看看如何用代码块功能 [https://wenda.latexstudio.net/q-1541.html](https://wenda.latexstudio.net/q-1541.html "https://wenda.latexstudio.net/q-1541.html")

通过自定义to path给你实现了一个，用pic也行，没必要自定义一个node shape ```tex \documentclass[tikz, border=1cm]{standalone} \usetikzlibrary{shapes.geometric} \usetikzlibrary{calc} \tikzset{ myellipse/.style args={#1 and #2}{ draw, shape=ellipse, minimum width=#1, minimum height=#2, }, cable pos/.store in=\cablepos, cable pos=.5, cable width/.store in=\cablewd, cable width=2cm, cable x radius/.store in=\cablex, cable x radius=.1cm, cable y radius/.store in=\cabley, cable y radius=.4cm, cable text/.store in=\cabletext, cable text=, cable node style/.store in=\cablesty, cable node style=, cable/.style={to path={ let \p1 = (\tikztostart), \p2 = (\tikztotarget) in let \n1 = {\x2 - \x1}, \n2 = {\y2 - \y1} in \pgfextra{\pgfmathsetmacro{\diffx}{\n1 / 1cm}} \pgfextra{\pgfmathsetmacro{\diffy}{\n2 / 1cm}} let \n{sqrt} = {sqrt((\diffx)^2 + (\diffy)^2)} in let \n{sign} = {\diffy > 0 ? 1 : (\diffy < 0 ? -1 : (\diffx > 0 ? 1 : -1))} in let \n{ang} = {\n{sign} * acos(\diffx / \n{sqrt})} in let \p{center} = ($(\p1)!\cablepos!(\p2)$) in let \p{left} = ($(\p{center}) - (\n{ang}:{.5*\cablewd})$) in let \p{right} = ($(\p{center}) + (\n{ang}:{.5*\cablewd})$) in let \p{upperleft} = ($(\p{left}) + ({\n{ang} + 90}:\cabley)$) in let \p{upperright} = ($(\p{right}) + ({\n{ang} + 90}:\cabley)$) in let \p{lowerleft} = ($(\p{left}) + ({\n{ang} - 90}:\cabley)$) in let \p{lowerright} = ($(\p{right}) + ({\n{ang} - 90}:\cabley)$) in -- (\p{left}) (\p{center}) node[rotate=\n{ang}, \cablesty] {\cabletext} (\p{upperleft}) -- (\p{upperright}) (\p{lowerleft}) -- (\p{lowerright}) {[rotate around={\n{ang}:(\p{left})}] (\p{left}) ++ (-90:\cabley) arc[ x radius=\cablex, y radius=\cabley, start angle=-90, end angle=270, ] } {[rotate around={\n{ang}:(\p{right})}] (\p{right}) ++ (-90:\cabley) arc[ x radius=\cablex, y radius=\cabley, start angle=-90, end angle=90, ] } ($(\p{right}) + (\n{ang}:\cablex)$) -- (\p2) \tikztonodes }} } \begin{document} \begin{tikzpicture} \foreach \x/\y/\z in {0/.3/2, 45/.4/2.5, 90/.5/3, 135/.6/3.5, 180/.7/4} { \typeout{aaa \x, \y, \z} \edef\a{\x} \edef\b{\y} \edef\c{\z} \draw[->] (0, 0) to[ cable, cable pos=\b, cable width=\c cm, cable text=cable, ] (\a:8cm); } \end{tikzpicture} \end{document} ```
