Provided are a set of fully human TSH receptor (TSHR)-blocking monoclonal antibodies targeting a CHK36 homolog cluster, a preparation method therefor, and an application thereof. The method comprises the following steps: using flow cytometry to sort plasma cells and single memory B cells that specifically recognize TSHR in peripheral blood of a patient with a high titer of TSH-blocking antibodies (TBAb), performing in vitro cloning of antibody light and heavy chains and performing recombinant expression, and using hTSHR-CHO cells to perform screening and validation of antibody properties to obtain a blocking monoclonal antibody that specifically targets human TSHR. The fully human TSH receptor-blocking monoclonal antibodies specifically bind to a TSHR, and effectively block signal transduction after a TSH binds to a receptor, inhibit the synthetic secretion of thyroid hormones, and significantly reduce and inhibit TSHR expression and fibrosis in orbital fibroblasts of effector cells associated with thyroid-related ocular diseases. The fully human TSH receptor-blocking monoclonal antibodies have broad application prospects in the treatment of Graves' disease (GD) and other diseases caused by hyperthyroidism, such as thyroid eye disease (TED).
