The utility model discloses a full -automatic cement electric pole mechanics amount of deflection detector includes a displacement sensor and the 2nd displacement sensor, and it installs the both endsin the pole pile foundation respectively for detect the displacement signal at pole pile foundation both ends respectively and convey to the treater, add lotus transmission, it is installed and linksto each other in the top of pole and with the treater for at the in -process of measuring pole amount of deflection, go on step by step with the lotus, just every grade with getting into between preset's the quiet stopping time after carrying on one's shoulder or back the completion to the pole, between preset's the quiet stopping time, the treater is mended the lotus and is surely carried on one's shoulder or back in predetermineeing error range automatically carry out the automation with lotus transmission, the load transducer dynamometer, it is with continuous with lotus transmission for detect and add lotus transmission conveying to the treater with the lotus value the pole, the amount of deflection sensor for detect top of electric pole's displacement signal and convey to the treater, the treater obtains the maximum defluxion and the output of pole according to received information and maximum defluxion formula.
