[0002] Rivet nuts, also known as pull rivet nuts or pull caps, are used for fastening various metal sheets and pipes in the manufacturing industry. They are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. Developed to address shortcomings such as the fusibility of welding nuts on thin metal sheets and thin tubes, the tendency of base materials to deform during welding, and the tendency of internal threads to slip when tapping. They eliminate the need for tapping internal threads or welding nuts, provide a secure, efficient, and easy-to-use riveted connection.

[0003] During the operation of the specific embodiment, the inventors found the following defects:

[0004] However, after the rivet nut is installed inside the hole of the plate, when the bolt is installed inside the rivet nut, if the rivet nut is not stably fixed to the hole, the bolt will drive the rivet nut to rotate as well during rotation, causing the rivet nut to be unable to connect with the bolt.

[0023] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0026] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example
