发明名称 Multi-position fixture
摘要 For lifting loads there is provided an eyebolt with an annular ring swivelly mounted on a stud so as to freely rotate in a horizontal plane through a full 360 DEG . A lifting loop has oppositely disposed pivot pins in swivel engagement with the annular ring to allow the loop to pivot in a vertical arc as well as to rotate about the stud. The stud in turn is adapted to be anchored in fixed position to the load, whatever the load may be. Snap rings at free ends of the pivot pins serve to resist pulling the pins free of the annular ring when a heavy lifting force is applied to the lifting loop.
