The utility model relates to the technical field of pumping well pump inspection, in particular to an anti-eccentric-wear bleeder. The anti-eccentric-wear bleeder is characterized in that the upper end of the oil pipe connector of the bleeder is connected with an oil pipe 88.9mm in diameter, the lower end of the oil pipe connector is connected with an oil pipe 73mm in diameter, a hollow pin and a metal seal ring are mounted on the side wall of the step lower angle of the oil pipe connector, a special-shaped lifting ring is mounted in the oil pipe connector and fixed through fixing screws, a conical circular hole larger than the diameter of the circular section of the front end of the hollow pin is formed in the special-shaped lifting ring, the front end of the hollow pin is inserted into the conical circular hole, and a ledge is designed on the lower portion of the special-shaped lifting ring. The anti-eccentric-wear bleeder has the advantages that seal failure, caused by eccentric wear, of the bleeder can be eliminated effectively, fatigue damage, caused by vibration generated by eccentric wear, to the hollow pin is eliminated thoroughly, the anti-eccentric-wear bleeder is simple in structure and reliable in performance, machining difficulty is lowered, safe downhole application of the bleeder is guaranteed, and the defect of seal failure, caused by eccentric wear, of the existing shearing ring bleeders are overcome.
