Fire resisting shutter capable of controlling slip speed and stopping falling at any time

The invention relates to the technical field of fire-fighting equipment, and discloses a fire resisting shutter capable of controlling slip speed and stopping falling at any time. The fire resisting shutter comprises a shutter box, wherein a rotating shaft is movably connected to the interior of the shutter box, the outer side of the rotating shaft is fixedly connected with a winding drum, a shutter is arranged on the outer side of the winding drum, the outer side of the rotating shaft and located on the right side of the winding drum is fixedly connected with a driving gear, the inner right wall of the shutter box is fixedly connected with a control box, and the left side of the control box is movably connected with a linkage shaft. Under the condition of power failure and fire, a brake is pulled apart after a fuse release device is blown, the self weight of the fire resisting shutter is reduced, a fixed rod and a centrifugal block are driven to rotate through the power generated whenthe fire resisting shutt
