A magnetic force fixing frame comprises a first window frame, a second window frame, a first fixing outer frame, a second fixing outer frame, an inlaid connecting plate and a window core. The first window frame comprises a first hinging frame, a first supporting frame and a first closed frame, and the second window frame comprises a second hinging frame, a second supporting frame and a second closed frame. The first fixing outer frame comprises a first window core fixing plate and a first window core clamping plate, and the second fixing outer frame comprises a second window core fixing plateand a second window core clamping plate. According to the magnetic force fixing frame, the first window frame, the second window frame, the first fixing outer frame, the second fixing outer frame, theinlaid connecting plate and the window core are arranged, the first window frame and the second window frame are used for containing the window core, the first fixing outer frame and the second fixing outer frame fix the window core into the first window frame and the second window frame through magnetic force correspondingly, the window core can be rapidly drawn out from the first window frame and the second window frame, and the effect of window core rapid dismounting and mounting is achieved.
