Description

Bracelet chain pin manufacturing device Technical Field The invention relates to the technical field of jewelry processing production, in particular to a bracelet chain pin manufacturing device. Background In the wearing jewelry, bracelets are often used, and there are many forms of bracelets, such as watchband bracelets, in which a plurality of movable members are movably connected in sequence into a strip-shaped wearing bracelet by a plurality of pins. The bracelet chain pin has a form that two ends of the chain pin are burned into the ball heads, the movable piece is clamped in the ball heads at the two ends of the chain pin, the round surface of the ball heads does not hurt hands, the ball heads can also be used as decoration, and the bracelet made of the ball head type chain pin is loved by people more and more. The assembly of the chain pin is to insert the chain pin with one end provided with the ball head into the connecting piece, and then fire the other end to form the chain pin with the ball heads at both ends.
