a flat or recessed portion 78. A washer member (not shown) is
provided between lock 72 and locking member 74 to effect
rotational movement of locking member 74 about its axis when
lock 72 is locked and unlocked. To accommodate lock 72 and
locking member 74, bore 84 of varying diameter is provided
through boss 70 into housing 14. Bore 84 intersects tube 30
and produces a slot or aperture 86 which intersects passage
38, as shown in Figure 1. Bore 84 is aligned relative to
passage 38 such that arcuate surface 76 of locking member 74
is partially disposed within passage 38 when locking member 74
is in a first position, and recess 78 is oriented toward
passage 38 when member 74 is rotated 180° to a second
position. Further in this respect, bore 84 is disposed
relative to bore 64 such that when spherical member 60 is
aligned with a groove 50 on rod 46, locking member 74 is
likewise aligned with a groove 50 on rod 46. Spherical
bearing 60 and locking member 74 are disposed opposite each
other in housing 14 such that they align with the same groove
50 on rod 46.
