主权项 1. A break away support ring apparatus comprising: a protuberance slicer and orientation device including: an annular support ring, the annular support ring being generally tubular;a protuberance slicer, the protuberance slicer being generally tubular and positioned within the annular support ring;a cylindrical sleeve, the cylindrical sleeve being generally tubular and having an inner diameter generally the same size as the internal diameter of the protuberance slicer, the cylindrical sleeve having a down-hole end with an outer edge and an up-hole end having a cut-out mating edge, the cylindrical sleeve including a pocket extending radially outward from the inner surface of the cylindrical sleeve; and a center body device, the center body device having an up-hole end and a down-hole end, the down-hole end coupleable to a probe-based tool, the center body device including: a shear linkage, the shear linkage pivotably coupled to the center body device and positioned to radially outwardly from the center body device in an extended position and to recede into a recess of the center body device in a retracted position, the shear linkage adapted to extend into the pocket of the cylindrical sleeve of the protuberance slicer and orientation device when the center body device is positioned within the protuberance slicer and orientation device;a cut out mating edge, the cut out mating edge being generally tubular and extending about the center body device, the cut out mating edge including a curved or angled profile positioned to mate with the first cut out mating edge of the protuberance slicer and orientation device when the center body device is positioned within the protuberance slicer and orientation device.
