A second abutting face is formed on the top wall in the movable groove, a lever fulcrum is formed at the transition position between the first abutting face and the second abutting face, a user presses the side, close to the movable groove, of the upper shell downwards, the lever fulcrum plays a fulcrum role, the side, close to the movable groove, of the upper shell swings downwards, and the side, away from the movable groove, of the lower shell warps upwards. The box body with the arrangement is simple in structure, the mode of opening the upper shell is simple, and time and labor are saved.
