The rotating wheel is arranged between the first circuit substrate and the second circuit substrate and connected with the box body through a hinge pin. The rotating wheel is connected with a rotary knob which is arranged on the outer side of the box body. The first circuit substrate is provided with a first tooth groove which is in threaded connection with the rotating wheel. The second circuit substrate is provided with a second tooth groove which is in threaded connection with the rotating wheel. The two side walls of the box body are provided with a first through hole and a second through hole respectively. The first circuit substrate is connected with the first through hole in a butted mode, and the second circuit substrate is connected with the second through hole in a butted mode. By means of the Z-shaped reversely-moving type printed circuit board, heat dissipating and electronic part assembling are facilitated, and after assembling, the Z-shaped reversely-moving type printed circuit board can be pushed back to the box body.
