The device is installed in the fire escape through the frame 1. When people escape from the fire escape, they control the clamping device 7 on the right to release the hand-held cutting machine 10, and then use the hand-held cutting machine 10 to cut off the lock on the fire escape door. , and then open the anti-access door to escape, so that it does not hinder people's escape. When the door and window glass 15 needs to be broken, people control the left clamping device 7 to release the L-shaped cylinder 11, and then hold the L-shaped cylinder 11. The cylinder block 11 makes the suction cup 14 suck on the door and window glass 15, and then rotates the first knob 3 to move down to compress the air. The air in the compressed gas cylinder block 2 is sprayed into the L-shaped cylinder block 11 through the air pipe 5, and then pushes and strikes The block 12 moves backward rapidly to break the door and window glass 15 . In this way, the door and window glass 15 can be broken quickly, thereby saving time. At this time, the third compression spring 13 is compressed. When the door and window glass 15 is broken, people stop turning the first knob 3, under the action of the third compression spring 13, the striking block 12 is reset forward, and people can break the door and window glass 15 completely to escape.

Initially, the second compression spring 77 is in a compressed state. People put the hand-held cutting machine 10 between the two clamp bars 71 on the right side, and then push the push block 73 on the right side backward, the first compression spring 74 on the right side is compressed, and the push block 73 on the right side moves backward Drive the right clamping rod 71 to close inwardly, and clamp the handheld cutting machine 10. When the right push rod 78 corresponds to the right first slot 75, under the action of the right second compression spring 77 , the push rod 78 on the right moves to the left and gets stuck into the first slot 75 on the right, and the push block 73 on the right is fixed, and people can stop pushing the push block 73 on the right, and then repeat the above operation to make the L-shaped The cylinder block 11 is sandwiched between the two clamping rods 71 on the left side. When people escape from the fire escape, they hold the hand-held cutting machine 10, then pull the pull ball 710 on the right side forward, and drive the push rod 78 on the right side to move to the right through the steel wire 79 on the right side, and the second compression on the right side The spring 77 is compressed, when the push rod 78 on the right moves out of the first slot 75 on the right, under the action of the first compression spring 74 on the right, the push block 73 on the right resets forward, driving the The clamp bar 71 is opened outward, and the hand-held cutting machine 10 is released, and people can stop pulling the pull ball 710 on the right side, and then use the hand-held cutting machine 10 to cut off the lock on the fire escape door, and then escape. When the 15 is broken, people repeat the above-mentioned operations to release the L-shaped cylinder 11 from between the two clamp bars 71 on the left side.

People turn the first knob 3 to move down to press the air, and the valve core 18 blocks the L-shaped cylinder 11, so that the air cannot enter the L-shaped cylinder 11. After pressing the air, people pull the handle 19 forward, the first The torsion spring 20 is twisted and rolled, and the handle 19 swings forward to push the valve core 18 to move forward, opening the L-shaped cylinder 11, and the air in the compressed gas cylinder 2 is discharged into the L-shaped cylinder 11 through the air pipe 5, and then Push the hitting block 12 to move backwards to hit the door and window glass 15. At this time, the fourth compression spring 17 is compressed, and people release the grip 19. Under the action of the first torsion spring 20, the grip 19 moves backward. Swing, under the action of the fourth compression spring 17, the valve core 18 is reset back to block the L-shaped cylinder 11, and people pull the handle 19 forward again. 15 is knocked, so that the door and window glass 15 of different materials can be broken. When the window glass 15 is broken, people release the grip 19.

Initially, the fifth compression spring 22 is in a compressed state, and the second torsion spring 25 is twisted. When the suction cup 14 is sucked on the door and window glass 15, the second cylinder 21 is in contact with the door and window glass 15. When the door and window glass 15 is broken, people turn the second knob 28180 degrees, which drives the hook 26 to rotate 180 degrees, and the trigger rod 23 Released, under the action of the fifth compression spring 22, the trigger rod 23 moves backward, driving the special-shaped claw 24 to move backward. When the special-shaped claw 24 moves out of the second cylinder 21, under the action of the second torsion spring 25 , the special-shaped claws 24 are opened outward, and the door and window glass 15 is completely broken, so that the door and window glass 15 can be completely broken quickly.

The safety pin 4 can hold the first knob 3 to prevent the first knob 3 from being detached from the compressed gas cylinder 2 . When it is necessary to compress the gas, people can pull out the safety pin 4 .
