By providing a rotating main disk 1 and a threaded screw 21, the fan 11 can be driven to rotate when the motor 22 is started to uniformly dissipate heat inside the box body 24. At the same time, through the threaded connection between the bevel gear cylinder 2 and the threaded screw 21, the bevel gear cylinder 2 can be driven to rotate when the rotating main disk 1 moves up and down, thereby driving the rack 8 to move up and down through the meshing connection between the bevel gear cylinder 2 and the lateral bevel gear 5 and the abutment between the cam 4 and the limit ring 7, and then through the meshing connection between the rack 8 and the auxiliary gear 10, the fan 11 is driven to swing up and down, which can dissipate heat at the edge position at multiple angles, further improving the stability and functionality of heat dissipation.
