The electronic expansion valve structure comprises a valve seat and a shell, a valve element seat is arranged in the valve seat, a valve element capable of moving in the axial direction of the valve element seat is arranged in the valve element seat, a rotor and a transmission rod which are coaxially arranged are arranged in the shell, and the transmission rod is fixedly connected with the rotor in an axial limiting and circumferential rotating mode. The central axis of the transmission rod and the central axis of the valve element are not collinear, and the transmission rod and the valve element are in transmission connection through a worm rack mechanism. The invention provides a brand-new split type transmission valve core structure to realize transmission and adjustment of the opening degree of a valve port and change of a step angle.
