It is used in combination for big primary screw.Screw industrially bears vital task, as long as there is industry on the earth, then the function of screw is eternal
It is important.Screw is the joint invention in people's production and living over the past thousands of years, and from the point of view of application field, it is the first big of the mankind
Invention.
At present, screw generally comprises the body of rod, the threaded portion formed in the outer rim of the body of rod and formed in body of rod tail end
Conical head.Current screw thread when in use, because threaded portion is in bar shape, so perpendicular shape between threaded portion and workpiece, institute
When in use, relatively arduously, to be not easy to position, lock and unlock difficulty.
Utility model content
The purpose of this utility model is：In view of the shortcomings of the prior art, a kind of special-shaped screw is provided, the spiral shell of the screw
Rotation portion is different from the threaded portion of prior art, when in use easily positioning, and locks or unlock and be simple.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of special-shaped screw, including screw terminal and have with the integrally formed screw rod of the screw terminal, the end of the screw rod
There is spire, the spire is provided with the groove of a serpentine.
One kind as special-shaped screw described in the utility model is improved, and the width of the groove is 0.5 ~ 1.5mm, described
The depth of groove is 0.3 ~ 0.8mm.
One kind as special-shaped screw described in the utility model is improved, and the width of the groove is 1mm, the groove
Depth is 0.5mm.
One kind as special-shaped screw described in the utility model is improved, in addition to circular arc annular groove, the circular arc annular groove with
The spire connection.
As special-shaped screw described in the utility model one kind improve, the screw terminal include transition part and with the mistake
The head of portion's connection is crossed, the transition part has the rach slot of multiple array distributions, and the head has " ten " font groove.
The beneficial effects of the utility model are：The utility model includes screw terminal and integrally formed with the screw terminal
Screw rod, the end of the screw rod have spire, and the spire is provided with the groove of a serpentine.Spiral of the present utility model
Portion is provided with the groove of serpentine, has distinguished the threaded portion of prior art, and when in use, groove can be realized and quickly located, and
And locking or unblock are simple.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding to of the present utility model, forms one of the present utility model
Point, exemplary embodiment of the present utility model and its illustrate be used for explain the utility model, do not form to the utility model
Improper restriction.In the accompanying drawings：
Fig. 1 is one of structural representation of the present utility model；
Fig. 2 is the two of structural representation of the present utility model；
Fig. 3 is the three of structural representation of the present utility model；
Fig. 4 is the structural representation by locking member of the utility model matching.
Embodiment
Some vocabulary has such as been used to censure specific components among specification and claim.Those skilled in the art should
It is understood that hardware manufacturer may call same component with different nouns.This specification and claims are not with name
The difference of title is used as the mode for distinguishing component, but is used as the criterion of differentiation with the difference of component functionally.Such as logical
The "comprising" of piece specification and claim mentioned in is an open language, therefore should be construed to " include but do not limit
In "." substantially " refer in acceptable error range, those skilled in the art can be described within a certain error range solution
Technical problem, basically reach the technique effect.
In description of the present utility model, it is to be understood that term " on ", " under ", "front", "rear", "left", "right",
The orientation or position relationship of the instructions such as level " are based on orientation shown in the drawings or position relationship, are for only for ease of description originally
Utility model and simplifying describes, rather than instruction or implies that signified device or element must have specific orientation, with specific
Azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
In the utility model, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " Gu
It is fixed " etc. term should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
To be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, Ke Yishi
The connection of two element internals.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to restriction of the present utility model.
As shown in Fig. 1 ~ 4, a kind of special-shaped screw, including screw terminal 1 and screw rod integrally formed with screw terminal 12, screw rod 2
End there is spire 3, spire 3 is provided with the groove 4 of a serpentine.The width of groove 4 is 0.5 ~ 1.5mm, groove 4
Depth is 0.3 ~ 0.8mm.The width of groove 4 is 1mm by present embodiment, and the depth of groove 4 is 0.5mm.
In use, by the patchhole 6 of spire 3 of the present utility model so that the groove 4 of serpentine and the latch 7 in hole 6
Coordinate rotation, so as to realize locking, when needing unblock, rapidly screw terminal 1 need to only be reversely rotated and solution can be achieved
Lock, the utility model can realize fast positioning, and lock or unlock also rapid, simplification.
The utility model also includes circular arc annular groove 5, and circular arc annular groove 5 is connected with spire 3, and circular arc annular groove 5 has been provided with
Beneficial to the shaping of spire 3.
Preferably, screw terminal 1, which includes transition part 11 and the head 12 being connected with transition part 11, transition part 11, has multiple battle arrays
The rach slot 111 of column distribution, head 12 have " ten " font groove 121.
Some preferred embodiments of the present utility model have shown and described in described above, but as previously described, it should be understood that
The utility model is not limited to form disclosed herein, is not to be taken as the exclusion to other embodiment, and can be used for
