[0028] When the automatic throwing mechanism is needed in operation, the inside of the storage tube 806 is filled with the terminating agent, and then the inside of the air bag 801 is filled with gas by using the second injection tube 802. When the operation is completed, the outer wall of the storage tube 806 and the inside of the sleeve 805 are sleeved with each other, so that the bottom of the pressing plate 8011 is attached to the outer wall of the air bag 801. The support tube 8 is placed transversely and inserted into the inside of the pressing tube 6, so that the outer wall of the storage tube 806 and the inside of the pressing ring 14 are sleeved with each other. The pressing ring 14 forms a closed loop, and when the overpressure gas is generated in the chemical reaction kettle 3, the pressing ring 14 is pushed to move from one side of the placing groove 12 to the other side of the placing groove 12, so as to press the spring 13.
