In summary, the child carrier 100 of the present invention can enable the lock release mechanism 5 to dock with the first linkage mechanism 3 by rotating the rider 2 to the first position, and enable the first linkage mechanism 3 to release the first locking member 13 by the lock release mechanism 5, so that the first locking member 13 releases the front wheel seat 11, thereby adjusting the front wheel 17 pivoted with the front wheel seat 11 to be a universal wheel, or enable the lock release mechanism 5 to dock with the second linkage mechanism 4 by rotating the rider 2 to the second position, and enable the second linkage mechanism 4 to release the second locking member 14 by the lock release mechanism 5, so that the second locking member 14 releases the rear wheel seat 12, thereby adjusting the rear wheel 18 pivoted with the rear wheel seat 12 to be a universal wheel. Accordingly, the child carrier 100 of the present invention can adjust the front wheels 17 or the rear wheels 18 to universal wheels to meet different needs of users.

The foregoing disclosure is only illustrative of the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
