[0019] By buckling the spring buckles on both sides of the tension spring to the first pull ring and the second pull ring respectively, a pulling effect on the adjusting rod is achieved. When the quick-frozen food is conveyed on the conveying chain, when the first link pieces and the second link pieces bear the quick-frozen food, the tension spring stretches and cooperates with the adjusting rod to move in the movable slots, realizing the self-adaptive adjustment of the tension of the conveying chain and avoiding the conveying chain from breaking due to excessive tension during use.
