[0002] As a common device for preventing a vehicle from skidding in rainy and snowy weather, an anti-skid chain plays an important role in the safe driving of a vehicle. The installed anti-skid chain needs to maintain an appropriate tightness on the circumferential side of the tire to prevent the anti-skid chain from loosening during vehicle driving and causing harm to vehicle driving. Usually, the anti-skid chain is tensioned and fixed on the side of the vehicle wheel hub, and a traditional anti-skid chain tensioning device uses a ratchet locking device for locking and fixing.

Among them, the locking plate is rotatably connected to the base, and an elastic member is provided between the locking plate and the base. The elastic member is used to ensure that the locking plate abuts against one end of the ratchet. Usually, an elastic member fixing shaft is installed on the existing base, and the elastic member is fixed on the elastic member fixing shaft. During production, it is necessary to first install the elastic member fixing shaft on the base, and then fix the elastic member on the elastic member installation shaft. The installation is cumbersome, resulting in low assembly efficiency and high production cost. Summary of the Utility Model
