[0022] The left side wall of the insert sealing cylinder 3 is threaded with a limiting bolt 7 extending to the right side of the fixing plate 5. The insert sealing cylinder 3 and the fixing plate 5 have several threaded holes arranged in a ring at equal intervals, which are adapted to the limiting bolts 7. Each limiting bolt 7 has two limiting nuts 8 threadedly connected to its external surface, symmetrically distributed on the left and right sides. The sleeve 2 is externally fitted with a protective component 9 that fits tightly against the outside of the water-cooled wall 4. Both the insert sealing cylinder 3 and the fixing plate 5 are located inside the protective component 9. The protective component 9 includes an arc-shaped protective frame 91. There are two arc-shaped protective frames 91 that fit tightly against the outside of the water-cooled wall 4. The two arc-shaped protective frames 91 are symmetrically distributed vertically. The opposite sides of the two arc-shaped protective frames 91 fit together. The front and rear side walls of the upper arc-shaped protective frame 91 and the front and rear side walls of the lower arc-shaped protective frame 91 are fixedly connected to positioning blocks 92.
