When the glass shield 17 is damaged and the picture is moved, or when natural disasters such as earthquake occur, the fixed block 14 can generate instantaneous or anticlockwise offset, so that the rotating pin 41 at the upper end or the lower end is separated from the limit of the protrusion 50, the slide block 40 is loosened under the action of the sliding spring 39, the limit pull rope 38 is loosened, the left side or the right side or both sides of the return block 37 are loosened simultaneously, the induction plate 36 is not limited by stress, the steering pull rope 35 is not limited by stress, the steering belt wheel 71 is not limited by stress, the driven shaft 19 rotates left and right under the torsion spring, the blocking block 18 rotates, the blocking block 18 does not block the right air cavity 75 and blocks the left air cavity 74, in the process, the fixed block 14 moves leftwards under the action of the return spring 15 and retracts into the moving cavity 44, thereby causing the sliding piston 12 to move leftward, thereby exhausting the gas in the sliding chamber 47 into the right gas chamber 75, at the same time, the motor 34 works to drive the transmission shaft 33 to rotate, thereby driving the cam 32 to rotate, thereby pushing the push plate 30 to work, the push plate 30 reciprocates up and down under the action of the cam 32 and the moving spring 31, thereby driving the inflating piston 28 to reciprocate up and down through the push rod 29, and through the control of the first check valve 27 and the second check valve 28, so that the first air cavity 65 is continuously inflated, and at the same time, the air enters the second air cavity 66 from the first air cavity 65 and then enters the air cavity 75, so as to extend the hollow telescopic rod 76, and then the motor 34 is stopped after the moving block 11 with the picture frame 16 on the fixed block 14 moves upwards for a certain distance, so that the whole is stopped, and the picture is stored in the moving cavity 44 to be protected.

When the motor 34 is started after the contact is threatened to move the moving block 11 upwards to the top, the motor contacts the conversion pin 58 and pushes the conversion pin 58 upwards, the conversion pin 58 is limited by the fixed pin 57, the conversion pin 58 pulls the conversion pull rope 60 upwards, so that the control belt wheel 70 rotates, the steering shaft 20 is driven to rotate, the lower baffle plate 22 is driven to face a ten-o 'clock direction, the upper baffle plate 21 points to six o' clock direction, the first air cavity 65 is changed into an air suction state, the air in the hollow telescopic rod 76 is pumped out, the moving block 11 descends, after the moving block 11 descends and contacts the reset pin 54, the reset pin 54 moves downwards and pulls the fixed pull rope 55, the fixed pin 57 is driven to be separated from the limit of the conversion pin 58, the conversion pin 58 is reset downwards under the action of the conversion spring 59, the conversion pull rope 60 is loosened, and the control belt wheel 70 loses the stress limit, so that the steering shaft 20 is not restricted by force, and the steering shaft 20 is rotated again by the torsion spring, so that the first air chamber 65 is changed from the air-intake state to the air-charge state, and at the same time the first electromagnet 42 and the second electromagnet 43 are activated, causing the slider 40 to move to the right, pulling the limit pull cord 38, and thus the return block 37 upwards, thereby bringing the sensing plate 36 upward, via the connecting pin 78, thereby pulling the steering cord 35 upward, thereby driving the steering belt wheel 71 to rotate, driving the driven shaft 19 to rotate, driving the stop block 18 to reset clockwise, thereby allowing gas to enter the left gas chamber 74, and thus the sliding chamber 47, thereby pushing the sliding piston 12 to the right, thereby pushing the connecting rod 13 to the right and thus the fixing plate 14 to the right, and at this time, the first electromagnet 42 and the second electromagnet 43 are turned off so that the entire apparatus is reset.
