The column 143 is fixed to the fixing plate 142 and passes through the second through hole 1414 upward.

[0026] The second inner bracket 15 is also in an “n” shape, which is fixed on the bottom plate 12 and located between the upper plate 11 and the bottom plate 12 . The second inner bracket 15 is spaced apart from the first inner bracket 14 along the Y direction.

[0027] The two bridging blocks 16 are symmetrically arranged along the X direction and are located on the outer sides of the upper plate 11 and the side plate 13. The bridging blocks 16 include a horizontal portion 161 and an upright portion 162 extending downward from the inner end of the horizontal portion 161. The lower surface of the horizontal portion 161 is provided with two second sliding grooves 163 extending along the Y direction. The lower end of the upright portion 162 is fixedly connected to the end 120 of the bottom plate 12.
