Abstract: Trailer for stroller includes a wheel frame with a lifting seat, and a push rod capable of sliding along the movement direction of front and rear wheels, which can be folded between the wheel frame and the seat. The push rod drives the seat to rise and fall; and a locking structure used for locking the push rod to limit the slide of the push rod when the seat rises is disposed between the push rod and the wheel frame. The seat is driven to rise when the push rod slides and is pulled up, and the seat is driven to fall when the push rod slides and is retracted; and the locking structure ensures the stability of the seat.
