[0025] like Figure 1-2 As shown, the drive connecting rod 3 includes a sliding rod 31, a sliding sleeve 32, a push plate 33, and a connecting rod 34. The sliding sleeve 32 is fixedly mounted on the inner wall of the retaining ring 1. The sliding rod 31 is disposed within the retaining ring 1 and slidably fits within the sliding sleeve 32. One end of the sliding rod 31 extends through the retaining ring 1 and is fixedly connected to the push plate 33. One end of the connecting rod 34 is hinged to the middle portion of the side wall of the sliding rod 31, and the other end of the connecting rod 34 is hinged to the middle portion of the side wall of the chute cover 2. Sliding sleeves 32 are mounted on the inner walls of both sides of the retaining ring 1. Each sliding sleeve 32 slidably fits within a sliding rod 31. After extending from the retaining ring 1, the two sliding rods 31 are fixedly connected to the ends of the same push plate 33. A hydraulic buffer rod 9 is provided on the sliding rod 31. The hydraulic buffer rod 9 is arranged parallel to the sliding rod 31, and the buffer rod end of the hydraulic buffer rod 9 abuts against the side wall of the sliding sleeve 32. By providing the driving connecting rod 3 , the engineering equipment in the tunnel can be used to directly push the sliding rod 31 to open the chute cover 2 .

[0026] like Figure 2 As shown, a folded edge is formed on the side of the push plate 33 away from the retaining ring 1. The folded edge extends in the direction away from the retaining ring 1 and then bends toward the wellhead.
