In general, rivet refers to integrally fastening at least two or more plates (connectors) such as plates, sections, or mechanical and mechanical devices, and various workpieces. Next, the locking jaw, or head, is formed by a hammer or a mechanical device, and the head is formed and fixed. Since these operations are performed by hand, the connection process is complicated and the defect rate depends largely on the skill of the operator.

Therefore, in recent years, various types of rivets have been developed to enable simple and efficient riveting operations, and blind rivets are used for this purpose.

The blind rivet is composed of a rivet shim consisting of a head, a rivet body and a cutting groove, and an expansion cylindrical body coupled to the rivet shim and consisting of an expansion cylinder and a flange, for fastening the blind rivet to two or more plates. Drill a hole, insert the head of the blind rivet into the fastening hole, and then use a separate tool to pull the rivet seam so that the end of the expansion cylinder is extended, and the rivet seam and the rivet body start from the cutting groove. The two plates are integrally combined while being separated.

As described above, in the process of riveting two or more plates using blind rivets, a separate tool for separating the rivet core from the rivet body should be used. Of course, it is natural that an operator must drill a fastening hole in two or more plates before that.

That is, two or more plates can be easily riveted by using a blind rivet, but there is a problem in that a work of drilling a fastening hole for fastening the blind rivet and removing a rivet core from the blind rivet must be performed separately.
