Plug removal method and apparatus |
摘要 |
A tool for removing plugs from recesses obviates the need for a twist of the wrist in engaging a plug for removal. A plunger is carried by a housing and is supported for reciprocal axial motion between extended and retracted positions relative to the housing. A shaft of the plunger includes a first threaded section that is engaged in a nut carried by the housing and has threads pitched to allow relative axial motion to be converted to relative rotation between shaft and housing. A second threaded section of the plunger shaft is configured to tap into a plug in response to shaft rotation in a tapping direction, and has a shallower thread pitch than the first threaded section. |
