Swinging double-well pumping unit

The invention aims to provide a swinging double-well pumping unit, which solves the technical problems of high manufacturing and using costs, high energy consumption and frequent positive and negative rotation in technical background. A crank wheel is used as a core transmission component, a crank arm is fixedly arranged on the crank wheel, a part of the crank arm extends out of the circumferential outer edge of the crank wheel, a permanent magnet synchronous motor is generally selected as a power source, and the crank wheel is coaxial with a main shaft of the permanent magnet synchronous motor; or an asynchronous motor is used as a power source, and the crank wheel is coaxial with a power output shaft of a speed reducer driven by the asynchronous motor; and the pumping unit is also provided with a crank connecting rod, one end of the crank connecting rod is in matched connection with the crank arm through a (crank arm) shaft pin, and the other end of the crank connecting rod is in matched connection with the
