发明名称 LATCH MECHANISM GUIDE
摘要 An apparatus and method for guiding a fish into engagement with a latch mechanism on a fishing tool, by hydraulically expanding the ends of a set of fingers into contact with a bore hole. The ends of the fingers surround the fish and guide the fish and the latch mechanism together, as the tool is lowered, until the latch mechanism latches onto the fish.
