The utility model discloses a kind of special-shaped screw, it includes：First body of rod, second body of rod, coiled hair, gathering sill, annular groove and oil-through hole；First body of rod is arranged on coiled hair upper surface；Second body of rod is arranged on coiled hair lower surface；First body of rod is provided with annular groove；Second body of rod lower end is provided with screw thread；Any side of second body of rod opens up a gathering sill；The special-shaped screw center opens up an oil-through hole.The utility model simple structure, reasonable in design, installation and removal are convenient easy, with enough intensity and good manufacturability, and low cost of manufacture.
Description
Technical field
The utility model is related to locking part field, more particularly to a kind of special-shaped screw.
Background technology
Screw in the market starts groove profile because driving angle is more than 0 degree, easily produces radial load, causes torsion
Loss, causes screwdriver and screw groove profile mesh degree defective tightness, and transmission moment values reduce；And groove profile inwall has cone
Degree, face loading power is less than normal, and screwdriver can be caused easily to be skidded in the turn of the screw again, and damaged screws start groove, and then occur
The serious consequence that screw can not be screwed into or can not back-out.Also it is exactly just to be difficult oily asking of back-outing and can not come the twist-on time
Topic.
Utility model content
The utility model is solved mainly solving the technical problems that provide a kind of special-shaped screw, its is reasonable in design, simple structure
Screw twist-on in the prior art of having determined is of long duration not easy to remove and the problem of oil strain can not be crossed by screw.
In order to solve the above technical problems, the technical scheme that the utility model is used is to provide a kind of special-shaped screw, its
Including：First body of rod, second body of rod, coiled hair, gathering sill, annular groove and oil-through hole；First body of rod is arranged on coiled hair
On surface；Second body of rod is arranged on coiled hair lower surface；First body of rod is provided with annular groove；Second body of rod
Lower end is provided with screw thread；Any side of second body of rod opens up a gathering sill；The special-shaped screw center opens up an oil-through hole.
Preferably, first body of rod, second body of rod and coiled hair are one overall；
Preferably, the annular groove has two；
Preferably, the coiled hair is hexagonal；
Preferably, the oil-through hole is through hole, through whole special-shaped screw.
The beneficial effects of the utility model are：The utility model simple structure, reasonable in design, installation and removal are convenient to be held
Easily, with enough intensity and good manufacturability, low cost of manufacture；Lubrication can be imported by gathering sill when the twist-on time is long
Oil reduces friction, while oil-through hole oil moistening can also reduce to pipe fitting and rub excessively.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of special-shaped screw of the utility model；
The mark of each part is as follows in accompanying drawing：1st, first body of rod；2nd, second body of rod；3rd, coiled hair；4th, gathering sill；5th, annular is recessed
Groove；6th, oil-through hole.
Specific embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model
Define.
Accompanying drawing 1 is referred to, the utility model embodiment includes：First body of rod 1, second body of rod 2, coiled hair 3, gathering sill 4, ring
Connected in star 5 and oil-through hole 6；First body of rod 1 is arranged on the upper surface of coiled hair 3；Second body of rod 2 is arranged under coiled hair 3
On surface；First body of rod 1 is provided with annular groove 5；The lower end of second body of rod 2 is provided with screw thread；Second body of rod 2
Any side opens up a gathering sill 4；The special-shaped screw center opens up an oil-through hole 6.
It is further that first body of rod 1, second body of rod 2 and coiled hair 3 are one overall；
It is further that the annular groove 5 has two；
It is further that the coiled hair 3 is hexagonal；
It is further that the oil-through hole 6 is through hole, through whole special-shaped screw.
The utility model simple structure, reasonable in design, installation and removal are convenient easy, with enough intensity and good
Manufacturability, low cost of manufacture；Can import lubricating oil by gathering sill 4 to reduce friction when the twist-on time is long, while oil-through hole 6
Pipe fitting reduction can also be rubbed oil moistening excessively.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
