[0029] When the translation component needs to move the moving plate 2 towards each other or away from each other according to the size of the width of the circuit board, so that the circuit board is just fitted to the top position of the connecting belt 12 at both ends, the plug strip 13 can be rotated by starting the first motor 9, so that the two movable shafts 10 can be synchronously rotated under the connection of the plug strip 13 and one of the movable shafts 10 and the resistance of the plug strip 13 to the inner wall of the other movable shaft 10, so that the multiple mounting plates 14 are synchronously rotated under the connection of the connecting belt 12, and the two connecting belts 12 are moved, so that the circuit board can be transported from one side of the mounting base 3 to the other side of the mounting base 3 under the driving of the connecting belt 12 when the circuit board is placed at both ends of the connecting belt 12.
