Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
As shown in Figure 1, the filling steerable tool of the utility model, including sequentially connected top connection 1 from left to right, filling
Body 3 and transition joint 6, the obturation 3 are connect by left end external screw thread with top connection 1, and the obturation 3 passes through spiral shell in left end
Line is connected with center head 2, and the obturation 3 is connect by right end external screw thread with transition joint 6, and the obturation 3 passes through right end
Internal screw thread is connected with plug 5, is fixedly connected with set 4 with holes by holding screw inside the obturation 3, and set with holes 4 is located at
Between center head 1 and plug 5.
As shown in Fig. 2, the 3 interlude outer diameter of obturation is less than the outer diameter of its left and right ends part, in the obturation 3
Between circumferentially symmetrically open up outside section there are four rectangle side opening 302,3 side wall of obturation is circumferentially opened up is there are four section
