Claim 10:
11. The opening device of claim 1, further comprising:
a dial mounted on a surface of the inside handle;
a blade located inside an internal cavity of the inside handle;
a further rod connecting the dial and the blade; and
the first gear includes a sloped back side engageable with the blade; wherein when the blade is rotated by the dial via the further rod in a first direction:
the rotation of the blade causes, via the sloped back side, the first gear to move toward the second gear and engage with the second gear, thereby allowing the inside shaft to be rotated by the outside handle to unlock the door lock; and
the first gear and the second gear are engaged until the blade is rotated by the dial via the further rod in a second direction, the second direction being opposite to the first direction.
