[0002] There are many specifications of wire and cable products, and the appearance of the finished products varies according to the specifications. Among them, small-sized finished cables are mainly coiled to facilitate stacking and use. Some cables with irregular outer diameters are mainly coiled by semi-automatic coiling machines, and cables with uniform outer diameters are coiled by fully automatic coiling machines. Among them, semi-automatic coiling machines are equipped with a variety of coiling heads because of the wide variety of coiling types.

[0003] During normal production, after the operator completes a looping operation, the operator needs to manually remove the outer disc of the looping head to take out the looped wire. Then the outer disc of the looping head needs to be manually installed again. Repeating the action results in long-term repeated removal of the looping disc, which increases the labor intensity of the operator and reduces work efficiency. Summary of the invention
