Powder magnetic core

The utility model discloses a powder pressing magnetic core. Including a base, the upper surface of the base is fixedly connected with one end of a framework. The framework is in a spiral shape. The other end of the framework is fixedly connected with a guide rail; the guide rail and the framework are the same in structure. The guide rail is communicated with the framework; the inner surface of the guide rail is slidably connected with a powder pressing magnetic core. The powder pressing magnetic core is spiral, and a gear groove is formed in the upper surface of the powder pressing magnetic core. A through groove is formed in the position, corresponding to the gear groove, of the upper side wall of the guide rail. An adjusting device is arranged at the upper end of the through groove; themagnetic core is arranged to be spiral, so that the equipment does not occupy too much space and is not limited by external terrains while the length of the magnetic core is increased, the adjustingdevice is arranged, the ad
