Anti-slip safety tensioning device for automobile

An anti-slip safety tensioning device for automobile, comprising a driving handle assembly, a support assembly, and a a first band and a second band;

• wherein, the driving handle assembly is rotatable relative to the support assembly;
• the support assembly comprises two support lateral plates, an eccentric shaft having an eccentric bulge and two ends respectively inserted into the two support lateral plates, and a plurality of connecting shafts disposed between the two support lateral plates;
• the driving handle assembly comprises two driving handle lateral plates, a top shaft located at a front side of the driving handle assembly and between the two driving handle lateral plates, and a barrier assembly located at a rear side of the driving handle assembly and between the two driving handle lateral plates;
• the driving handle assembly is located between the two support lateral plates, and the two ends of the eccentric shaft respectively pass through the two driving handle lateral plates enabling the driving handle assembly to be rotated around the eccentric shaft to achieve unfolding and folding of the driving handle assembly relative to the support assembly;
• and when the driving handle assembly is folded relative to the support assembly, the eccentric shaft is located on a rear side of the top shaft and the eccentric bulge of the eccentric shaft faces the top shaft;
• the first band being longer than the second band, the first band having a free end wrapped around the eccentric shaft, and the free end of the first band passes through a gap between the eccentric shaft and the top shaft.
