When the utility model is used, the locking sleeve 2 is first placed above the nut 1, and then the positioning column 16 is inserted into the positioning groove 18, so that the magnetic column 17 and the iron column 19 are magnetically connected, and the connection between the nut 1 and the locking sleeve 2 is completed, which plays a role in facilitating the installation and removal of the locking sleeve 2; when the nut 1 needs to lock the part, the bolt is passed through the through hole on the part, and the nut 1 is screwed into the protruding part of the bolt, so that the pressure pad 5 is pressed on the part, and the nut 1 is tightened to squeeze the spring 4, and the spring 4 will squeeze the pressure pad 5, so that the pressure pad 5 is fixedly connected with the part. At this time, the spring 4 will give the nut 1 an elastic force, so that the thread of the nut 1 is pressed against the thread of the stud, which plays a role in preventing the nut 1 from loosening; turn the rotary The column 10 drives the bevel gear B11 to rotate, and the bevel gear B11 drives the bevel gear A8 to rotate, so that the turntable 6 and the vortex bar 7 rotate. When the vortex bar 7 rotates, the arc bar 9 will move along the trajectory of the vortex bar 7, so that the locking block 3 slides and presses on the stud. After tightening the rotating column 10, the locking block 3 can be fixedly connected to the stud, which plays a role in further preventing the nut 1 from loosening. In summary, the utility model has the beneficial effect of preventing the nut 1 from loosening, and solves the problem that the traditional nut 1 has poor anti-vibration effect. When the nut 1 is in a high-vibration working environment, the nut 1 will be vibrated for a long time, which may easily cause the nut 1 to loosen or even fall off, resulting in a poor fastening effect.

[0021] Preferably, the locking assembly includes a turntable 6 rotatably arranged inside the locking sleeve 2, vortex bars 7 and bevel teeth A8 fixedly arranged on the upper and lower sides of the turntable 6, an arcuate bar 9 fixedly arranged below the locking block 3, a rotating column 10, and a bevel tooth B11 fixedly arranged on the outside of the rotating column 10.
