The present invention discloses a locking mechanism having a locking member disposed with a fan-shape protrusion and a fan-shape notch, such that when the locking member is rotating, the jerk as a result of rotation can be reduced, and when the locking member is returned to its original position, a sufficient torsion can still be generated. Also, when the locking member is in the locking position, the fan-shape protrusions are positioned at the fan-shape notches. |
