The strong coupling constants among mesons are very important quantities asthey can provide useful information on the nature of strong interaction amonghadrons as well as the QCD vacuum. In this article, we investigate the strongvertices of the $D^{\ast}_{s}D_{s} \eta^{(\prime)}$ and $B^{\ast}_{s}B_{s}\eta^{(\prime)}$ in the framework of the QCD sum rule approach choosing the$\eta$ or $D_{s} (B_{s})$ meson as an off-shell state. We obtain the results$g_{D_s^*D_s\eta}=(1.46\pm 0.30)GeV^{-1}$, $g_{D_s^*D_s\eta^{\prime}}=(0.74\pm0.16)GeV^{-1}$, $g_{B_s^*B_s\eta}=(5.29\pm 1.06)GeV^{-1}$ and$g_{B_s^*B_s\eta^{\prime}}=(2.29\pm 0.48)GeV^{-1}$ for the strong couplingconstants under consideration, which can be checked in future experiments.
