To sum up, the child carrier 100 of the present invention can make the unlocking mechanism 5 and the first linkage 3 butt joint by rotating the rider 2 to the first position, and drive the first linkage 3 to unlock the first locking member 13 through the unlocking mechanism 5, so that the first locking member 13 unlocks the front wheel seat 11, thereby adjusting the front wheel 17 pivoted with the front wheel seat 11 into a universal wheel; or, the driver 2 is rotated to the second position, so that the unlocking mechanism 5 is in butt joint with the second linkage mechanism 4, the unlocking mechanism 5 drives the second linkage mechanism 4 to unlock the second locking piece 14, the second locking piece 14 is unlocked, and the rear wheel seat 12 is adjusted to be a universal wheel by the rear wheel 18 pivoted with the rear wheel seat 12. Therefore, the child carrier 100 of the present invention can adjust the front wheel 17 or the rear wheel 18 to be a universal wheel to meet different requirements of users.

The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
