垂直 TikZ 箭头锚定在目标的中心

考虑这个例子：

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
    \node[left] at (0,0) (Source) {Source};
    \draw [very thick, ->] (0.15,-0.02) -- (2.5,0.48);
    \node[right] at (2.5,0.5) (Target1) {abcdefgh};
    \node at (Target1) (Target1arrow) {};
    \draw [very thick, ->] (2.35,0.52) -- (0,0.02);
    \node[right] at (2.5,-0.5) (Target2) {abcdefg};
    \node at (Target2) (Target2arrow) {};
    \draw [very thick, ->] (0.15,-0.02) -- (2.5,-0.5);
    \draw [very thick, ->, shorten <= .5ex, shorten >= .5ex] (Target1arrow) -- (Target2arrow);
\end{tikzpicture}
\end{document}

我知道垂直箭头从 的中点开始Target1并指向 的中点Target2，但在这种情况下，这两个目标的长度几乎相同，如果箭头是直的，看起来会更好。换句话说，我希望箭头的起点固定在 的中心点Target2。我尝试添加anchor = Target2.base此箭头的绘制功能，但没有效果。

首先，可以选择将一个节点置于另一个节点下方（Pier Paolo 解释道）。

还有(node1 |- node2)垂直绘制线条的语法。在这种情况下，箭头的末端写为(Target1arrow |- Target2arrow.north)。

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
  \node[left] at (0,0) (Source) {Source};
  \draw [very thick, ->] (0.15,-0.02) -- (2.5,0.48);
  \node[right] at (2.5,0.5) (Target1) {abcdefgh};
  \node at (Target1) (Target1arrow) {};
  \draw [very thick, ->] (2.35,0.52) -- (0,0.02);
  \node[right] at (2.5,-0.5) (Target2) {abcdefg};
  \node at (Target2) (Target2arrow) {};
  \draw [very thick, ->] (0.15,-0.02) -- (2.5,-0.5);
  \draw [very thick, ->, shorten <= .5ex, shorten >= .5ex] (Target1arrow) -- (Target1arrow |- Target2arrow.north);
\end{tikzpicture}
\end{document}
