The bottom of the frame is disposed on the foundation, and the top of the frame is supported by the support rod. The top of the support rod is hinge connected to the frame, and the bottom of the support rod is hinge connected to the foundation. The bracket is disposed on the foundation, the transmission shaft is disposed on the bracket, and the crank is disposed on the transmission shaft. The crank rotates synchronously with the transmission shaft, and the belt pulley is disposed on one end of the crank via the pin shaft. One end of the belt bypasses the crown sheave, and is connected to a smooth sucker rod.
