这真是太乱了，但也许有人可以稍微整理一下。（例如，将使用的节点样式声明为“真实”节点样式 [ \node[NAME] …] 等等。）

使用 s 可以获得稍微短一点的版本pic：

\documentclass[border=5pt,tikz]{standalone}
\usetikzlibrary{arrows,calc}
\tikzset{pics/.cd,
  broken line/.style={
    code={
      \fill [white] (-1,-0.25) rectangle (1,0.25);
      \draw (-0.5,-0.25) to[bend left=40] (0,-0.25) to[bend right=40] (0.5,-0.25);
      \draw (-0.5,0.25) to[bend left=40] (0,0.25) to[bend right=40] (0.5,0.25);
    }
  },
}
