Abstract
A head assembly for a drilling operation. The assembly includes a retractor case comprising a retractor pin slot. The assembly includes a body that comprises a body pin slot, wherein an interior space of the body is configured to receive the retractor case. The assembly includes a latch ear coupled to the body, wherein at least a portion of the latch ear extends outward relative to the body. The assembly includes an expansion block at least partially disposed within an interior space defined by the retractor case. The assembly is such that a position of the expansion block along a longitudinal axis of the assembly determines whether the latch ear is in an extended position or a retracted position relative to the body sidewall.
