[background technique]
Screw is common in mechanical, electric appliance and building etc., and general material is metal or plastic cement, and cylindrical, surface is carved with
Concave-convex ditch is known as screw thread, and the main function of screw is two objects of engagement, or fixes the position of an object, and screw is usual
Can arbitrarily remove or again panelling without damaging its efficiency.The top diameter of general screw is larger, common are round, rectangular or just
Hexagon can rotate screw with spanner, if top is circle, top face also has rill, side if top is regular hexagon
Just screw is rotated using corresponding screwdriver.The most common rill has "-" type, cross and rectangular, also there is other shapes
Shape, self drilling tapping screw are one of screws, and this screw with drilling tail point, gain the name as spiral bit, assembling by tip
When screw can voluntarily drill out center Confucius, followed by the threaded portion closed on, self tapping squeezes and cuts out and match therewith in hole on carrier
The screw thread of conjunction, therefore referred to as self-drilling self-tapping screw.The anti-theft performance of existing self-drilling self-tapping screw is poor, and criminal passes through spanner very
It is easy just to back out, safety is low, be easy to cause property loss, after screw long-time use, due to vibration etc., is easy pine
Dynamic, connection is unstable, dangerous.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of handware anti-loose anti-theft self-drilling self-tapping is proposed
Screw can be improved the anti-theft performance of screw and the anti-loosening performance of screw.
To achieve the above object, the invention proposes a kind of handware anti-loose anti-theft self drilling tapping screw, including screw rod,
Bone drill, screw head, tightening portion, the screw rod are cylindrical type, and the screw rod lower end outer surface coiling protrusion is equipped with outer spiral shell
Line, the screw rod lower end are equipped with bone drill, and the bone drill is an integral molding structure with screw rod, on the screw rod
End is equipped with screw head, and the surrounding of the screw head exceeds screw rod, and the screw rod and screw head Relative vertical are arranged, the screw head
Upper end is equipped with tightening portion, and the tightening portion and screw head Relative vertical are arranged.
Preferably, the tightening portion includes that the relatively small connection of diameter twists into two parts portion and for pulling with what spanner was clamped
Hand bayonet part, the connection are twisted into two parts portion and are fixedly connected with screw head, and the tightening portion top is equipped with spanner bayonet part.
Preferably, it is described the connection of tightening portion is twisted into two parts twisted into two parts between portion and screw head required torsion be greater than by from bore
Tapping screw tightens required torsion.
Preferably, the spanner bayonet part can be allen wrench bayonet, Phillips screwdriver bayonet or a word spiral shell
Silk knife bayonet.
Preferably, the screw head is the collar plate shape of smooth outer surface, the screw head is equipped with towards screw rod end face
Several anti-skidding latches.
Preferably, the screw rod, bone drill, screw head, tightening portion are coaxially disposed.
Preferably, the screw rod, bone drill, screw head are an integral molding structure.
A kind of handware anti-loose anti-theft self drilling tapping screw of the present invention the utility model has the advantages that the present invention by by self-drilling self-tapping
Tightening portion is arranged in screw upper end, can continue to turn by tightening portion by screw-driving, after tightening up to twisting into two parts tightening portion,
Screw screw head surface after twisting into two parts is smooth, and no impetus goes out screw lemon, and anti-theft performance is outstanding, the antiskid card of screw head lower end
The frictional force between screw and equipment can be enhanced in tooth, enhances anti-loosening performance.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
