The first chain plate 1 and the third chain plate 2, and the second chain plate 30 and the fourth chain plate 31 are connected by a connecting assembly with the same structure. The first chain plate 1 and the second chain plate 30, as well as the third chain plate 2 and the fourth chain plate 31, are connected by a mounting assembly with a symmetrical arrangement. The mounting assembly includes a movable rod 32 disposed on the first chain plate 1 and a rotating rod fixedly disposed on the first chain plate 1. The shaft 33 and the mounting post 34 fixedly mounted on the second chain plate 30 are provided. The mounting post 34 has a rotating hole 35 that matches the shaft 33. The first chain plate 1 has a through hole 36 for the movement of the movable rod 32. A stop post 37 is fixedly mounted on one end of the movable rod 32 facing the second chain plate 30. The movable rod is an elastic rod. A first stop block 38 and a second stop block 39 are fixedly mounted on the outer circumference of the mounting post 34. The first stop block 38 and the second stop block 39 are spaced apart. The stop post 37 is located at... A stop post is positioned between the first stop block 38 and the second stop block 39. This stop post acts as a barrier during movement, and because the movable rod is elastic, it also provides cushioning and noise reduction. An arc-shaped mounting strip 40 is fixed to the first chain plate 1, spaced apart from the rotating shaft 33. Speed-reducing plates 41 are fixed to the upper and lower sides of the left side of the arc-shaped mounting strip 40. A noise-reducing plate 42 is fixed to the second chain plate 30, with the noise-reducing plate 42 facing the mounting post 34. An arc-shaped groove 43 is provided, and inclined plates A44 are fixedly connected to the noise reduction plate 41 at both ends of the arc-shaped groove 43. An inclined plate B45 matching the inclined plate A44 is fixed on the side of the arc-shaped mounting strip 40 away from the rotating shaft 33. An mounting assembly is set between the first chain plate 1 and the second chain plate 30, as well as the third chain plate 2 and the fourth chain plate 31. When the first chain plate and the second chain plate rotate, the movable rod contacts the first stop or the second stop, the mounting column contacts the speed reduction plate, and the inclined plate A contacts the inclined plate B, which plays a role in buffering and noise reduction.

[0025] The present invention is further configured such that the opposing surfaces of the first stop block 38 and the second stop block 39 are inclined, and a transition groove 46 is formed in the middle of the inclined surfaces of the first stop block 38 and the second stop block 39.
