Described push-pull device at fixed is to be provided with the rotary screw being threaded with housing sidewall, is fixed with the sleeve pipe coaxial with rotary screw in inner walls, is built-in with the connecting link joining with bonding jumper at sleeve pipe.
Described push-pull device at fixed is to be provided with the fixed head that both sides relative to housing join, be connected to upper sliding plate and lower slider plate corresponding slip of fixed head upper and lower surface, upper sliding plate and lower slider the plate respectively corresponding earth's axis are connected in the two ends up and down of connecting link, be connected to the operating grip through housing sidewall with upper sliding plate or lower slider plate one side, described two bonding jumpers are respectively the upper sliding plate of setting and the annular metal bar in lower slider plate centre.
Described connecting link is semicircular gear, is engaged with adjusting gear with semicircular gear, and adjusting gear and operating grip join.
Below described plumb bob, be provided with damper and damping adjusting knob.
The utility model is in the time of levelling staff or mark post run-off the straight, contact with becket by tinsel, trigger alarm circuit is realized and being reported to the police, monitoring accuracy is to drive two symmetrical bonding jumpers that form becket to control by push-pull device at fixed, regulate the size of becket to adjust the spacing of tinsel and becket, in real time automatic capturing levelling staff plumbness and and alarm, not only resolution, precision and reliability are high, also can effectively improve the work efficiency of measurement of the level.
