Description

Technical Field

[0001] The utility model relates to the technical field of staplers, and more particularly to a stapler nail track and cantilever rivet riveting device. Background Art

[0002] A stapler is a tool used to bind many pages of paper together. It is not only common in offices, but also in many homes. The history of staplers can be traced back to their development for the printing industry, but over time, it has evolved into an indispensable gadget in offices and daily life. Among them, the long-arm stapler is a special stapling device designed with a longer arm, which allows operators to handle larger or thicker documents more conveniently. This type of stapler is usually used to bind A3-sized paper or when a larger binding format is required. The long-arm stapler is designed to provide a larger working range, making the binding process more convenient, especially suitable for occasions where larger documents need to be bound. In the production process of the long-arm stapler, it is necessary to rivet the nail channel and the cantilever. Traditional riveting requires manual labor to hammer the rivets, which is not very convenient. For this reason, we propose a riveting device for the stapler nail channel and cantilever.
