The first support section 41 is slidably connected to the inner wall of the sleeve 43. The first support section 41 can move along the extension direction of the sleeve 43 (the extension direction of the second support section 42) to adjust the length of the first support member 30 and the second support member 40. When the length is shortened, the first support section 41 can be retracted into the sleeve 43. It should be noted that the sleeve 43 is provided with a fixing member to limit the position of the first support section 41. For example, a first fixing hole is provided on the side wall of the sleeve 43, and a second fixing hole is provided on the first support section 41. When the second support section 42 moves to the target position, the first fixing hole and the second fixing hole are aligned. The fixing member penetrates the first fixing hole and the second fixing hole in sequence, thereby limiting the position of the first support section 41. In another embodiment, the first supporting section 41 is also a telescopic structure, and the top of the first supporting section 41 is fixed in the sleeve 43 .

[0045] In order to effectively adjust the direction of the slag inlet 13 of the slag collecting box 10, the embodiment of the utility model drives the slag collecting box 10 to rotate through a rotating assembly.
