According to the different structure types of the elastic bending belt 3, the following three embodiments can be specifically divided:

the first embodiment is as follows:

in the first embodiment, as shown in fig. 1 and 2, the elastic bending band 3 includes a first bending portion 31 bent in an S-shape. The bending of the first bending portion 31 into the S shape enables the elastic bending band 3 to have more bending surfaces, so that the retraction force of the elastic bending band 3 is increased, and the two nuts are more effectively limited from loosening continuously.

Specifically, one end of the first bending portion 31 may be connected to the first fastening target body 1, and the other end may be connected to the second fastening target body 2. When two nuts are loosened, the S-shaped first bending part 31 is gradually unfolded by the first fastening target body 1 and the second fastening target body 2, and when the S-shaped first bending part 31 is unfolded to a certain degree, the retracting force generated by the S-shaped first bending part 31 can limit the two nuts to be continuously loosened.

Or as shown in fig. 1, the elastic bending belt 3 may further include a first extending portion and a second extending portion, the first extending portion and the second extending portion extend linearly, one end of the first extending portion is connected to the first fastening target body 1, the other end of the first extending portion is connected to one end of the first bending portion 31, one end of the second extending portion is connected to the second fastening target body 2, and the other end of the second extending portion is connected to the other end of the first bending portion 31.

When the two nuts are loosened, the first fastening target body 1 and the second fastening target body 2 enlarge the opening of the U-shaped first bending part 31, and when the opening of the U-shaped first bending part 31 is enlarged to a certain extent or is completely opened, the retracting force generated by the U-shaped first bending part 31 or the length of the first bending part 31 can limit the two nuts from being continuously loosened.

As shown in fig. 3, the elastic bending strap 3 may further include a third extending portion and a fourth extending portion, the third extending portion and the fourth extending portion linearly extend, one end of the third extending portion is connected to the first fastening target body 1, the other end of the third extending portion is connected to one end of the second bending portion 32, one end of the fourth extending portion is connected to the second fastening target body 2, and the other end of the fourth extending portion is connected to the other end of the second bending portion 32.

Example three:

in the third embodiment, as shown in fig. 4, in order to timely limit the two nuts from loosening, the elastic bending band 3 includes a third bending portion 33 bent into an arc shape.

An arc shape, i.e. a shape of a part of a circle or an ellipse, as shown in fig. 4, the arc shape of the third bending portion 33 in the third embodiment may be a shape of a part of an ellipse.

Specifically, one end of the third curved portion 33 may be connected to the first fastening target body 1, and the other end may be connected to the second fastening target body 2. When two nuts are loosened, the first fastening target body 1 and the second fastening target body 2 stretch the arc-shaped third bending part 33, and when the first fastening target body is stretched to a certain degree, the retracting force generated by the arc-shaped third bending part 33 or the length of the first bending part 31 can limit the two nuts to be continuously loosened.

In some embodiments, the material of the elastic bending band 3 may be rubber, plastic, or the like having elasticity.

In some embodiments, as shown in fig. 1, the first fastening target body 1 includes a first connection ring 11 and a first indication portion 12 connected to the first connection ring 11, the first connection ring 11 is used for connecting with a nut.

When the nut takes place to become flexible, the nut drives first connecting ring 11 and rotates, and the user just can judge whether take place to become flexible through observing the position that first instruction portion 12 instructed.

Wherein the first indicator 12 may be triangular, drop-shaped, arrow-shaped, etc.

In at least one embodiment, as shown in fig. 1, the first indicator 12 has a triangular shape, and one side of the triangular shape is connected to the first connection ring 11.

When the nut is used, the first fixture block 111 is clamped with the outer circle surface of the nut, and the first fixture block 111 is arranged to simplify the structure of the first connecting ring 11, so that the first connecting ring 11 can be firmly connected with the nut.

Specifically, the inner circumferential surface of the first coupling ring 11 may have one, two, three, or more first latches 111. When the inner ring surface of the first coupling ring 11 has a plurality of first latches 111, the plurality of first latches 111 are uniformly distributed around the circumference of the inner ring of the first coupling ring 11.

In at least one embodiment, the inner circumferential surface of the first coupling ring 11 has a plurality of first latches 111.

In some embodiments, as shown in fig. 1, the second fastening target body 2 comprises a second connection ring 21 and a second indicator 22 connected to the second connection ring 21, the second fastening target body 21 being intended to be connected to another nut.

When the nut takes place to become flexible, the nut drives second instruction portion 22 and rotates, and the user just can judge whether take place to become flexible through observing the position that second instruction portion 22 instructed.

Wherein the second indicating portion 22 may be triangular, drop-shaped, arrow-shaped, etc.

In at least one embodiment, as shown in fig. 1, the second indicator 22 has a triangular shape, one side of which is connected to the second connection ring 21.

In some embodiments, in order to enable the second connection ring 21 to be firmly connected with another nut, as shown in fig. 1, the second connection ring 21 is sleeved outside the other nut, and the inner circumferential surface of the second connection ring 21 has a second latch 211 for being latched with the other nut.
