Rotating mechanism for stamping ring patterns and a stamp tool thereof

A rotating mechanism for annular pattern stamping comprising:

• a base (4);
• a rotating unit (5) rotatably disposed on the base (4), the rotating unit (5) having a first clamping plane (50) at a top thereof;
• an operating unit (6) detachably disposed on the rotating unit (5), the operating unit (6) having a second clamping plane (60) at a bottom thereof;
• wherein,
• a clamping space is defined between the rotating unit (5) and the operating unit (6) for clamping a stamping carrier;
• the first clamping plane (50) is opposed to the second clamping plane (60), and the clamping space is defined between the first clamping plane (50) and the second clamping plane (60),
• the operating unit (6) is capable of rotating together with the rotating unit (5) and the stamping carrier in the clamping space relative to the base (4);
• a plurality of first magnetic pieces (51) is embedded in the first clamping plane (50) of the rotating unit (5), and a plurality of second magnetic pieces (61) is embedded in the second clamping plane (60) of the operating unit (6), and the operating unit (6) is detachably attached to the rotating unit (5) by the magnetic attraction between the plurality of first magnetic pieces (51) and the plurality of second magnetic pieces (61).
