Then prop the support rod 14 on the ground, and then start the cutting operation by pressing the button on the driving mechanism 1. The driving mechanism 1 will slowly push the blade inside the fixed ring 2 out, and under the cooperation of the rotating ring 3 and the fixed ring 2, the cable wrapped inside will be cut until it is cut off. Since there is support from the support rod 14, it is not necessary to hold the entire device all the time, which saves time and effort and reduces the degree of worker fatigue. When it is necessary to continue cutting the next cable, pull the insertion rod 7 to compress the spring one 5 and drive the baffle 6. At the same time, the spring two 9 will immediately push the sliding plate 10 to drive the connecting rod 11 to pop out, so that the stop block 12 resets to open the fixed ring 2 and blocks the outlet of the insertion rod 7. At this time, the work can continue, which saves time and effort and effectively improves work efficiency.
