When the technical scheme is used, the first screw rod penetrates through two objects to be connected, the abutting end abuts against one object, the other end of the first screw rod is screwed into the first nut, the two objects are connected, meanwhile, the second screw rod is continuously screwed into the second nut, the second screw rod extends into the annular groove of the first nut, then, the third nut is screwed, the third nut abuts against the first nut, and the locking force between the two objects is increased.
As a preferable mode of the present invention, a washer is sleeved on the second screw rod and is located between the third nut and the first nut.
According to the technical scheme, the pressing force of the third nut on the first nut is increased, so that the first nut is tightly attached to an object.
In a preferred embodiment of the present invention, a surface of the first nut facing the object is disposed in a zigzag structure.
By the technical scheme, the friction force of the surface of the first nut is increased, the screwing force of the first nut is also increased, and the locking force on an object is enhanced.
As a preferable scheme of the present invention, one end of the second screw rod extending into the annular groove abuts against the bottom of the annular groove.
By the technical scheme, the third nut can be sufficiently screwed and abutted to the first nut, and the situation that the third nut cannot be contacted is prevented.
As a preferable scheme of the present invention, the outer surfaces of the first screw and the second screw are provided with wear resistant layers.
By adopting the technical scheme, the wear resistance of the screw is improved.
In conclusion, the utility model has the following beneficial effects: when the connecting device is used, the first screw rod penetrates through two objects to be connected, the abutting end abuts against one object, the other end of the first screw rod is screwed into the first nut, the two objects are connected, meanwhile, the second screw rod is continuously screwed into the second nut, the second screw rod extends into the annular groove of the first nut, then, the third nut is screwed, the third nut abuts against the first nut, and the locking force between the two objects is increased. Through the arrangement, the overall structural strength of the bolt is enhanced, so that the two connected objects cannot be loosened, and the service life of the bolt is prolonged.
