Abstract : Let $A$ be an expansive dilation on $\mathbb{R}^n$,
and $p(\cdot):\mathbb{R}^n\rightarrow(0,\,\infty)$ be a variable exponent function satisfying the globally log-H\"{o}lder continuous condition. Let $H^{p(\cdot)}_A({\mathbb {R}}^n)$ be the variable anisotropic Hardy space defined via the non-tangential grand
maximal function. In this paper, the author obtain
the boundedness of anisotropic convolutional $\delta$-type Calder\'on-Zygmund operators
from $H^{p(\cdot)}_{A}(\mathbb{R}^n)$ to $L^{p(\cdot)}(\mathbb{R}^n)$ or from $H^{p(\cdot)}_{A}(\mathbb{R}^n)$ to itself.
In addition, the author also obtain the duality between $H^{p(\cdot)}_ A(\mathbb{R}^n)$ and the anisotropic Campanato spaces with variable exponents.
