The invention discloses an externally-hung anti-slipping device for a vehicle hub, and belongs to the technical field of automobile parts. The device comprises a body, a plurality of through holes corresponding to bolt holes of an external hub are formed in the body, the body is detachably connected with the external hub through bolts and the through holes, the device further comprises a plurality of contact pieces used for making contact with the ground, the contact pieces are connected with the body in a sliding mode, and a rotating mechanism is further arranged on the body. The rotating mechanism is provided with a rotating disc, the rotating disc is provided with guide grooves in one-to-one correspondence with the contact pieces, one part of each contact piece extends into the corresponding guide groove to be in sliding connection with the corresponding guide groove, the center distance between one end of each guide groove and the rotating disc is L1, and the center distance between the other end of each guide groove and the rotating disc is L2. The difference between L1 and L2 is the sliding stroke of the contact piece on the body. The device is detachably connected with the automobile hub through the through holes, can be used immediately after being mounted, and simultaneously drives a plurality of contact pieces to extend and retract through a rotating mechanism, so that the anti-slip function is realized, and the cost is reduced.
