When the outer protective layer 41 on the cable 40 contacts the cable sheath slitting head 9, it will be cut. When the tip of the wire-dividing mechanism 2 contacts the filling layer 43, the filling layer 43 will be stretched open and the inner core 42 will be pushed open in four directions. Then, the fifth telescopic electric cylinder 24 will be driven to move in a process so that the alignment seat 28 can support the root of the inner core 42. Then, the first-stage telescopic electric cylinder 8 will be driven to move in a process so as to push the inner core 42 into the wire groove 10 on the wire-dividing mechanism 2. When the laser cutting head 38 passes through the corresponding cutting point, the inner core 42 can be cut by the laser cutting head 38.
