Limiting three-linkage mechanism for jewelry and jewelry with same

The utility model provides a limiting three-linkage mechanism for jewelry and the jewelry with the limiting three-linkage mechanism. The limiting three-linkage mechanism comprises a limiting block, a driving rod and a plurality of driven rods, a containing cavity is formed in the limiting block. The first end of the driving rod and the first ends of the driven rods are arranged in the accommodating cavity; the first end of the driving rod is movably connected with the first ends of the driven rods; the second end of the driving rod and the second ends of the plurality of driven rods extend out of the limiting block; when the second end of the driving rod swings forwards relative to the longitudinal axis of the limiting block, the second ends of the driven rods can be driven to swing forwards relative to the transverse axis of the limiting block; and/or when the second end of the driving rod swings backwards relative to the longitudinal axis of the limiting block, the second ends of the driven rods can be driv
