[0023] The left side of the support plate 2 on the right side is connected to the shell 17 by bolts near the bottom, and the top and bottom of the shell 17 are both open. The left outer wall of the shell 17 is connected to the docking plate 16 by bolts near the top, and the top of the docking plate 16 is connected to the bottom of the operation box body 1 by bolts.
