    摘要： The assembly includes a coil form having a coil receiving portion and an internally threaded center hole extending longitudinally therethrough. The internally threaded surface has an axial groove therein extending along its length, and the groove is generally concentric to the threaded surface and has a depth greater than the depth of the thread. A thin flat resilient strip is positioned within the groove. The strip has a width that substantially occupies but is less than the width of the groove and is of a thickness that is less than the distance that the depth of the groove exceeds the depth of the thread.
