But in above scheme, after screwing in component, the head of screw can protrude from the surface of component screw, It is easy to tangle the things such as other component or clothing.
Summary of the invention
The object of the present invention is to provide a kind of split type screws, have after screwing in component, the head of screw will not protrude from The advantages of on the surface of component.
Foregoing invention purpose of the invention has the technical scheme that
A kind of split type screw, including head of screw and shank of screw, the head of screw and shank of screw split settings, the head of screw Top offers the groove in cross or linear type, and the head of screw is provided with L-shaped inserted block away from the side of groove, described The slot for inserted block insertion is offered in shank of screw, the side wall of the inserted block is abutted with the side wall of slot, the depth of the slot No more than the length of inserted block.
Implement above-mentioned technical proposal, inserted block is plugged in slot when use, so that the side wall of inserted block and the side wall of slot support It connects, then screwdriver corresponding with groove is inserted into groove, bit rotary screwdriver revolves shank of screw so that shank of screw rotation Enter to component, when being wholly embedded into component wait rotate to shank of screw, inserted block is extracted out of slot, then storage is good, Shank of screw will be flushed close to the end of head of screw with the surface of component in this way or the surface of slightly below component, the in this way screw exist After screwing in component, head of screw will not be protruded from the surface of component, so that being not easy to tangle other component or clothing etc..
Further, shallow slot is offered on the side wall of the slot, and the shallow slot is corresponded on the side wall of the inserted block and is provided with Convex block.
Implement above-mentioned technical proposal, when inserted block is inserted into slot, convex block will be with shallow slot grafting, so that inserted block is not by outer Under the action of power, itself it is not easy to be detached from out of slot, so during transportation, head of screw is not readily separated with shank of screw.
Further, the cross section of the head of screw is arranged in regular hexagon.
Implement above-mentioned technical proposal, in use, can be used after spanner clamps head of screw, rotary screw head is with by spiral shell Nail rod is screwed in into component, can improve the applicability of the screw by the spanner rotational fastener screw in this way.
Further, spiral protrusion is provided on the periphery wall of the shank of screw, on the periphery wall of the shank of screw Side respective protrusions positioned at protrusion offer helicla flute.
Implement above-mentioned technical proposal, when screwing in shank of screw to component, if component be it is wooden, with shank of screw Screw-in, can generate part sawdust, on the one hand the setting of helicla flute can accommodate sawdust, on the other hand for sawdust to be discharged, It can not be discharged to avoid because of sawdust, cause component to be squeezed and crack.
Further, an angle of the cross section setting triangular in shape of the protrusion, the protrusion is arranged away from screw rod end.
Implement above-mentioned technical proposal, reduces the contact area of protrusion with component in this way, revolved to reduce shank of screw The resistance that shank of screw is subject to when entering in component is easier to screw in shank of screw to component in this way.
Further, anti-skid chequer is provided on the periphery wall of the shank of screw.
Implement above-mentioned technical proposal, the setting of anti-skid chequer is so that shank of screw is not easy to take off out of component after screwing in component Out, it and is not easy sliding dead.
Further, the cell wall of the groove is provided with titanium alloy layer.
Implement above-mentioned technical proposal, the hardness of titanium alloy is high, so that groove is not easy when rotating the screw using screwdriver Deformation occurs.
Further, the shank of screw is provided with rubber ring on the periphery wall of screw head end.
Implement above-mentioned technical proposal, when shank of screw is threaded into component, rubber ring will be located at component and shank of screw Between, increase the frictional force between shank of screw and component, so that the screw is not easy to slide extremely, and is not easy to loosen.
In conclusion advantageous effects of the invention are as follows:
1. the screw is after screwing in component, head of screw will not be protruded from the surface of component, so that being not easy to tangle other Component or clothing etc.;
2. the hardness of titanium alloy is high, so that groove is not susceptible to deformation when rotating the screw using screwdriver;
3. rubber ring will increase shank of screw and portion between component and shank of screw when shank of screw is threaded into component Frictional force between part so that the screw is not easy to slide extremely, and is not easy to loosen.
