in the technical scheme of the utility model, in order to ensure the stability of two monomer blocks 2 after combined screwing, the minimum fan-shaped radian of the monomer blocks 2 is 60 degrees, when the fan-shaped radian of the monomer blocks 2 is less than 60 degrees, the stability of the magnetic core 1 after combined screwing is reduced, and when the fan-shaped radian is less than 36 degrees, the stability of the magnetic core 1 is poor, and the stability is difficult to keep for a long time;
the single block 2 consists of a main layer 22 and an auxiliary layer 21, the main layers 22 of the main block 2A and the auxiliary block 2B are equal in thickness and fit to form a main layer ring, the auxiliary layers 21 of the main block 2A and the auxiliary block 2B are equal in thickness and fit to form an auxiliary layer ring, the inner diameter and the outer diameter of the main layer ring and the auxiliary layer ring are equal, and the upper end face and the lower end face of the main layer ring and the upper end face of the auxiliary layer ring are longitudinally overlapped and are same in shape and size;
