[0046] Instructions for use of fixture:

[0049] Place the auto-focus optical image stabilization motor lower part 6 flatly in the motor lower part positioning groove 2-2-1 so that the bottom surface of the auto-focus optical image stabilization motor lower part contacts the auto-focus optical image stabilization motor lower limit surface 3-6-3.

[0050] Autofocus optical image stabilization motor upper assembly instructions:

[0051] Place the autofocus optical image stabilization motor upper part 5 flatly in the motor upper part positioning groove 1-2-1 so that the upper surface of the autofocus optical image stabilization motor upper part contacts the motor upper limit surface 1-2-3; the autofocus optical image stabilization motor upper part is tightly attracted to the motor upper part positioning surface 1-2-2 and the motor upper limit surface 1-2-3 by the internal magnet.
