Technical Field

[0001] The utility model relates to the technical field of riveting tools, in particular to a riveting tool for metal sheet metal. Background Technique

[0002] Sheet metal is a metal processing technology that manufactures parts and structures that meet requirements through operations such as shearing, bending, stamping, and welding of metal plates. It involves multiple aspects such as material selection, process flow, equipment use, and application fields. When splicing metal plates is required, riveting is usually used for fixation. Existing riveting tools for metal sheet metal can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] When the widely used riveting tool for metal sheet metal on the market is in use, the metal plate needs to be fixed under the riveting head through a fixing piece for processing. However, in the actual use process, due to the inconvenience of adjusting the existing fixing piece, a large amount of time is required for adjustment when fixing metal plates of different sizes, and the fixing effect is not good.

[0004] Therefore, we propose a riveting tool for metal sheet metal. Content of the Utility Model
