Abstract
The utility model relates to a looseness detecting device of a bolt and nut fastener. The looseness detecting device is mainly used for detecting whether the bolt and nut fastener looses or not and reading a signal sent by a sensor through a detector. When the fastener looses to enable a nut to rotate, a driving gear is driven to rotate, and accordingly a driven gear meshed with the driving gear is driven to rotate. When a region where a metal coating on the surface of the driven gear is located is rotated to the upper portion of a sensor installing groove, the signal sent by the sensor to the detector is blocked, and accordingly the looseness of the fastener can be detected. Therefore, whether the fastener looses or not can be automatically identified, labor is saved, the detection efficiency is improved, and risk existing in manual detection is avoided.
