The lower end of the support rod 104 is bolted to the first support plate 201. The support plate 104 is used to support the first baffle 101, the sound insulation plate 102, and the second baffle 103.
[0027] Furthermore, a slider 202 is welded to one side of the first support plate 201 in the support base 2, and a groove 203 is hollowed out on one side of the first support plate 201. A first slot 204 is hollowed out inside the first support plate 201, and insertion holes 205 are hollowed out at both ends of the first slot 204. The first support plate 201 is used to support the lower ends of the first baffle 101, the sound insulation plate 102, and the second baffle 103. The slider 202 is used to be movably connected in the sliding 203.
