The utility model discloses studs and a wheel-frame fixing device with the same. The wheel-frame fixing device is applicable to positioning a wheel frame on a hub. The hub comprises a side surface and screw holes formed by concaving of the side surface; penetrating holes are formed in the wheel frame; each stud comprises a force applying column body, a first thread column body and a second thread column body; each force applying column body comprises a first end surface and a second end surface opposite to the first end surface; the profile of each force applying column body, which is vertical to a central axis of each stud, is non-circular; each first thread column body extends convexly from each first end surface towards the direction far away from each second end surface; each first thread column body is used for being rotatably locked at the screw hole of the hub; each second thread column body extends convexly from each second end surface towards the direction far away from each first end surface; and each second thread column body extends convexly out of the side surface of the hub and is used for sheathing of the penetrating hole of the wheel frame. Therefore, the wheel frame can be rapidly and conveniently positioned on the hub in advance.
