When the rivet body is in work, an operator needs to pull the rivet core by means of the hand riveter so as to drive the rivet body to deform and compress a workpiece between the rivet body head and the deformed rivet body. At present, with the trend of weight reduction of automobiles, rivets themselves, which are fasteners, are also gradually reduced in weight. This makes the rivet itself lighter in weight and somewhat less strong. When the original riveter is adopted to rivet the rivet, the end part of the rivet body is easy to deform under the compression of the rivet core, so that the deformation degree of the middle part of the rivet body is reduced, and the riveting tightness is further reduced. Meanwhile, the original rivet must be provided with a special hand riveter for riveting, which limits the use of the rivet in some temporary occasions. Moreover, the rivet body and the rivet core of the original rivet are split, and an operator needs to load the independent rivet core into the rivet body before riveting and then can perform riveting operation, so that not only is the riveting efficiency reduced, but also the situations that the rivet body and the rivet core are not matched or cannot be found for a while exist. In addition, in order to improve the strength of the rivet, the mandrel needs to be left in the body tube after the rivet is fastened, so as to improve the strength of the rivet.
