The utility model relates to a many bunches of full latus rectum staged fracturing sliding sleeves of unlimited level of counter. The mode that the sliding sleeve was opened to the fracturing ball is thrown in the adoption, the institute bowling number the same with the fracturing hop count, the size of all balls is unanimous. Go up the jack catch and all can follow with the claw head of jack catch down and radially gather together with shutoff fracturing ball, also can resume initial condition with release fracturing ball under the effect of self elastic force. Fluted on top connection and the outer sliding sleeve inner wall, the tally function can be realized with the recess cooperation to interior sliding sleeve. After all interval fracturings are accomplished, the well head pressure release, under the spring action, the ball seat that can restore to the throne restores to the throne, and the fracturing ball returns to be arranged or falls the shaft bottom, and full latus rectum can be realized to whole tubular column. In the one -level, a plurality of top connections, interior sliding sleeve, switch and outer sliding sleeve connect to establish ties through many bunches can realize many bunches of fracturings. Carrying on under the condition of operation not less than income oil pipe or continuous oil pipe, the utility model discloses can satisfy many bunches, unlimited grade and full latus rectum fracturing requirement simultaneously.
