Whenever the shear support rod 42 is at the bottom, the copper wire cutter 43 can cut the copper wire. Whenever the vertical height of the shear support rod 42 changes, it will drive the driving slide bar 8 to slide inside the slide bar support block 44. When the driving slide bar 8 slides up and down, it will drive the first slide block 33 located above to slide on the first slide rail 32, and drive the guide support block 7 and the first slide block 33 located below to slide on the first slide rail 32.
