ライブラリが必要です。

\begin{document}
 \begin{tikzpicture}
 \draw[decorate,decoration={coil}] (0,3) -- (0,-3);
 \end{tikzpicture}
\end{document}

coilにオプションをつけることができます。amplitude, segment length, aspect

amplitudeの違い

 \begin{tikzpicture}
 \draw[decorate,decoration={coil,amplitude=2cm}] (-3,3) -- (-3,-3);
 \draw[decorate,decoration={coil,amplitude=3.5cm}] (0,3) -- (0,-3);
 \draw[decorate,decoration={coil,amplitude=5cm}] (3,3) -- (3,-3);
 \end{tikzpicture}

segment lengthの違い

 \begin{tikzpicture}
 \draw[decorate,decoration={coil,segment length=5}] (-3,3) -- (-3,-3);
 \draw[decorate,decoration={coil,segment length=10}] (0,3) -- (0,-3);
 \draw[decorate,decoration={coil,segment length=15}] (3,3) -- (3,-3);
 \end{tikzpicture}

aspectの違い

 \begin{tikzpicture}
 \draw[decorate,decoration={coil,aspect=0.4}] (-3,3) -- (-3,-3);
 \draw[decorate,decoration={coil,aspect=0.7}] (0,3) -- (0,-3);
 \draw[decorate,decoration={coil,aspect=1}] (3,3) -- (3,-3);
 \draw[decorate,decoration={coil,aspect=2}] (6,3) -- (6,-3);
 \end{tikzpicture}
