There is screw head, is equipped with several thread cavities vertically in the screw head, the thread cavity is opposite with screw rod to be arranged in parallel, the spiral shell
Line is intracavitary to be equipped with the locking holography bolt that can cooperate with thread cavity, and the locking holography bolt is arranged downward, described
Holographic bolt is locked to be detachably connected with thread cavity.
Preferably, the screw head cross section is regular hexagon or regular quadrangle, the screw head outer ring is equipped with can be with
With the outer wall of bayonet spanner cooperation.
Preferably, the screw head is equipped with several anti-skidding latches towards screw rod end surfaces.
Preferably, the thread cavity at least there are two, the thread cavity is described around the equidistant branch in screw head center
The holographic bolt of locking is equipped in thread cavity.
Preferably, the thread cavity upper end be equipped with can be with thread cavity chamber lid engaged therewith, the thread cavity chamber
Lid is detachably clamped with thread cavity.
Preferably, the length of the holographic bolt of the locking is less than the thickness of screw head, the locking holography bolt top
End is equipped with allen wrench bayonet or Phillips screwdriver bayonet or straight screwdriver bayonet, the locking holography bolt lower end are set
There is top.
Preferably, the screw rod, screw head, bone drill are coaxially disposed, the screw rod, screw head, bone drill are
Integrated formed structure.
A kind of anti-skidding tapping screw of antirust of the present invention the utility model has the advantages that the present invention by will be in the screw head of self tapping self-drilling screw
Thread cavity is set and locks holographic bolt, after screw-driving, can be tightened by the way that holographic bolt will be locked, lock holographic bolt
Top can withstand carrier surface, enhance frictional force, effectively prevent loosening.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
