Optical fiber verticality detection tool

An optical fiber perpendicularity detection tool relates to the field of machinery and comprises a central seat, an eyepiece seat and an objective lens seat are respectively arranged on two sides of the central seat, the objective lens seat is connected with an optical fiber seat, an insertion hole for accommodating an optical fiber to be inserted is arranged in the middle of the optical fiber seat, and an extrusion mechanism and a cutting mechanism are mounted in the optical fiber seat. The extrusion mechanism is connected with a driving mechanism, a marking mechanism is arranged in the optical fiber seat, optical fiber positioning can be achieved through the extrusion mechanism, whether fracture surface cutting is carried out or not is determined according to the fracture surface condition of optical fibers, people can be effectively reminded of qualified optical fibers through the marking mechanism, and confusion of the qualified optical fibers and undetected optical fibers is avoided. 一种光纤垂直度检测工具，涉及机械领域，包
