Mouthful, and the first punch-pin for being provided with expansion rod tail end of first notch and the second notch and the second punch-pin mutually agree with, it is described swollen
Interior retainer is provided with the top of expander roll, the expansion rod afterbody is provided with thin folding neck, and the thin folding neck is connected with tailpiece, and the tailpiece passes through
Breaker bars are connected with rivet bar.
As a kind of preferred technical scheme of the utility model, the breaker bars fill for slice, and are uniformly connected to tailpiece
Between rivet bar.
As a kind of preferred technical scheme of the utility model, if the expansion rod is provided with dried layer internal lock circle, and interior retainer
Side is parallel with expansion rod side, if the rivet bar is provided with dried layer external lock circle.
As a kind of preferred technical scheme of the utility model, the rivet bar, expansion rod and tailpiece are all into cylindrical
Structure, riveting cap is provided with top cambered surface, and the lock sleeve is into round table-like.
As a kind of preferred technical scheme of the utility model, the pressure head and riveting cap bottom surface are into 45 degree of angles.
Compared with prior art, the beneficial effects of the utility model are：The Novel rivet, by setting interior retainer, external lock
Circle and lock sleeve complete rivet work, while inside and outside double locking can more keep the fastness of riveting, by by riveting
Nail is put into the rivet mouthful of connector, and lock sleeve is socketed on rivet bar, in riveting work, tailpiece pressure is given by riveting gun
Power, enveloped disconnects from rivet bar while compression, and expansion rod enters the corresponding inside groove of rivet bar due to the impulses of pressure,
The first punch-pin and the second punch-pin agree with into the first notch and the second notch on inside groove simultaneously, interior retainer under the effect of the pressure,
So that plastic deformation occurs for inside groove, interior retainer is insisted, while elastic expansion occurs for rivet bar, forces lock sleeve to occur plasticity shape
Become, outer retainer is locked, now riveting cap receives pressure so that pressure head applies pressure to bearing of trend so that connector is to riveting
Compressed at bar, when exerting a force fully sufficient, pressure head deformation folds into holding groove, keeps the planarization of rivet, enters completely in expansion rod
When entering inside groove, the afterbody of expansion rod carefully rolls over neck and tailpiece disconnects, because the height of tailpiece need not be blocked up, thus material compared with
Few, the waste caused is less.
