A multi-function vehicle-carrying frame includes a chassis, a positioning frame, a connecting rod, two first clasping poles, two second clasping poles, two third clasping poles and a support. The chassis is U-shaped. The positioning frame is reverse U-shaped and inserted into the chassis. An adjustable clipping post is disposed on a top tube of the positioning frame, and both lateral pipes are locked with a movable buffer cushion. The connecting rod is fixed between the lateral pipes of the positioning frame. The first clasping poles are pivotally connected to the lateral pipes of the positioning frame, the second clasping poles are connected to the lateral pipes of the first clasping pole or the positioning frame, and the third clasping poles are connected to the ends of the connecting rod. The support is connected to the lateral pipes of the positioning frame. Thereby, the multi-function vehicle-carrying frame is stable and practical.
