Description
Technical field
The utility model belongs to hardware-joint field, is related to nail class product, especially a kind of screw for being easy to positioning.
Background technology
Screw is one of hardware-joint common in people's daily life, in various case, cabinet, the framves for needing to be connected
And other items on be all essential accessory.It is existing but the screw selection for some specific positions has special requirement
Standard screws can not meet needs, the existing screw position narrow and small in operating space is difficult to pre-install, and then causes
Installation difficulty, and its fixed installation is also difficult to realize using conventional screwdriver or spanner.
Utility model content
The purpose of this utility model is in place of overcome the deficiencies in the prior art, there is provided one kind positioning is simple and reliable, applicable
Property screw that is wide, being easy to positioning easily to operate.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of screw for being easy to positioning, including the head of a nail, screw rod and screw thread, a spiral shell is vertically formed with axial one end of the head of a nail
Bar, screw rod middle part are formed with screw thread, it is characterised in that：The screw rod is multi-diameter shaft screw rod, specifically, the screw rod away from the head of a nail is another
End face is coaxially formed with an extension screw rod, and the diameter of the extension screw rod is less than screw rod, is easy to insert the screws into progress in prefabricated screw
Prepackage positioning, one group of extension rod screw thread is formed with extension screw rod, is positioned for attaching nut.
Moreover, to be formed with annular chamfer domatic for the link position of screw rod and the head of a nail；Extend the link position system of screw rod and screw rod
There is chamfering section to carry out transition connection, light bar segment is left in the domatic both sides of the chamfering.
Moreover, the head of a nail is four-prism structure, and four sides of the four-prism are formed with square through hole.
Moreover, it is formed with one section of quadrangular in the middle part of the axial outer end of the extension screw rod.
The advantages of the utility model and good effect are：
The utility model is simple in construction, cost is cheap, is improved by structure and realizes its special function, can be convenient for pre-
Set position, be particularly suitable for use in narrow space when assembled, applicability is wide.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 is dimensional structure diagram.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, and following examples are simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of screw for being easy to positioning, the present embodiment is illustrated with direction shown in accompanying drawing 1 for convenience of description, including nail
Cap 1, screw rod 4 and screw thread 3, a screw rod is vertically formed with axial one end of the head of a nail, screw thread 3 is formed with the middle part of screw rod；
The link position of screw rod and the head of a nail is formed with annular chamfer domatic 2, the nail of the domatic embedded installation end face of the annular chamfer
Bore ends.
Innovative point of the present utility model is：
The screw rod is multi-diameter shaft screw rod, specifically, the screw rod other end away from the head of a nail is coaxially formed with an extension screw rod
6, the diameter of the extension screw rod is less than screw rod, is easy to insert the screws into prepackage positioning is carried out in prefabricated screw, moreover, in extension spiral shell
Bar is formed with one group of extension rod screw thread 7, is positioned for attaching nut；
The link position of extension screw rod and screw rod is formed with chamfering section 5 and carries out transition connection, and the domatic both sides of the chamfering are stayed
There is light bar segment, be easy to manufacture, and cost is relatively low.
For the ease of being used in crawl space, the head of a nail is four-prism structure, and four sides of the four-prism
Square through hole is formed with, spanner can be inserted from side and assembled.
For the ease of being operated in special space, one section of quadrangular 8 is formed with the middle part of the axial outer end of the extension screw rod,
It is easy to use wrench group.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with
Understand：Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modifications all be can
Can, therefore, the scope of the utility model is not limited to embodiment and accompanying drawing disclosure of that.
