1. A lock mechanism comprising:
a housing;
an interior bore extending through the housing, the interior bore having a center axis;
a first annular surface inside the housing, the first annular surface extending around the interior bore and around the center axis, the first annular surface is positioned in a plane that is oriented at an angle relative to the center axis and the first annular surface is a beveled surface relative to the center axis;
a second annular surface inside the housing, the second annular surface extending around the interior bore and around the center axis, the second annular surface is positioned in a plane that is oriented at an angle relative to the center axis and the second annular surface is a beveled surface relative to the center axis;
a lock key, the lock key having a ring portion inside the housing extending around the interior bore;
an object having a length extending through the interior bore and through the ring portion of the lock key; and
the ring portion of the lock key being configured to be movable in the interior bore toward the first annular surface where when the ring portion engages in surface engagement around and against the first annular surface the ring portion is configured to engage against the length of the object extending through the interior bore and through the ring portion and prevent movement of the length of the object relative to the housing and the ring portion being configured to be movable in the interior bore away from the first annular surface where when the ring portion disengages from the first annular surface the ring portion is configured to disengage from the length of the object extending through the interior bore and through the ring portion and enable movement of the length of the object through the interior bore relative to the housing.
