Further, the adapter sleeve is provided with the fixing pin for preventing that adapter sleeve from rotating.
Further, the upper port of the upper pipe commutation pipe sleeve is enlarging, and internal thread is provided with enlarging.
Further, the down tube fixes the lower port of pipe sleeve provided with external screw thread.
The beneficial effects of the present invention are：
（1）In the case that achievable tool lower portion completion tubular column is motionless, upper tool part completion tubular column can adjust direction；
（2）When Oil/gas Well downhole tool is double Y-shaped connector-electric submersible pump tubing strings, lower Y-shaped connector-electric submersible pump is motionless, and adjustable upper Y connects
Head-electric submersible pump is to proper orientation, it is to avoid electric pump damages risk, and improves the security and completion efficiency of operation；
（3）When Oil/gas Well downhole tool is airtight button completion tubular column, directly boll-weevil hanger regulation can be wanted to oil pipe four-way
The direction asked, without rotating down-hole string with regard to tubing hanger direction can be adjusted；
（4）When Oil/gas Well downhole tool is tripping in screen casing+central tube, during sand control top packer connection screen casing, without rotating
Screen casing and central tube in well, without sand control top packer is rotated, with regard to sand control top packer, screen casing, central tube can be completed
Connection.
