[0023] Refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 It can be seen that anti-warping edge mechanisms 5 are provided on both sides of the circular wellhead 2. The anti-warping edge mechanism 5 includes a cavity 501, a threaded rod 502, a runner 503, a threaded block 504, a first triangular block 505, a second triangular block 506, a locking rod 507, a connecting rod 508, a spring 509 and a locking groove 510. Cavities 501 are opened inside both sides of the circular wellhead 2. A threaded rod 502 extending to the outside of the cavity 501 is connected inside the cavity 501 through a bearing. A runner 503 is provided at one end of the threaded rod 502. A threaded block 504 is threadedly connected to the surface of the threaded rod 502. A first triangular block 505 is welded to one side of the threaded block 504. A second triangular block 506 is provided on one side of the cavity 501 close to the first triangular block 505.
