and (fifth), finally, the first driving part 73 operates, the first conveying assembly drives the electric wire to continue conveying, and the second conveying assembly outputs the cut electric wire and continues conveying the subsequent electric wire, so that the cutting of the electric wire is completed.

It should be noted that after the wire is cut, the subsequent wire may be manually pulled to the second conveying assembly, or the first conveying assembly may push the subsequent wire to the second conveying assembly, where the height of the top side of the tool holder 54 is equal to or less than the height of the lowest point inside the first arc-shaped clamping piece 42, and the height of the top side of the tool holder 54 is equal to or less than the lowest point of the first transmission shaft 62 of the second conveying assembly.

Compared with the prior art, the positioning guide cutting device can clamp and convey wires with different specifications, has a wider application range, improves the utilization rate of the device, and avoids the increase of cost due to the fact that additional devices are purchased due to the limitation of use.
