[0018] The fixed plate 7 is connected to a buffer structure on one side facing the middle of the noise reduction box 1, and the buffer structure includes a U-shaped fixing frame 11. The fixed plate 7 is fixedly connected to the two ends of the U-shaped fixing frame 11 on one side facing the middle of the noise reduction box 1. The inner sides of the two ends of the U-shaped fixing frame 11 are both recessed with a slide groove 12 with a trapezoidal cross-section. A movable plate 13 is slidably connected between the two ends of the U-shaped fixing frame 11. Slide blocks are connected to the matching slide grooves 12 at both ends of the movable plate 13.
