The end of the drive rod (421) away from the docking sleeve body (112) passes through a vertical slot (422) opened in the side wall of the assembly box (111) and is fixed with a rectangular plate (426) and a first rectangular frame (427) that are vertically distributed. The first rectangular frame (427) has a first rectangular slot in the middle. A mounting rod (423) is fixed to the outside of the assembly box (111). The mounting rod (423) is provided with a second rectangular frame (424) that passes through the first rectangular groove, and a second rectangular groove is opened on the second rectangular frame (424). The bolt (425) provided in the second rectangular groove is used to lock the position of the drive rod (421) when the bolt (425) passes through the second rectangular groove and is threadedly connected to the screw hole opened on the rectangular plate (426).

5. The wind turbine wind vane replacement fixture according to claim 3, characterized in that: The screw cap body includes: The outer threaded sleeve (311) is fixed to the bottom of the assembly box (111); An inner threaded sleeve (312) is threadedly connected to an outer threaded sleeve (311). And a sealing ring (313) fixed to the bottom of the inner threaded sleeve (312).

6. The wind turbine wind vane replacement fixture according to claim 5, characterized in that: The telescopic extension head includes: A conical head sleeve (411) is fixed at the bottom of the outer threaded sleeve (311), and a through groove (412) is provided on the conical head sleeve (411) in an annular shape. A fixing post (414) is longitudinally fixed in the middle of the fixing plate (413) and passes through the outer threaded sleeve (311) and the conical bottom sleeve (411) in sequence. An assembly plate (415) is fixed at one end of the fixing post (414) away from the fixing plate (413). The assembly plate (415) is hinged with extension strips (417) one by one through the hinges (416) arranged in a ring on it. And a transmission component disposed between two transmission rods (418) and several extension bars (417) for driving several extension bars (417) to perform outward and inward movements.

7. The wind turbine wind vane replacement fixture according to claim 6, characterized in that: The transmission component includes: A transmission sleeve (419) is fixed to one end of the two transmission rods (418) away from the docking sleeve body (112) and sleeved outside the fixed post (414). And a plurality of hinge rods (420) are provided on the outer wall of the end of the transmission sleeve (419) away from the transmission rod (418), wherein the end of each hinge rod (420) away from the transmission sleeve (419) passes through the corresponding through slot (412) and is hinged to the end of its corresponding extension bar (417) away from the hinge member (416).
