The invention discloses a handle forming mechanism and belongs to the technical field of metal wire bending and forming machinery. The handle forming mechanism comprises a base, a mold head seat, an action vat, a pair of wire laying devices, and an upper mold frame, a first holding arm and a second holding arm. A stand column set is fixed on the base, and a lower mold frame is fixed on the stand column set. The mold head seat is fixed with one side of the lower mold frame, and handle foot forming grooves are respectively arranged in the upper surface of the mold seat. A mold handle matching cavity is arranged in the middle of the mold head seat. The mold handle matching cavity corresponds to an allowance cavity and is communicated with the allowance cavity. A mold head is composed of a semi-cylinder body and a mold handle, and two sides of the semi-cylinder body are respectively provided with two handle foot forming molds. The action vat is fixed on the base. The pair of wire placing devices are respectively arranged at two sides facing upwards of the lower mold frame. A holding arm frame is fixed at one side of the upper mold frame, and the first holding arm and the second holding arm are respectively connected at two ends of the holding arm frame and connected with two sides of the upper mold frame so as to respectively form a first holding arm arc cavity and a second holding arm arc cavity. Each wire laying device comprises a vertical arm, an adjusting baffle, a material placing board and a pair of tension springs. Operation intensity is reduced, efficiency is improved, quality is ensured, and operation and maintenance are convenient.
