Fixing magnetic box for building component

The utility model discloses a fixing magnetic box for building components, which belongs to the technical field of building components and comprises a magnetic box body, a fixing pressing plate, a mounting frame, a fixing mechanism and a deflection mechanism. The fixing mechanism and the deflection mechanism are used for driving the mounting frame and the fixing pressing plate to conduct angle deflection adjustment, the fixing pressing plate is pressed at the upper end of the building component side formwork through cooperation of the fixing mechanism and the deflection mechanism, and therefore the top of the building component side formwork is fixed and limited. The follow-up pouring production of the component can be more stable; and the height and the angle of the fixing pressing plate can be adjusted according to different side molds, and the device can be suitable for fixing the side molds with different heights and fixing angles, is wide in application range, meets the requirements under various conditi
