Specific embodiment
To censure specific components as employed some vocabulary in the middle of description and claim.Those skilled in the art should
It is understood that hardware manufacturer may call same assembly with different nouns.This specification and claims are not with name
The difference claiming is used as distinguishing the mode of assembly, but difference functionally is used as the criterion distinguished with assembly.As logical
In the middle of piece description and claim, mentioned " inclusion " is an open language, therefore should be construed to " include but do not limit
In ".Description subsequent descriptions are to implement the better embodiment of the present invention, and so described description is to illustrate that the present invention's is typically former
For the purpose of then, it is not limited to the scope of the present invention.Protection scope of the present invention when regard the defined person of claims as
Accurate.
Below in conjunction with accompanying drawing, the present invention is described in further detail, but not as a limitation of the invention.Embodiment 1
As shown in Figure 1-2, integral type stop nut, including nut body 1 and cyclic spring stay 11, described annular
It is integral type structure that flexible locking piece 11 is arranged on nut body 1 upper end with nut body 1；Described cyclic spring stay 11
To the bending of nut body 1 threaded inner side, and form an annular channel 2 with nut body 1；Described cyclic spring locking
Piece 11 internal diameter is less than nut body 1 threaded portion internal diameter or described cyclic spring stay 11 and nut body 1 threaded portion
Dividing has slight dislocation axially or radially.
Preferably, as shown in figure 4, in order to prevent cyclic spring stay 11 camber during bending excessively, described
It is additionally provided with limited step combination 12 in annular channel 2.
Preferably, described limited step combination 12 is more than one semicircle step composition.
Preferably, described limited step combination 12 is the ring-shaped step composition of the complete ring-shaped step of whole piece or interruption.
Embodiment 2
It is with embodiment 1 difference, described cyclic spring stay 11 is provided with more than one bar shaped otch above
