Stroller frame

A stroller frame includes a bottom pipe, a rear foot, a handle, a carrier device, and a linking component. The rear foot is pivoted to the bottom pipe and the handle. A rear end of the carrier device is detachably connected to the rear foot. The linking component is pivotally bendable. Two opposite ends of the linking component are pivoted to the handle and the bottom pipe respectively. A middle portion of the linking component is pivoted to the rear foot. A front end of the carrier device is pivoted to the linking component in an engageable manner, and the linking component drives the carrier device to be folded when the stroller frame is folded. Therefore, the stroller frame can be folded into a smaller size easily, which is convenience for storage and transportation. Furthermore, depending on different situations, the carrier device can be detached from the stroller frame.
