The number of placement boxes 4 can be adjusted according to the number of welds, and then the bolt 42 is moved in the adjustment groove 44 to adjust the position of the placement box 4 according to the position of the welding point. Finally, the position of the placement box 4 is fixed by the hexagonal nut 43, so that the positioning point of the IGBT single tube can be fixed and adjusted. Then the IGBT single tube can be placed in the placement groove 41, and then the motor 35 is started to make the motor 35 start working.
