Abstract

A shearing hand piece tension lock ring 86 is formed from a resilient material having a generally circular cross-sectional shape and describing an arc of approximately 340 degrees. The tension lock ring 86 has a first end 74 configured to fit a recess (60, fig. 3a) of a shearing hand piece tubular bush (42, fig. 3a). The tension lock ring 86 has a second end 76 having a radially outwardly positioned rounded shoulder 88 and an end face 82 that faces the interior of the tension lock ring 86. The end face 82 is formed by cutting diagonally through a bend (90, fig. 5c) formed in the tension lock ring 86. The end face has the shape of an oval with a single axis of symmetry 94 (see fig. 6), or a truncated oval with a single axis of symmetry (see figures 7 & 8). The finishing of the second end 74 lessens the risk of snagging between the end of the tension lock ring and the interior of the shearing hand piece tensioning cap (46, fig. 1), and also lessens the risk of injury to an operator during assembly or servicing of the shearing hand piece.
