A portable belt cutting device comprises a cutting head and a cutting blade movably arranged on the cutting head. The cutting head has a drive mechanism to move the blade from a retracted position to an extended position, such that the blade severs a belt. The drive mechanism is coupled to the blade such that the blade is actively driven in both directions between the retracted position and the extended position. In some embodiments, the drive mechanism comprises a drive spindle which engages a thread formed in the cutting head. The spindle is bi-directionally movable and comprises a torque input geometry. In another embodiment the drive spindle and blade comprise connecting elements that form a positive connection when engaged.
