At this time, the first iron core and the second iron core are compositely fixed. By using a composite device, a variety of soft magnetic cores can be connected and fixed to form a composite iron core, so that the iron core has multiple properties, avoiding the situation where some equipment requires soft magnetic cores to have different properties in different usage conditions, but the soft magnetic core cannot be adapted, thereby improving the adaptability of soft magnetic cores.

By using the protective device, the first iron core and the second iron core can be shielded and protected to prevent the first iron core and the second iron core from being hit by external force and then damaged, thereby improving the service life of the first iron core and the second iron core.

[0017] Preferably, the size of the protective cover is adapted to the overall size of the first iron core and the second iron core.

[0018] The effect achieved by the above components is: by using a protective cover with a suitable size, the protective cover can better shield and protect the first iron core and the second iron core.

[0019] Preferably, one side of the bolt is in contact with a gasket, and one side of the gasket is in contact with the square tube.

At this time, the first core 1 and the second core 4 are compositely fixed. By using the composite device 2, a variety of soft magnetic cores can be connected and fixed to form a composite core, so that the core has multiple properties, avoiding the situation where some equipment requires the soft magnetic core to have different properties in different usage conditions, but the soft magnetic core cannot be adapted, thereby improving the adaptability of the soft magnetic core.
