Fastening structure of jewellery

摘要

A fastening structure of jewelry has a chain, and a locking seat and a locking assembly respectively mounted on two ends of the chain. The locking seat has an insertion recess with two stop protrusions. The locking assembly has a V-shaped resilient locking element and a resilient supporting element. The resilient locking element has a connecting end and a locking end with a pressing protrusion. The resilient supporting element is mounted between the connecting end and the pressing protrusion. The fastening structure has a simplified structure and compact size. Moreover, when the resilient locking element is inserted into the insertion recess of the locking seat, an end edge on the locking end of the resilient locking element securely abuts against the stop protrusions of the locking seat. Accordingly, the jewelry with the fastening structure does not drop off and does not get lost.
