In this article, we analyze tensor-vector-pseudoscalar(TVP) type of vertices

and 
in the frame work of three point QCD sum rules(QCDSR). According to these analysis, we calculate their strong form factors which are used to fit into analytical functions of 
. Then, we obtain the strong coupling constants by extrapolating these strong form factors into deep time-like regions. As an application of this work, the coupling constants for radiative decays of these heavy tensor mesons are also calculated at the point of 
. With these coupling constants, we finally obtain the radiative decay widths of these tensor mesons.
