Surely the lower end of the self tapping head of a nail is connected to, and the inside of the first auxiliary fixing member, first auxiliary fixing member are crossed in stud upper end
Including fixing rivet and washer, the fixing rivet symmetrically and evenly mounted on the lower end of washer, the washer upper end, which is fixed, to be connected
Connector is connected to, the self tapping head of a nail both sides are symmetrically installed with the second auxiliary fixing member, the second auxiliary fixing member bag
Firm banking and fixing bracket are included, the firm banking inner rotation is equipped with shaft, and the fixing bracket, which is fixedly connected on, to be turned
One end of axis is arranged with two mounting holes on the fixing bracket, and fixing bracket one side upper end is installed with grab,
The stud is equipped with screw thread.
Preferably, the both sides of the self tapping head of a nail are arranged with card slot.
Preferably, the washer is connected by connector with the self tapping head of a nail.
Preferably, the washer is annular shim, and middle part is set for hollow form.
Preferably, the upper end of the self tapping head of a nail is equipped with and screws slot.
Preferably, there are six the fixing rivet is set altogether, and it is evenly and symmetrically distributed on the bottom of washer.
Compared with prior art, the beneficial effects of the utility model are：
The anti-loosening self threading pin, the self tapping head of a nail are equipped with and screw slot, light can penetrated self threading pin using screwdriver
To inner, shaft packs up and trails convenient for support bracket fastened, and grab can be stuck in card slot when fixing bracket is packed up
Portion, so that fixing bracket is fixed on the one side of the self tapping head of a nail, mounting hole is worn after self threading pin fixes object using screw
Cross mounting hole so that self threading pin is fixed again with object, can effectively prevent fixed object vibration self threading pin from coming off, washer exists
It can be played during self threading pin fastening object and pad solid effect, fixing rivet is struck slightly after self threading pin fastening object, using external force
Beat self threading pin, six symmetrically arranged fixing rivets will be embedded into inner at this time, so as to but also self threading pin steadily
It is fixed on above the object of vibration, connector can fix washer and the self tapping head of a nail so that fixing rivet consolidates effect more
Protrusion, stud is equipped with screw thread, can be by light being fixed together steadily by two articles of self threading pin.
