[0001] The utility model relates to the technical field of line cutting equipment, in particular to a line end multi-stage cutting processing device. Background Art

[0002] Everyday electrical appliances are connected to circuits through external lines. For the production of lines, it is usually necessary to quantitatively cut a line wound on a reel into wires of appropriate lengths to facilitate the subsequent processing and production of the wire ends. At present, the line is usually cut manually after being pulled to a suitable length, and the cutting operation can only be carried out one by one during the cutting process, which has low work efficiency and cannot meet the requirements of large-scale processing. At the same time, during the cutting process, manual assistance is required to press and position the line, which is complicated to operate and labor-intensive. Utility Model Content

[0018] 4.
