AI Technical Summary
Existing anti-skid chain tensioning devices require specially made flat wrenches, which limits their use and results in poor versatility of locking tools.
Design an anti-skid chain tensioning device. The plate has a round hole and a sliding groove. One end of the sliding groove is farther from the round hole than the other end. The plate also has a hexagonal hole. By rotating the plate, the chain spacing is shortened. It can be turned with a hexagonal wrench, making the connection with the tire tighter.
It achieves a tight bond between the anti-skid chain and the tire, preventing it from falling off. It is easy to use and highly versatile, and is compatible with most hex wrenches on the market.
