When the intermittent gear 32 is not meshed with the driving gear 35, the transmission ratio of the intermittent gear 32 to the driving gear 35 is set to adjust the specified conveying length of the optical cable, thereby determining the quantitative cutting length of the optical cable. When the two groups of movable tool holders 310 drive the cable cutter 311 to cut the optical cable, the intermittent gear 32 will no longer mesh with the transmission gear 36, and will mesh with the driving gear 35 again after rotating a certain angle, driving the feeding mechanism 20 to work and convey the cut material while conveying the new optical cable to the driving cutting mechanism 30. At the same time, when the intermittent gear 32 is no longer meshed with the transmission gear 36, under the action of the reset spring 315, the toothed plate 314 will drive the third connecting gear 312 to rotate in the opposite direction, so that the two movable tool holders 310 are reset.
