The invention discloses a sliding sleeve structure for the convenience of controlling pipeline circulation. The sliding sleeve structure comprises a pipe body, a sliding sleeve, an outer thread, an inner thread, a rotary shaft, a slide block, a chute, a pressure block, a fixed plate, a seal ring, a fixed bar, a rotating rod, a supporting rod, a connecting rod, a fixed block and a spring. The sliding sleeve structure is simple in structure and convenient to operate. The seal ring moves as the sliding sleeve moves, so that liquid circulation in a pipeline is controlled favorably, and therefore,the operating convenience is improved, the operating difficulty is reduced and the work efficiency is improved. According to the sliding sleeve structure, the sliding sleeve is fixed favorably as therotary shaft rotates, so that the problem that the sliding sleeve which is used cannot be fixed is solved. By fixing the sliding sleeve, liquid circulation in the pipeline is avoided, so that the pipeline liquid is controlled favorably and the workload of an operator is reduced favorably.
