• and
• an internal button, located in the casing, wherein the sliding assembly is located between the exterior button and the internal button,
• when the sliding assembly is in a closed position relative to the casing, the second side of the exterior button is retracted within the casing,
• when the sliding assembly moves from the closed position to an open position along the first direction relative to the casing, the second side of the exterior button protrudes from the opening and protrudes beyond the outer surface, the exterior button is adapted to be pressed, driving the pusher to move along the second direction to trigger the internal button.
