Through the cooperation of the horizontal buckle and the horizontal card slot, the connection between adjacent arc-shaped tubes is ensured to be tight. At the same time, the vertical buckle also cooperates with the vertical card slot on the outer wall of the alumina ceramic layer. On the one hand, the buckle-type reinforcing rib can effectively connect the outer protective sleeve and the alumina ceramic layer tightly and prevent torsion between the two.
