[0003] Riveting can be adapted to the connection between various metal and non-metal materials with complex structures. Riveting is an indispensable tool for body repair operations. As a method for connecting metal structure parts, riveting technology is applicable to rivet connection, part flanging, permanent connection, etc., and is widely used in industries such as hardware tools, aircraft manufacturing and maintenance, precision machinery, and automobile manufacturing. A riveting gun is a kind of riveting tool in riveting. Currently, there are many types of riveting guns in various forms at home and abroad. According to the riveting principle, there are stamping riveting guns, radial riveting guns, orbital riveting guns, and hydraulic riveting guns, etc.

[0004] The patent with the application number 202320550212.1 discloses a riveting gun that can avoid jamming, including a main body mechanism, a grasping mechanism, and a protection mechanism. A grasping mechanism is arranged at one end of the main body mechanism, and a protection mechanism is arranged inside the main body mechanism. The grasping mechanism can stretch different models of rivets by replacing rivet nozzles of different sizes. Then, the protection mechanism is formed by a folding sleeve made of flexible waterproof fabric being attached to the wear-resistant layer on the outside, and two groups of first fixing rings and second fixing rings symmetrically distributed are threadedly connected. At the same time, the two ends of the folding sleeve are clamped and connected by the first fixing ring and the second fixing ring. The folding sleeve is made of flexible waterproof fabric, and the outside of the folding sleeve is attached to the wear-resistant layer. The first fixing ring and the second fixing ring are symmetrically distributed, and a total of two groups of the first fixing ring and the second fixing ring are provided. The connecting end is integrally connected with the second fixing ring, and the connecting end and the internal thread are threadedly connected.
