It is full of tight fit, so that nut can not collapse out, effective clamping screw.
Nut structure are as follows: nut 2 includes nut body 21 and the locking female mounting portion 22 being made into integration with nut body.Spiral shell
Maternal 21 part of body is equipped with internal screw thread, and locking mother's mounting portion 22 is the slot structure 23 for accommodating locking mother.The slot structure 23 can
To be taper, top diameter is small, base diameter is big.
Locking parent structure are as follows: locking female 1 is equipped with notch seam 12, and notch seam 12 has folder with locking female axis direction
Angle, locking mother have shoulder 11.Notch seam 12 makes locking mother have certain elasticity, when notch 12 closure of seam locking mother can be packed into it is anti-
In loose mother's mounting portion 22.The width L of notch seam 12 can be set as 2mm.The angle α of notch seam 12 and axis is 10 ° to 25 ° degree.
Locking female 1 outer wall is the tapered surface being adapted to slot structure 23, and locking mother has shoulder 11, and 11 diameter of shoulder is equal to locking female installation
