[0030] Furthermore, the number of the first tooth-shaped protrusions 101 and the number of the first tooth-shaped grooves 102 are both two, which are distributed at both ends of the first special-shaped steel 1 .

[0031] The interior of the rectangular groove 204 is plugged with a fixing block 3 extending into the interior of the slot 1010. The fixing block 3 is fixedly connected with a circular protrusion 302 at the end away from the first tooth-shaped protrusion 101. The internal thread of the threaded hole 203 is engaged with a bolt 4. The surface of the bolt 4 is provided with a circular cavity 401, and the circular cavity 401 cooperates with the circular protrusion 302.
