In this study, the structural composition and working principle of the single wedge two‐way backstop are analysed, and the factors affecting the self‐locking of the single wedge two‐way backstop are explored. Two wedge shapes are established, the contact stress between the wedge and the outer casing is calculated by ANSYS and compared with the stress value calculated by Hertz theory, to verify the applicability of the finite element method.
