In this article, we analyze the strong vertexes $\Sigma_{ c}^{ *}ND$ and $\Sigma_{ b}^{ *}NB$ using the three-point QCD sum rules under the Dirac structure of $q\!\!\!/p\!\!\!/\gamma_{ \mu}$. We perform our analysis by considering the contributions of the perturbative part and the condensate terms of $<\overline{ q}q>$ and $<\frac{ \alpha_{ s}}{ \pi}GG>$. After the form factors are calculated, they are then fitted into analytical functions which are used to get the strong coupling constants for these two vertexes. The final results are $g_{ \Sigma_{ c}^{ *}ND}=7.19^{ +8.49}_{ -3.11}\pm1.76$ and $g_{ \Sigma_{ b}^{ *}NB}=10.54^{ +15.59}_{ -5.23}\pm1.82$.
