| 摘要 | A method and apparatus for locking an externally threaded member in place. An apparatus comprises a number of internally threaded members and a shape memory element associated with the number of internally threaded members. The number of internally threaded members is configured to engage the externally threaded member. Changing a baseline shape of the shape memory element to a modified shape either prevents or allows movement of the number of internally threaded members relative to the externally threaded member. | ||
