The invention discloses a fender fixing bolt. The fender fixing bolt comprises a pre-tightening bolt and a fastening bolt, wherein the pre-tightening bolt comprises a first nut and a first screw rod, wherein a containing groove is formed in the first nut, and a containing cavity communicated with the containing groove is formed in the first screw rod; the first screw rod comprises a connecting section and an adjusting section, the connecting section connects the first nut and the adjusting section, the adjusting section is divided into at least two adjusting blocks along a center line, and the adjusting blocks are connected with the connecting section in a bent mode; the diameter of the containing cavity is gradually reduced in the direction away from the connecting section; the fastening bolt comprises a second nut and a second screw rod, the second nut is matched with the containing groove, and the second screw rod is matched with the containing cavity; and when the second screw rod is gradually pushed into the containing cavity, the second screw rod enables the adjusting block to be bent towards the periphery. By designing the fender fixing bolt convenient to disassemble, quick and convenient disassembly and assembly without an auxiliary tool are achieved.
