One of the teleportation versions is applied to convey an entangled two-qubit system via a class of a two-qubit XYZ Heisenberg chain model. At thermal equilibrium, the exact solution of the XYZ model with an external magnetic field and the Kaplan&#x2013;Shekhtman&#x2013;Entin-Wohlman&#x2013;Aharony interaction (KSEWA-interaction) is proposed in <inline-formula> <tex-math notation="LaTeX">$X$ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">$Z$ </tex-math></inline-formula> direction. The teleported quantum Fisher information is studied, where we estimate the weight parameter <inline-formula> <tex-math notation="LaTeX">$\theta $ </tex-math></inline-formula>, temperature and the strength parameter of KSEWA-interaction. It is found that, the strength of the KSEWA-interaction and the magnetic field be of benefit in the case of estimating the weight function. Meanwhile, the temperature decreases the teleported information.
