The handle part that connects to two end of the base includes a pair of outside-arms, inside-arms, holders and push-arms with a perforation in the middle. The pulling part which is through into the base and the front tube of the body includes an adjustable nut, an adjustable shaft and a rod, and the adjustable nut with a notch outside which is place on the adjustable groove of the base. The notch is used to a shaft of a slot of the base through in, and interior of front end the adjustable nut has a thread. As above described, the adjustable shaft is through into the middle perforation and the adjustable nut of push-arms with a front thread which can be screwed to the thread of the adjustable nut. The rod screws to the adjustable nut and front end of the adjustable nut extend to the front tube. By this, we can get the function of adjustment of riveter operation. And then we can effectively control the pulling force of riveter machine and ensure the process quality of riveter operation.
