插入锁定式销与索环及相关方法
摘要：
一种销与索环紧固件被装配成运输构造，在运输构造中，销(31)被保持在相对于索环(24)的第一位置而索环的纵向延伸的支腿构件处于未展开状态。配合构件设置在销和索环上以在锁定构造中彼此接合，在锁定构造中，销被保持在相对于索环的第二位置以使纵向延伸的支腿构件处于横向展开状态。驱动构件(38)设置在销上以与接合部件的孔的周边接合从而在将装配后的销与索环插入到接合部件的孔中的同时使接合部件自动地将销从第一位置驱动到第二位置。
摘要（英）：

A pin and grommet fastener is assembled into a shipping configuration in which the pin is retained in a first position relative to the grommet with longitudinally extending leg members of the grommet in an unexpanded state. Cooperating members are provided on the pin and the grommet to engage each other in a locking configuration in which the pin is retained in a second position relative to the grommet causing the longitudinally extending leg members to be in a laterally expanded state. A driving member is provided on the pin to engage a periphery of an aperture of a joining part to cause the joining part to automatically drive the pin from the first position to the second position simultaneously with the insertion of the assembled pin and grommet into the aperture of the joining part.
