By sliding the transverse adjustment rod in the transverse adjustment cylinder, the positioning pressing head moves above the metal material. Then, an external device is used to rotate the hexagonal fastening head. The rotation of the hexagonal fastening head drives the fastening screw rod to rotate. Through the rotation of the fastening screw rod, the fastening nut moves. The movement of the fastening nut drives the hexagonal longitudinal adjustment tube to move. Through the movement of the hexagonal longitudinal adjustment tube, the positioning pressing head moves towards the metal material, so that the positioning pressing head contacts one end of the metal material, and one end of the metal material is fastened on the high-temperature resistant protective sleeve ring.
