Abstract

The invention discloses an antitheft self-tapping screw. The antitheft self-tapping screw comprises a nut, a stud and a sharp head. The nut is provided with a cross-shaped groove, a self-tapping thread is arranged on the stud, the nut and the stud are connected through a plurality of connecting pieces, and the number of the connecting pieces is three to six. When the antitheft self-tapping screw is used, a slot type screwdriver or a cross screwdriver is used for screwing the cross-shaped groove in the nut, and the sharp head and the stud are screwed into an object to be fastened; after the fastening process is achieved, external force is applied to enable the nut and the connecting pieces to be disengaged from the stud, and an antitheft effect is achieved.

Description

A kind of antitheft self-tapping screw
Technical field
The present invention relates to screw technical field, particularly relate to a kind of antitheft self-tapping screw.
Background technique
Screw is common fastening piece in manufacturing with industrial production in daily life, and its utilization is extremely extensive, and product specification has realized seriation and standardization, and its installation and removal can be used special instrument.But in some occasion, in order to make machine, equipment etc. reach certain antitheft requirement, in being convenient to installation, also must strengthen its fastening piece as the demolition difficulty of screw.
Summary of the invention
The present invention is in order to address the above problem, a kind of antitheft self-tapping screw is provided, can meet easy for installation, dismantle difficult requirement, the technological scheme adopting is: a kind of antitheft self-tapping screw, described antitheft self-tapping screw comprises nut, double-screw bolt and pointed head, and described nut is provided with cross recess, and described double-screw bolt is provided with Thread Forming TF, it is characterized by, described nut is connected by some connecting sheets with double-screw bolt.
Preferably, the quantity of described connecting sheet is 3 ~ 6.
Preferably, described antitheft self-tapping screw adopts Split type structure, and integrated double-screw bolt and pointed head adopt carbon steel material to make, and nut and connecting sheet adopt alloy material to make.
Preferably, the cylinder of described double-screw bolt is provided with through hole.
Owing to having adopted technique scheme, the present invention has following technique effect: the present invention in use, screw the cross recess on nut with a word or Phillips screwdriver, make pointed head and double-screw bolt be screwed into object to be tightened, on the cylinder of double-screw bolt, be provided with through hole, can use the hard long rod tool that diameter is suitable to apply rotating force through this through hole.Complete after fastening process, apply external force and make nut and connecting sheet depart from double-screw bolt, reach anti-theft effect.
Brief description of the drawings
