The inflatable body 7 is arranged in a hollow cavity that passes through from top to bottom. The inflatable body 7 is sleeved on the outside of the puncture body 5 and the spring 6, and the inflatable body 7 is installed on the base 1 by screws. A copper ball 15 is provided on one side of the trigger rope 8, and the copper ball 15 is clamped between the fixed steel blocks 3 on both sides. The airbag 9 is connected to the inflatable body 7 by screws, and the gas cylinder 10 is installed on the inflatable body 7.

[0021] Preferably, two groups of the fixing steel blocks 3 are provided, and the two groups of fixing steel blocks 3 are symmetrically arranged on both sides of the bottom fixing hole 11 .

[0022] like Figure 2 、 Figure 4 As shown, the puncture needle body 5 includes a spike portion 16, a sealing portion 17, a limiting portion 18 and a fixing portion 19, and the spike portion 16, the sealing portion 17, the limiting portion 18 and the fixing portion 19 are connected in sequence.
