In 71, and gland 76 is placed, is caught in anti-dropout slotting 75.Pedestal 71 is with gland 76 for wrapping up bulb 72 so that 72 energy of bulb
Easily it is freely rotated inside it；The effect of anti-dropout slotting 75 is to be neither easy to take off after making bulb 72 be mounted in gland 76
It falls, and can be freely rotated.
When crust breaking acts, pilot control valve body 3 is opened, so that the epicoele 84 of cylinder is entered high pressure gas, piston 9 is in high pressure
Moved end 21 is pressed by the elastic force for the first spring 22 for overcoming falling stop plunger 2 under the action of gas, piston 9 drives piston rod
91, sensor connecting rod 7 starts to move downward together, while sensor connecting rod 7 drives the drawstring 55 of stay wire displacement sensor 5
Move together, drawstring 55 be further driven to line wheel 54, rotation axis 53 and Flywheel disc 56 overcome fastening clockwork spring 57 elastic force do it is suitable
Hour hands rotate, and Flywheel disc 56 is in rotary course, when a through-hole 561 and photoemitter 562, photelectric receiver 563 are located at together
When on one straight line, the signal that photoemitter 562 is sent out receives and sends a pulse signal by photelectric receiver 563, and every
By a through-hole 561, photelectric receiver 563 sends a pulse signal, and the pulse signal that photelectric receiver 563 is sent is outer
Portion's controller is received and is counted, outside the umber of pulse that photelectric receiver 563 is received Flywheel disc corresponding with adjacent through-holes 561
All arc length are multiplied, you can obtain the pull-out length of drawstring 55（The displacement for the piston being connect with drawstring 55）.When pressure shell cylinder retracts,
Under the resilient force of fastening clockwork spring 7, line wheel 4 and Flywheel disc 6 is driven to rotate counterclockwise by rotation axis 3, drawstring 5 is received
It returns.In the present embodiment, the effect of isolating seal bearing 2 be support rotating axis 3 and isolation signals conversion storehouse 12 and line wheel storehouse 11 it
Between greasy dirt so that photoemitter 62 and photelectric receiver 63 can work normally, and externally output is intermittent for photelectric receiver 63
Pulse electrical signal.
