When the cutting tool 108 cuts the cable, the cutting tool 108 will have an impact force. After the cutting tool 108 has cut the cable, it will enter the knife edge groove 302 of the cutting knife guard plate 301 and move downward. The cutting knife guard plate 301, the piston guide rod 307 and the oil sleeve 308 can reduce and absorb the impact force of the cutting tool 108. When the cutting tool 108 moves upward, the spring 305 will then rebound the cutting knife guard plate 301 to its original position. The knife edge groove 302 of the cutting knife guard plate 301 corresponds to the position of the cutting tool 108. During actual use, when the operator places the communication cable on the cutting table 101 and starts the cutting tool 108 to cut the communication cable, the cutting tool 108 will have an impact force.
