wheel (28) abuts against the supporting shaft (27) to rotate, the universal wheel (28) is enabled to prop up the base (1), the universal wheel (28) can roll on the ground through the universal wheel (28), a cavity is arranged in the base (1), the guiding triangular block (26) abuts against the universal wheel (28) to enable the universal wheel (28) to prop up the base (1), when the guide triangular block (26) moves to the outer end of the moving stroke, the control mechanism (8) is triggered to settle the case (3) in the cavity, other parts except the top of the case (3) are isolated from air, the universal wheels (28) move to enable the universal wheels to escape from a fire scene, meanwhile, the electromagnetic valve (74) and the driving fan (72) in the fireproof mechanism (7) are controlled to operate, the electromagnetic valve (74) is opened, compressed dry powder in the compression box (71) is sprayed out, the compressed dry powder is stirred and dispersed by the driving fan (72) and then uniformly sprayed onto the top cover of the case (3), and the compressed dry powder cannot enter the case (3) because the case (3) is wholly settled in the cavity, meanwhile, the flame in the upper space of the case (3) is extinguished, the case (3) is effectively prevented from catching fire, and further diffusion of the fire is avoided.
