Abstract

A hand-held optical fiber cutting device comprises a pedestal, a cutting mechanism sliding on the pedestal, and a cable folder fixed at the cutting mechanism and provided with a folding mount. An optical fiber press plate of the cutting device is opened via a button switch arranged on the pedestal, so an optical fiber to be cut is placed in an optical fiber slot of the pedestal. Then the optical fiber plate is closed to fix the optical fiber. The cutting mechanism and the cable folder are pushed to move towards the optical fiber. After the optical fiber is cut by a cutter of the cutting mechanism to a preset depth, a pushing rod of the cable folder jacks the folding mount to complete cable folding. Moreover, a single person can complete cutting of the optical fiber with the optical fiber cutting device just by holding the cutting device in a hand.
