As the requirements for the use of electrical appliances in various industries continue to increase, the testing specifications for the performance of various components in electrical appliances are also constantly improving. Riveted contact elements are used in various relays, contactors, small switches, thermostats, etc. in low-voltage electrical appliances. The structure of the riveted contact element generally includes a contact base and a rivet riveted to the contact base. The rivet includes a rivet head and a rivet top, the structure of which is shown in FIG. 1 .

In the process of mechanical assembly, we often use pins to connect two parts, and the positioning pins are usually sunk into the pin installation holes on the mechanical parts. During the assembly process or after the assembly is completed, we often need to pull out the pins to assemble, revise or repair the parts. The existing method of pulling out the positioning pins is generally to use tools such as pliers, hand hammers, and blades to pull out the positioning pins, but This method is easy to damage the pin holes and pins, which will directly lead to the scrapping of the original parts. The positioning pin can be pulled out by pulling the pull rod, but in order to ensure the assembly accuracy between the parts, the matching between the positioning pin and the pin hole on the part is tight and the number of pins is large, so this method is inconvenient to operate. And time consuming.

In chemical production equipment, the cylinder body and the head cover need to be connected and sealed. The traditional sealing structure is to connect the two with a screw, add a non-metallic gasket in the middle and fix it with a nut. However, such a sealing structure only controls the tightening torque, and has the technical defect that the sealing ring will be twisted or even broken during repeated loading and unloading of the cylinder head cover, resulting in poor sealing performance.

A rivet is a nail-shaped object used to connect two parts with a through hole and a cap at one end. It is mainly used in riveting to connect the riveted parts by its own deformation or interference.
