The present application discloses a retractable tube mechanism and a stroller. The retractable tube mechanism includes: an outer tube; an inner tube inserted into the outer tube and axially movable relative to the outer tube; and a locking device including a locking member and a pulling member both arranged in the inner tube. The locking member is operably connected to the pulling member. The locking member has a locked state in which an axial movement of the inner tube relative to the outer tube is restrained, and an unlocked state in which the axial movement of the inner tube is allowed. When the pulling member moves under the action of a pulling force, the pulling member drives the locking member to switch from the locked state to the unlocked state. When the pulling force is removed, the locking member tends to return from the unlocked state to the locked state.
