[0012] As the further description of the above technical solutions: the outer wall of the outer rod is provided with a threaded hole, and the outer cavity is oval.

[0013] As the further description of the above technical solutions: the number of the tensioning mechanisms is two groups, and the two groups of tensioning mechanisms are symmetrically arranged at the front and rear ends of the outer wall of the outer rod at equal intervals.
