The utility model discloses a water injection well resistance-meeting-resisting concentric throwing-getting switch. The problem that after water injection well construction, in the process of water mouth throwing and getting, well bottom crude oil enters an oil pipe and causes throwing-getting resistance meeting is solved. The water injection well resistance-meeting-resisting concentric throwing-getting switch comprises a tool body and a blocking device. A ball, a ball base and a working cylinder are arranged in the tool body. The blocking device comprises a getting head, a sealing cylinder and a cam connecting rod mechanism. The blocking device is arranged in the working cylinder. An O-shaped sealing ring and a cam are arranged between the blocking device and the working cylinder, sealing performance and stability are guaranteed, a channel of the oil pipe and an oil sleeve annular space is blocked, crude oil in the annular space cannot enter the oil pipe, smoothness of the oil pipe is guaranteed, and throwing getting testing construction can be carried out smoothly. After throwing getting testing, the blocking device is gotten from the working cylinder, an oil flow channel is opened, the concentric throwing-getting switch is changed into a single-way ball base, normal water injection can be guaranteed, and well washing cannot be affected.
