发明名称 Locator shifter tool
摘要 An improved locator shifter tool useful in a string of well operating tools. When the tool string is lowered into compatible internal profiled grooving in a well conduit, profiled keys on the locator shifter tool move outwardly into the profiled grooving, stopping downward movement of the shifting tool and tool string. A downward force on the tool string will now operate the locator shifter tool to lock connected in the profiled grooving in the conduit. To disconnect the locator shifter from the profiled grooving, an upward force on the tool string will operate the locator shifter tool to cam the keys inwardly from the conduit grooving, disconnecting the locator shifter and tool string for raising through the conduit back to the surface.
