Description
Technical field
The utility model belongs to fastening standard piece field, relates in particular to a kind of novel anti-theft screw.
Background technique
The screw major part of selling in the market is that a cross or a word groove are set on screw head; Though this structure is simple; But the torsion that revolves tool is big inadequately, flat mouthful or the plum blossom mouth easy deformation of screw, and exist the article of fixed outdoor to be unclamped screw by the thief easily and stolen.
Summary of the invention
Be to solve the problem that existing technology exists, improve the antitheft degree of screw, improve the serviceability and the convenience of screw, design with a kind of must use special use revolve the rotatable anti-theft screw of tool.
To achieve these goals; The technological scheme that the utility model adopts is following: anti-theft screw; Comprise threaded screw rod and screw head, characteristic is that a word or cross recess on the screw head are made as arc groove, and described arc groove is a kind of in positive serpentine and the anti-serpentine; At the screw head center circular hole is set, Circularhole diameter is greater than the width of groove.
The arc groove of the utility model is stressed evenly, has improved the torsion of screw, and can prevent that one instrument and the instrument of pliers and so on from playing the screw threads of screwing, in order to prevent random dismounting, the equipment of suitable public place and the antitheft of parts; Such as Internet bar's computer housing, open-air equipment box, or the various cabinet that is exposed to the public place.Safeguard that for ease the utility model is furnished with the special-purpose tool that revolves, and can easily and effectively screw threads be risen with fastening, is convenient to the maintenance of equipment and device.
The beneficial effect of the utility model is: not only simple in structure, easy to make, improved the torsion of screw, and improve the serviceability and the convenience of screw, and can prevent effectively that fastened article are stolen because of withdrawing from screw.
