| 摘要 |
The invention relates to a flexible coupling comprising a lower assembly (10) having a spigot member (20), and an upper assembly (60) having a recess adapted to receive the spigot member, thereby allowing articulation of the upper assembly (60) with respect to the lower assembly (10) in any direction. A complementary indexing means is adapted to circumferentially align the lower assembly (10) and the upper assembly (60), and a single resilient member (65) interconnects the lower and upper assemblies, wherein the lower and upper assemblies are urged into mutual engagement against said articulation. |
