A fastening pin 304 is arranged between the adjusting plate 301 and the inner wall of the mounting plate 101. The rotation of the adjusting plate 301 can adjust the distance between the four support plates 303 through the traction action of the traction plate 302, so that the four support plates 303 can support the inner walls of blast furnace tuyere of different sizes, and the fastening pin 304 can fix the adjusted adjusting plate 301.

[0034] In order to keep the pressure plate 106 stable during the movement, Figure 2-4As shown, a movable groove 103 is opened on the inner wall of the mounting plate 101, and the bottom of the inner wall of the movable groove 103 is fixedly connected to the bottom of the traction spring 104. A slider 105 is fixedly installed on the outer wall of the pressure plate 106 close to the mounting plate 101. The bottom of the slider 105 is fixedly connected to the top of the traction spring 104, and the outer wall of the slider 105 is movably connected to the inner wall of the movable groove 103. The movable groove 103 can limit the movement of the slider 105, so that the pressure plate 106 remains stable during the movement.
