Anti-collision device for oil well pump of oil well

The utility model relates to the technical field of oil production engineering, in particular to an anti-collision device for an oil well pump of an oil well, which comprises a fixed blocking seat and a movable blocking seat, a plurality of fixed anti-impact stop blocks are arranged in the circumferential direction of the inner diameter of the middle section of the fixed stop seat; a plurality of moving anti-impact blocks are arranged in the circumferential direction of the outer diameter of the middle section of the moving blocking seat; the inner diameter of the fixed anti-impact stop block is smaller than the outer diameter of the movable anti-impact block. According to the anti-impact oil well pump, the inner diameter of the fixed anti-impact stop block in the fixed stop seat is smaller than the outer diameter of the movable anti-impact block in the movable stop seat, so that other parts of the oil well pump are prevented from being impacted to the greatest extent when an accident occurs, and the service
