1. A slide rail assembly, comprising:a first rail having a front end and a rear end;
a second rail displaceable with respect to the first rail;
a third rail displaceable with respect to the second rail, the third rail having a front end and a rear end;
a first engaging mechanism movably mounted on the second rail;
at least one stopping member arranged on the first rail and including a disengaging portion; and
a second engaging mechanism movably mounted on the second rail, the third rail including a rear stop and being configured to push the second engaging mechanism via the rear stop and thereby displace the second rail from a first position in a first direction, and the disengaging portion of the at least one stopping member disengages the second engaging mechanism from the rear stop when the third rail is displaced to a predetermined position;
wherein the rear end of the first rail and the front end of the third rail define a first length therebetween when the second rail is displaced from the first position to the second position with respect to the first rail in the first direction and the third rail is displaced to a third position with respect to the second rail in the first direction and therefore extends out of the second rail;
wherein when the second rail is displaced from the second position to a fourth position in a second direction, the first length between the rear end of the first rail and the front end of the third rail is reduced to a second length, and the second rail is kept at the fourth position with respect to the first rail by the first engaging mechanism.
