Referring to Fig. 2, in a particular embodiment, the air bag 3 connect high pressure air rifle 11, institute with air valve 6 by high-pressure air pipe 7
Shock sensor 5 is stated to connect with sensor socket 8 by electrical signal line 9.It is arranged with outside the high-pressure air pipe 7 and electrical signal line 9
Sheath 10.
When specifically used, air bag 3 is deflated, Return spring 4 tenses lever arm 2, and lever arm 2 is put into stiff case 1.
Utility model device is put into drilling, connection high pressure air rifle 11 is that air bag 3 is inflated with air valve 6, and air bag 3 is gradually swollen after inflating
It is swollen, lever arm 2 is ejected, so that lever arm 2 is contacted and compresses hole wall, realize shock sensor 5 and hole wall rigid contact, then lock
Firmly air valve 6 measures；After being measured, air valve 6 is opened, is gradually tapered up after so that air bag 3 is deflated, lever arm 2 is in Return spring 4
It is recovered under pulling force effect in stiff case 1, takes out the present apparatus.
