There is no difference in principle between high-frequency transformers and low-frequency transformers. However, due to the different frequencies of high and low frequencies, the iron cores used in transformers are different. Low-frequency transformers generally use silicon steel sheets with high magnetic permeability, and they need to be assembled after the low-frequency transformer parts are produced.

[0011] Furthermore, a first fixing screw is inserted into the connecting block, and the first fixing screw is threadedly connected to the winding seat.

[0012] Furthermore, the first fixing screw adjustment portion is a hexagonal structure, and an adjustment slot is provided at the first fixing screw adjustment portion, and the adjustment slot is a hexagonal slot-shaped structure.

[0013] Furthermore, a protective cover with a square cover-shaped structure is clamped on the two clamping seats, and two second fixing screws are threadedly connected to the protective cover, and the two second fixing screws are threadedly connected to the two clamping seats respectively.

[0014] Compared with the prior art, the utility model has the following beneficial effects:
