The second rail can be displaced with respect to the first rail and is provided with a working feature. The third rail can be displaced with respect to the second rail. The switching member is disposed on the third rail and is configured to contact the working feature when the third rail reaches a predetermined retracted position after being displaced from an extended position in a retracting direction, in order for the third rail to displace the second rail to a predetermined position in the retracting direction via the switching member.
