摘要： A support base for a child safety seat includes a support leg operable to retract and expand at a bottom of the support base, a first and a second locking mechanism, and a linking assembly. The support leg includes multiple segments, and a first and a second sliding connection each of which respectively coupling two adjacent ones of the segments. The first locking mechanism includes a first latch operable to lock the first sliding connection, and a first actuating part operable to urge the first latch to move for unlocking the first sliding connection. The second locking mechanism includes a second latch operable to lock the second sliding connection, and a second actuating part operable to urge the second latch to move for unlocking the second sliding connection. The linking assembly couples the two locking mechanisms so that the first and second sliding connections can be concurrently unlocked.
