Suspension type thread passing mechanism for rotating shuttle rod of embroidery machine

The invention discloses a suspension type thread passing mechanism for a rotating shuttle rod of an embroidery machine, and relates to the technical field of industrial embroidery machines. The suspension type thread passing mechanism for the rotating shuttle rod of the embroidery machine comprises a rotating shuttle supporting unit, wherein a three-tooth rotating shuttle driving unit is fixedly arranged in the rotating shuttle supporting unit. A three-tooth transmission structure is adopted, and the three-tooth transmission structure internally comprises two special-shaped gears which are coaxially arranged, so that the purpose of driving the rotating shuttle to rotate at a high speed can be achieved, a rotating shuttle driving rod can extend to the outer part of a rotating shuttle box, a hollow rod arranged in the rotating shuttle driving rod in a suspended mode is used for leading sewing threads into the rotating shuttle, and the replacement frequency of thread cores is reduced; and a flow dividing oil cha
