10000 what's wrong with the spinning wheel's oblique cup throwing knot?

The explosive knotting of electric wires has something to do with the figure-8, but it's not very big, because now I'm used to throwing, and I won't knot without the figure-8. The advantage of using it is to protect the conductor, reduce the distortion of the conductor and prolong the service life of the extension line. Recommended use. Second, it is related to the thickness and material of the thread. If the thread is thick and hard, it is easier to explode and knot. The main line should be selected with moderate toughness and hardness. At present, PE wire is generally used in Luya line, and carbon wire can be used as lead wire, which is not suitable for main line.
