Packaging Paper is provided with packaging ring, middle part powder charge chamber is provided between packaging ring and end plate, medicine head is filled with the powder charge chamber of middle part；
The middle cylinder inwall epimere is provided with internal thread, and external screw thread is provided with interior cylinder outer wall, and internal thread is matched somebody with somebody with external screw thread
Close and set；Connection ring, middle cylinder top are provided between the top inwall of middle cylinder top outer wall and outside cylinder
Outer wall is fixedly connected with the top inwall of outside cylinder by connection ring, between the inwall of the outer wall of middle cylinder and outside cylinder
It is provided with and explosive is filled with drug-filling cavity, drug-filling cavity；Rubber stopper is provided with the interior cylinder, the two ends of rubber stopper are arranged at
It is provided with interior cylinder, in rubber stopper in two fairleads, fairlead and sets leaded, the two ends of lead is higher than interior cylinder
End face.
Optimization, above-mentioned safety blasting device is provided with some strip grooves on the outer surface of the outside cylinder.
Optimization, above-mentioned safety blasting device is provided with some exhaust holes on the rubber stopper.
The advantage of the invention is that the drawbacks of it can overcome prior art, reasonable in design novelty.The design of the application
It is provided separately with the medicine head of ignition by by the lead of ignition.When needing to ignite, inside is made by rotating inner part cylinder
Cylinder is moved in middle cylinder towards packaging ring, and lead is contacted after wearing out Packaging Paper with the medicine head of ignition, and two leads lead to
Medicine head burnup pilot combustion exploding wire after electricity, the explosive in drug-filling cavity that ignited after burning exploding wire burning is so that demolition set occurs
Blast.Such mode causes that lead is provided separately with the medicine head of ignition, is contacted by both when needing and igniting, and prevents quiet
Electricity, the interference of radio frequency electrical and stray electrical current and trigger early quick-fried accident, increased the security of demolition set.Strip groove is convenient
Outside cylinder ruptures in explosion time.Air drag when exhaust hole reduction interior cylinder is moved in middle cylinder.
