A blind rivet or a pop rivet is composed of a rivet core composed of a head, a rivet body and a cutting groove, and an expansion part comprising an expansion cylinder and a flange In order to fasten the blind rivet, a fastening hole is drilled in two or more plate members, a head portion of the blind rivet is inserted into the fastening hole, and then a rivet is pulled by using a separate tool, And the rivets and the rivet body are separated from the cutting grooves, so that the two plates are integrally joined.

In the riveting process using the blind rivet as described above, a separate tool such as a rivet gun for separating the rivet shim from the rivet body is used, but before that, it is necessary to drill a fastening hole in two or more plates.

That is, although the process of fastening the blind rivets to the fastening holes drilled in two or more plates is easier than the manual fastening, there is a problem that the fastening holes for fastening the blind rivets still have to be manually operated.

In this way, drilling and riveting work alternately in the field of riveting, so both riveting and drilling are required for riveting. In addition, in the case of a drill, since an electric drill is usually used, an electrical element such as a wire and a battery required for driving the drill is required, which is troublesome. Repeated use of rivets and drills in this way increases the fatigue of the worker and is not efficient in terms of work time.

Therefore, it is necessary to devise a one-piece rivet gun combined with other air for preventing the above-mentioned troublesome operation.
