Corrosion resistance can reduce human error, reduce the important advantages such as cost.
（2）The utility model is connected with compression mold cavities by being mounted on the blank holder of rivet body outer surface so that rivet set
It is ratcheting so as to fulfill fastening requirements with screw rod that plastic deformation will occur due to the extruding of press mold chamber, and in rivet ontology appearance
Face utilizes ring-groove-type structure design connecting plate, is designed using unique annular groove, so as to special with high-clamping force and high shearing resistance etc.
Point will generate permanent high fastening force after installation is complete, and it is loose under vibrating conditions that this fundamentally solves General fasteners
The problem of dynamic.
（3）The utility model is by the cruciform recess of rivet cover upper end using extraneous pressure equipment under compression mold cavities
It moves, compression mold cavities, which are pressed down against rivet set, makes it generate plastic deformation, forms screw thread and conjunction fastening is ingeniously sneered with rivet, so as to complete to contact
Forming process improves the fastening performance of rivet interlacement.
