Compared with prior art, the utility model has the following advantages:
1, whole Distribution of Institutions is symmetrical, is convenient to separate envelope, direct upper lifting pipe post shear pin, it is not necessary to other operations;
2, each string holes size is substantially identical, and central distribution is on same circle, can make mandrel internal diameter maximumization, is convenient to connect the big oil pipe of internal diameter;
3, multiple aperture passes through body, passes through respectively for two electricity pump six roots of sensation cable, and good airproof performance, resistance to pressure is strong, and top pressure can reach 70MPa.
