Abstract
The invention discloses a screw which comprises a screw head, a screw rod and a screw point. The screw head, the screw rod and the screw point are arranged in an integrated mode. The diameter of a rod body of the screw rod is gradually increased from the connecting portion, in contact with the screw point, of the rod body to the upper portion and outer threads are arranged at the outer side of the rod body. The screw point is composed of two mutually perpendicular strips and the width of the bottom of each strip is smaller than that of the top of the strip. The screw head is of a hexagonal structure and a cross groove is formed in the upper surface of the screw head. When the screw is used, due to the fact that the screw point of the screw is composed of the two mutually perpendicular strips and the width of the bottom of each strip is smaller than that of the top of the strip, the screw can enter an object conveniently and the screw head of the screw is of the hexagonal structure with the cross groove so that when the screw is screwed, the cross groove enabling screwing to be conducted rapidly can be selected for operation or the side edge, with the large action force, of the screw head can be selected for operation according to the requirements, and therefore the flexibility is improved.
Description
Technical field
The present invention relates to a kind of fastening piece, be a kind of screw with being specifically related to.
Background technique
Screw is a kind of common fastening piece, can play well the effect of connection according to himself structural feature.But while working as the tapped hole that used screw is comprised of wood materials over there, due to himself material properties of wood materials, it has certain stretchability, its aperture of the tapped hole of offering can dwindle, if time length is likely fallen by " annexation ", this be screw in the process screwed, its nail bar be difficult to enter in tapped hole.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of screw.
Technical solution of the present invention is achieved in that a kind of screw, comprises all-in-one-piece screw head, nail bar and nail tip are set; The shaft diameter of described nail bar up increases successively from itself and the contacted joint of nail tip, and at its arranged outside outside thread; Described nail tip is comprised of two orthogonal battens, and the width of every batten bottom all is less than the width at its top; Described screw head is arranged to hexagonal structure, and offers cross recess in surface thereon.
Further, described outside thread lower surface up is offset with respect to the nail bar, and outward-dipping inclined-plane is arranged to in its exterior edge face.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described screw of the present invention program is in the process of using, because the nail tip of its screw is comprised of two orthogonal battens, and the width of every batten bottom is less than the width at top, facilitated like this entering of screw, the screw head of screw is arranged to the cross recessed hexagonal structure simultaneously, can select according to demand like this cross recess effect that can screw fast or the side effect that can use the larger screw head of active force in the process that screw is screwed, improve flexibility; On the other hand the outside thread lower surface is arranged to up be offset with respect to the nail bar, and outward-dipping inclined-plane is arranged to in its exterior edge face, facilitated so further screw to enter in tapped hole.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation that accompanying drawing 1 is screw of the present invention;
Wherein: 1, screw head; 2, nail bar; 3, nail tip; 4, outside thread; 5, batten; 6, cross recess.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Wherein said outside thread 4 lower surfaces up are offset with respect to nail bar 2, and outward-dipping inclined-plane is arranged to in its exterior edge face.
Screw of the present invention is in the process of using, because the nail tip 3 of its screw is comprised of two orthogonal battens 5, and the width of every batten 5 bottoms is less than the width at top, facilitated like this entering of screw, the screw head 1 of screw is arranged to the hexagonal structure with cross recess 6 simultaneously, the cross recess 6 that can select according to demand like this to screw fast in the process that screw is screwed is acted on or can be used the side effect of the larger screw head 1 of active force, has improved flexibility; On the other hand outside thread 4 lower surfaces are arranged to up be offset with respect to nail bar 2, and outward-dipping inclined-plane is arranged to in its exterior edge face, facilitated so further screw to enter in tapped hole.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a screw, comprise all-in-one-piece screw head, nail bar and nail tip be set; It is characterized in that: the shaft diameter of described nail bar up increases successively from itself and the contacted joint of nail tip, and at its arranged outside outside thread; Described nail tip is comprised of two orthogonal battens, and the width of every batten bottom all is less than the width at its top; Described screw head is arranged to hexagonal structure, and offers cross recess in surface thereon.
2. screw according to claim 1 is characterized in that: described outside thread lower surface up is offset with respect to the nail bar, and outward-dipping inclined-plane is arranged to in its exterior edge face.
