Description

Technical Field

[0001] The utility model relates to the technical field of decoration, in particular to a self-drilling riveting tool. Background Art

[0002] During the decoration process, rivets are used for fixing in applications such as the production of light steel frame partitions, aluminum alloy doors and windows, and outdoor curtain wall installation. Rivets are nail-shaped objects used to connect two parts (or components) with through holes and a cap at one end. They use their own deformation or interference to connect the riveted parts. During installation, a rivet tool is used to pull the rivet rod to cause it to deform. Existing rivet tools generally do not have a drilling function. During installation, an electric drill is used to drill holes first, and then the rivets are inserted for riveting. The installation process requires both a handheld electric drill and a manual rivet gun. The tools need to be switched, which is cumbersome and inconvenient to use. Utility Model Content
