Inductor rubber shell fixing device

The utility model relates to the field of inductors, in particular to an inductor rubber shell fixing device. The inductor rubber shell fixing device comprises a supporting frame, and a coil assembly is installed in the supporting frame. Each supporting frame is composed of two U-shaped frames in a butt joint mode, the sleeve plate is in a U shape, the two supporting frames slide in the sleeve plate, and one side of the sleeve plate is further integrally connected with a toothed plate; and the locking assembly is installed on the supporting frame, and the locking assembly is controllably inserted into the toothed plate. According to the inductor rubber shell fixing device, the two supporting frames are connected through the sleeve plate and can be stretched or contracted relative to the sleeve plate, so that the size of the internal space of the inductor rubber shell fixing device can be changed, the inductor rubber shell fixing device can be matched with more types of coil structures, the application range i
