The invention relates to an anti-skidding eccentric automotive safe tensioning device. The anti-skidding eccentric automotive safe tensioning device comprises a driving handle assembly, a bracket assembly, a long binding band and a short binding band, wherein the driving handle assembly is arranged between a left bracket side sheet and a right bracket side sheet of the bracket assembly and is rotatably connected to an eccentric shaft of which two ends are fixed with the left bracket side sheet and the right bracket side sheet respectively; under the folded state of the driving handle assembly, the eccentric shaft is positioned on the rear side of an ejection shaft, and an eccentric bulge of the eccentric shaft faces one side of the ejection shaft; the long binding band is connected to the eccentric shaft, and the free end of the long binding band penetrates through a clearance between the eccentric shaft and the ejection shaft. When the driving handle assembly rotates to be unfolded, the clearance between the driving handle ejection shaft and the eccentric shaft is maximized, and an operator can conveniently thread the binding bands; when the driving handle assembly rotates to be folded, the clearance between the driving handle ejection shaft and the eccentric shaft is narrowed, and a braid is exactly compressed, so that the anti-skidding safe fastening effect is achieved.
