The working principle and the beneficial effects of the technical scheme are as follows: when the wind power from the outside blows on the suspension clamp or the wire for a long time, the nut 9 is inevitably loosened, the U-shaped fastening clamp block 2 and the suspension clamp main body 1 are separated to cause potential safety hazards to the suspension clamp, in order to avoid the situation, when the suspension clamp shakes, the nut anti-loosening assembly 11 can shake along with the U-shaped fastening clamp block, the rotating magnet 48 tightly attached to the side wall of the annular magnet 47 is in a suspension state, when no vibration occurs, the two circular permanent magnets in the rotating magnet 48 are in a magnetic field balance state, when one of the circular permanent magnets in the rotating magnet 48 generates acceleration due to the shaking from the outside, the side wall surrounding the annular magnet 47 is started to rotate, and the rotating magnet is always kept on the same plane with the annular magnet 47. When the circular rotating magnet 48 with certain inertial acceleration is close to the magnetic field range of the other rotating magnet 48, the magnetic field repulsion force acts between the two rotating magnets 48 to cause the other circular permanent magnet to generate acceleration, the two rotating magnets 48 continuously reciprocate and the position is changed rapidly until the two circular permanent magnets in the rotating magnet 48 recover the magnetic field balance state again under the friction action and the electromagnetic damping action of the rotating magnet 48 and the side wall of the annular magnet 47, and thus, the induction process of shaking the outside is completed once.
In the process, the ring-shaped magnet 47 drives the fixed shaft 46 to rotate and drives the outer ring 41 in the clamping sleeve ring 39 to rotate, because the first ratchet 42 on the inner ring 40 and the second ratchet 43 on the outer ring 41 tightly push against each other (as shown in fig. 10), the outer ring 41 can drive the inner ring 40 to rotate in the opposite direction (i.e. the fastening direction of the nut 9) through the second ratchet 43 and the first ratchet 42 while rotating, because the nut 9 is sleeved on the inner ring 40, a fastening force is given to the nut 9 to prevent the nut 9 from loosening, the structural design converts the energy of the shaking of the suspension clamp blown by external wind into the fastening force for the nut 9, and the nut 9 can be permanently fastened by a fastening force to prevent the nut 9 from loosening.
