wherein after the second rail is displaced to a lagging position relative to the first rail, the first rail displacing along an opening direction drives the first feature and the compensating device in the first state to abut against each other to drive the second rail to synchronously displace together with the first rail along the opening direction for a first predetermined distance until the compensating device is driven to move from the first state to the second state;
wherein after the second rail is displaced to an advancing position relative to the first rail, the first rail displacing along the opening direction drives the compensating device in the first state to displace along the opening direction to cause the blocking portion of the third rail and the compensating device in the first state to block each other to prevent a displacement of the second rail relative to the third rail along the opening direction to stop the second rail until the first rail is displaced along the opening direction over a second predetermined distance to drive the first feature and the compensating device in the first state to abut against each other to drive the compensating device to move from the first state to the second state, and when the compensating device is in the second state, the blocking portion of the third rail does not block the compensating device;
wherein after the second rail is displaced to the lagging position relative to the first rail, the first rail displacing along the opening direction drives the first feature and the second feature of the compensating device in the first state to abut against each other, so as to drive the second rail to synchronously displace together with the first rail along the opening direction for the first predetermined distance;
wherein one of the first feature and the second feature comprises a first guiding portion, after the second rail is displaced to the advancing position relative to the first rail, the first rail displacing along the opening direction drives the blocking portion of the third rail and the predetermined feature of the compensating device in the first state to block each other to stop the second rail until the first rail is displaced along the opening direction over the second predetermined distance to drive the first feature and the second feature of the compensating device in the first state to abut against each other by the first guiding portion, so as to drive the compensating device to move from the first state to the second state, and when the compensating device is in the second state, the blocking portion of the third rail does not block the predetermined feature of the compensating device.
