Roll the stator 24 for being provided be used cooperatively with floating cutting ferrule 23 obliquely.
In this application, captive nut includes nut body 1 and is fixed on the floating installation 2 in the outside of nut body 1, passes through
The screw thread 12 set in the screw 11 and screw 11 set in nut body 1, is spun by screw thread 12 with screw rod, so as to right
Parts are fixed, due to snapping piece of the floating installation 2 provided with acclivitous stator 24, the top of nut body 1 of linking closely
21st, the housing 22 of the bottom of clamp nut body 1 and the floating cutting ferrule 23 tilted down, will by stator 24 and floating cutting ferrule 23
Nut body 1, which is connected to, to be needed in part to be mounted, and by stress upward in stator 24 and floating cutting ferrule 23 to floating
Nut carries out clamping, when screw drive make it that captive nut translates, will by the freely swinging a low-angle of captive nut and
Offset, captive nut is really played its function of promoting load to be axially moved, ensure it under the equal screw thread pair accuracy of manufacture,
There is preferably transmission effect.
Preferable scheme is that the snapping piece 21 is provided with four altogether, and the snapping piece 21 is separately positioned on nut body 1
The both ends of left and right sides projection 13；Projection 13 is arranged among the both sides of nut body 1, and the projection 13 is along the both sides of nut body 1
Middle protruding, snapping piece 21 is just separately positioned on four angles between projection and nut body 1, so as to nut body
1 carries out clamping, makes captive nut be not easy to loosen.
Preferable scheme is, the floating cutting ferrule 23 is again lean-in after including along 90 ° of 22 bottom side downward bending of housing
First floating cutting ferrule 231 of bending obliquely, and be connected with the first floating cutting ferrule 231 and incline along the first floating cutting ferrule 231
The the second floating cutting ferrule 232 set obliquely.
Preferable scheme is that the floating cutting ferrule 23 can be moved upwardly or downwardly around the bottom side of housing 22.
The lower section side of housing 22 is provided with floating cutting ferrule 23 diagonally downward, and the floating cutting ferrule 23 fastens spiral shell with being used for
The housing 22 of maternal body 1 is the integrated design, after 90 ° of the side downward bending for the housing 22 of the bottom of clamp nut body 1
After connecting with the first floating cutting ferrule 231, the first floating cutting ferrule 231 again to the bottom of rugged housing 22, roll over diagonally downward by that side
Curved, floating cutting ferrule 23 is bottom up or move downward around housing 22, and being reached by 90 ° of bending makes floating cutting ferrule 23 float downward
Dynamic effect.
Preferable scheme is that the second floating cutting ferrule 232 and the end of stator 24 are provided with through hole 3, and through hole 3 is set
Putting can make to be flexibly connected required parts in floating installation 2, so as to adapt to the operating mode of more complexity.
Preferable scheme is that buffer mouth 25 is provided with the first floating cutting ferrule 231, and the side of buffer mouth 25 is set
There is buffer substrate tablet 26 diagonally downward, the buffer substrate tablet 26 is used to play the role of fastening to part；Pass through buffer mouth 25 and buffer substrate tablet 26
Setting, further supplementary function has been carried out to the effect that fluctuates of floating cutting ferrule 23, when the first floating cutting ferrule 231 and shell
When floating effect is preferable at 90 ° of 22 bending of body, buffer substrate tablet 26 can play a part of clamp nut body 1 and fastener, when first
When floating cutting ferrule 231 and bad floating effect at 90 ° of 22 bending of housing, floating action can be played with buffer substrate tablet 26, when screw
The axis of axis and nut not on one wire when, fluctuated a certain distance by floating cutting ferrule 23 and buffer substrate tablet 26,
So as to reach the effect that accurately can quickly carry out centering.

Dynamic device, by the screw thread set in the screw and screw that are set in nut body, spun by screw thread and screw rod, so that
Parts are fixed, because floating installation is provided with acclivitous stator, the snapping piece at the top of the nut body that links closely, tight
Gu the housing of nut body bottom and the floating cutting ferrule tilted down, are first put into enclosure interior by nut body, then the spiral shell that will link closely
The snapping piece of female bodies top carries out riveting, so as to be fastened to nut body；By stator and floating cutting ferrule by nut
Body, which is connected to, to be needed in part to be mounted, and by stress upward in stator and floating cutting ferrule to captive nut card
Tightly, when screw drive make it that captive nut translates, will freely swinging a low-angle and offset by captive nut, make floating
Nut really plays its function of promoting load to be axially moved, and ensures that it under the equal screw thread pair accuracy of manufacture, there is more preferable biography
Dynamic effect.
It can be moved upwardly or downwardly by floating cutting ferrule around housing bottom side, the floating cutting ferrule is with being used for clamp nut
The housing of body is the integrated design, for floating with first after 90 ° of the side downward bending of the housing of clamp nut body bottom portion
After dynamic cutting ferrule connects, the first floating cutting ferrule is again to the bending diagonally downward of that side of rugged housing bottom, and floating cutting ferrule is around housing
Bottom up or move downward, by bending, 90 ° reach the effect for making floating cutting ferrule be fluctuated；By buffer mouth and delay
The setting of punching, further supplementary function is carried out to the effect that fluctuates of floating cutting ferrule, when the first floating cutting ferrule and shell
When floating effect is preferable at 90 ° of body bending, buffer substrate tablet can play a part of clamp nut body and fastener, when the first floating card
When set and bad floating effect at 90 ° of housing bending, floating action can be played with buffer substrate tablet, when the axis of screw and the axle of nut
Line not on one wire when, fluctuated a certain distance by floating cutting ferrule and buffer substrate tablet, can be accurate so as to reach
The quick effect for carrying out centering.
Above is presently preferred embodiments of the present invention, not makees any formal limitation, every foundation to the present invention
