The fixed column 8 is connected with the bottom plate 9 and the top fixing frame 10; two ends of the fixing column 8 are fixed on the bottom plate 9 and the top fixing frame 10 in a welding mode. Electrode pole fixing holes 11 are formed in corresponding positions of the top fixing frame 10 and the bottom plate 9. The first boat board 1-1 and the second boat board 1-2 are generally rectangular, and therefore the rectangular top fixing frame 10 can better fix the first boat board 1-1 and the second boat board 1-2. The fixed column 8 is distributed with grooves matched with the first boat board 1-1 and the second boat board 1-2, so as to further provide a space for stabilizing the first boat board 1-1 and the second boat board 1-2, and avoid the situation that the connection of the square boat is unstable and the frame is scattered. The specific groove is a concave groove, the height of the groove is adapted to the thickness of the first boat plate 1-1 and the second boat plate 1-2, and the first boat plate 1-1 and the second boat plate 1-2 can be conveniently inserted into the square boat frame 7.
