Problems solved by technology

[0002] At present, none of the elevator guide rail verticality testing instruments used at home and abroad adopts the corresponding mechanical fixing mechanism, and its data receiving devices are all implemented manually, so the stability is poor, and the measured data error is large; It is stipulated that the verticality embedded detection system of the elevator guide rail needs to measure the change of the small displacement, that is, at least within the range of 0.1mm, so the sensitivity of the selected detector must be high. In order to achieve the above-mentioned detection accuracy and mechanical structure fixing requirements, it is the research of the present invention Object
