Device for measuring depth of outer ring screw hole of wind power locking disc

The utility model discloses a wind power locking disc outer ring screw hole depth measuring device comprising a measuring rod, the outer side surface of the measuring rod is uniformly provided with scale marks, the bottom end of the measuring rod is provided with a thread head matched with a wind power locking disc outer ring screw hole, the whole thread head is in a straight cylinder shape, and threads are arranged on the surface of the whole peripheral side of the thread head. The overall straight cylindrical thread head is matched with the measuring rod to measure the depth of the wind power locking disc outer ring screw hole, the lower surface of the thread head is a plane, and threads on the outer side of the thread head are arranged on the whole peripheral side surface from top to bottom, so that rotation is stopped when the thread head is screwed into the bottom hole without threads, and the depth of the wind power locking disc outer ring screw hole is measured. The problem that measurement is inaccura
