An aspect of the present invention provides a jewelry buckle 100, wherein the jewelry buckle 100 is used to connect the head end and the tail end of a chain jewelry, and of course, the jewelry buckle 100 can also be used for other jewelry pieces requiring the head end and the tail end to be connected, such as a bracelet.

The jewellery buckle 100 comprises a connecting element 10, a support element 20, a mobile element 30 and an elastic return element 40. The connecting piece 10 is used for connecting the tail end of the chain-shaped jewelry; the supporting member 20 comprises a first end and a second end, and the first end of the supporting member 20 is connected with the connecting member 10; the movable piece 30 comprises a pressing end 31 and a buckling end 32, the middle part of the movable piece 30 is rotatably connected with the support piece 20, and the buckling end 32 of the movable piece 30 is in buckling fit with the second end of the support piece 20 and is used for connecting the head end of the chain jewelry; the two ends of the elastic restoring element 40 respectively abut against the pressing end 31 of the movable element 30 and the first end of the supporting element 20, and exert a force that the fastening end 32 and the second end are fastened oppositely on the movable element 30 and the supporting element 20.

In the jewelry buckle 100 in this embodiment, the first end of the supporting member 20 is connected to the tail end of the chain jewelry through the connecting member 10, the supporting member 20 is rotatably connected to the middle position of the moving member 30, and the second end of the supporting member 20 is in buckling fit with the moving member 30 to be used for buckling fit with the head end of the chain jewelry, that is, the head end of the chain jewelry can be buckled and connected to the second end of the supporting member 20 by the buckling end 32 of the moving member 30, so that the head end and the tail end of the chain jewelry are connected.

Since the middle portion of the movable member 30 is connected to the supporting member 20, the pressing end 31 and the fastening end 32 are located at two ends of the movable member 30, and the elastic restoring member 40 is located between the pressing end 31 of the movable member 30 and the first end of the supporting member 20, when the pressing end 31 presses the elastic restoring member 40, the fastening state of the fastening end 32 and the second end is changed to the non-fastening state, and when the pressing end 31 is released, the fastening end 32 and the second end are automatically changed to the fastening state from the non-fastening state.

For traditional adoption lobster clasp or circular knot carry out the mode of block, this kind of mode, the area of contact who presses down end 31 is big, presses down conveniently, just can realize the state that opens and shuts of lock end 32 and second end through pressing down and loosening the end 31 of pressing down of moving part 30, and convenient operation is swift, and the user of being convenient for carries out wearing and taking off of ornament to the head end and the end-to-end connection lock operation of chain form ornament.

Specifically, the supporting member 20 is a C-shaped structure, the supporting member 20 includes a connecting portion 21, and an upper arm 22 and a lower arm 23 fixed to the same side of the connecting portion 21, the lower arm is provided with a movable groove 231 along the upper arm 22, the movable groove 231 is adapted to the movable element 30, the fastening end 32 of the movable element 30 is located between the upper arm 22 and the lower arm 23, and the fastening end 32 of the movable element 30 is fastened and matched with the upper arm 22; the connecting member 10 is connected to the other side of the connecting portion 21 of the lower arm 23 facing away from the upper arm 22. Wherein, the connecting portion 21 is a first end of the supporting member 20, the upper arm 22 and the lower arm 23 are second ends of the supporting member 20, the upper arm 22 and the lower arm 23 are disposed opposite to each other and form an opening of a C-shaped structure, and the opening is communicated with the movable slot 231.
