The indicating unit provides a first color area and a second color area for indicating the positions of the locking units. The associating unit is associated between the locking units and the indicating unit; when all of the locking units have been moved to the locked position, the associating unit associates the indicating unit to reveal the first color area; and when one of the locking unit is failed to move to the locked position, the associating unit associates the indicating unit to reveal the second color area.
