Interior rivet nut tip 6, interior rivet nut tip 6 is just to the center of V-shaped groove 9；The interior outside of rivet nut tip 6 has screw thread, and by being engaged
The nut 5 of setting is removably secured in the cavity of outer rivet nut 1；The top of interior rivet nut 3 is by connecting key 4 and the inner edge phase of the outer head of a nail 2
Even, the top of interior rivet nut 3 is provided with the nail groove for coordinating screwdriver to use.
Preferably, described expanding plate 7 is plane platelet structures；The described quantity of expansion slot 8 is 2, set location
It is into 180 degree angle to be oppositely arranged.
Preferably, described expanding plate 7 is cross laminated structure；The described quantity of expansion slot 8 is 4, arranges position
It is set to and is mutually an angle of 90 degrees and is uniformly distributed setting.
In addition, interior rivet nut tip 6 of the present invention can be cone.Expanding plate 7 can be using iron plate, aluminium flake, hard
Any appropriate current material such as matter engineering plastic tablet makes.
Beneficial effects of the present invention：The automatic fastening screw of the present invention can be securely fixed in the interior of fixation body
Portion, the occasion often rocked in Jing is not susceptible to loose or dislocation, at the same it is identical with existing screw when using, tighten, ten
Divide convenient.

Specific embodiment
Refer to Fig. 1 to Fig. 4.
Embodiment 1：
The automatic fastening screw of the present invention, with hollow outer rivet nut 1, is provided with external screw thread, outside outside outer rivet nut 1
The top of rivet nut 1 is provided with the hollow outer head of a nail 2；Expanding plate 7 is provided with the cavity of outer rivet nut 1, the upper end of expanding plate 7 is provided with
V-shaped groove 9；Coordinate expanding plate 7 to be provided with expansion slot 8 in the side of outer rivet nut 1, expanding plate 7 is stretched from expansion slot 8 when expanding
Go out；Solid interior rivet nut 3 is additionally provided with the hollow structure of the outer head of a nail 2 and outer rivet nut 1, the bottom of interior rivet nut 3 has protrusion
Interior rivet nut tip 6, interior rivet nut tip 6 is just to the center of V-shaped groove 9；The interior outside of rivet nut tip 6 has screw thread, and by being engaged
The nut 5 of setting is removably secured in the cavity of outer rivet nut 1；The top of interior rivet nut 3 is by connecting key 4 and the inner edge phase of the outer head of a nail 2
Even, the top of interior rivet nut 3 is provided with the nail groove for coordinating screwdriver to use.Expanding plate 7 is plane platelet structures；Described expansion slot 8
Quantity is 2, and set location is into 180 degree angle and is oppositely arranged.Interior rivet nut tip 6 is cone.
During use, the present invention as assembled above is finished.The outer rivet nut 1 of the present invention is downwardly in nail, is used
In screwdriver is embedded in the nail groove on the top of rivet nut 3, rotation screw knife.There is external screw thread because outer rivet nut 1 is outer, rotate strength and pass through
Interior rivet nut 3 passes to connecting key 4, and Jing connecting keys 4 pass to the outer head of a nail 2 and outer rivet nut 1, you can outer rivet nut 1 is screwed into into nail.Outward
Rivet nut 1 is fully entered and can not continue after nail rotation, and now the spinning force of screwdriver is acted on connecting key 4, makes connecting key 4
Fracture, interior rivet nut 3 loses annexation with the outer head of a nail 2.Interior rivet nut 3 continues rotation under the spinning force of screwdriver, due to spiral shell
Female 5 positioning action, interior rivet nut 3 is gradually moved down and makes interior rivet nut tip 6 oppress the core of V-shaped groove 9, under forcing V-shaped groove 9
Recessed rupture.
After the recessed rupture of V-shaped groove 9, with heading into for interior rivet nut tip 6, the two side portions of expanding plate 7 open outer shifting, and from expansion
Open and stretched out in groove 8, form fixed thorn 10.Fixed thorn 10 is pierced into by fixed interior of articles, with the collective effect of the outer head of a nail 2 by outer nail
Body 1 is secured firmly in nail, and interior rivet nut 3 need not be removed or screw out.The outer external screw thread for arranging of outer rivet nut 1 can prevent outer
There is length travel in rivet nut 1；Fixed thorn 10 can prevent outer rivet nut 1 from rotating, and the two generation that cooperates is fixedly secured outer
The technique effect of rivet nut 1.Now the present invention will not be able to be removed again or extract, in the occasion that Jing often shakes, rocks, the present invention
It is not easy loose or dislocation.
Embodiment 2：
With embodiment 1, it is cross laminated structure that difference is described expanding plate 7 to the present embodiment major part；It is described
The quantity of expansion slot 8 be 4, set location is uniformly distributed setting to be mutually an angle of 90 degrees.
In use, the present embodiment main working process is with embodiment 1.Difference is cross after V-shaped groove 9 ruptures
The upper limb of expanding plate 7 of shape will form 4 fixed thorns 10 for being mutually an angle of 90 degrees distribution, and the fixation of external rivet nut 1 is more firm, in Jing
The outer rivet nut 1 of occasion often rocked will not occur fine rotation, and fixation body is more difficult loose or dislocation.
