Specific implementation mode
A preferred embodiment is named, and completely illustrates the utility model in conjunction with attached drawing to become apparent from.
As shown in Figs. 1-2, include for the stud 10 of wind-driven generator (not shown)：Polished rod 100 and connect respectively
It is connected to two screw rods 200 at the both ends of polished rod 100.Polished rod 100 includes：First body of rod 110 and it is connected to first body of rod
Two second bodies of rod 120 at 110 both ends.The diameter of first body of rod 110 is more than the diameter of second body of rod 120, and second body of rod
120 diameter is less than the path of screw rod 200, and one end that two screw rods 200 are not connect with polished rod 100 is equipped with Hexagon hole 210.
Polished rod 100 refers to that the part for being not provided with screw thread, screw rod 200 refer to setting threaded part.
