Each sealing cover body 5 is fixed at a designated position of the unit by a mounting bolt 5-3, and a retreating slot 5-1 is formed inside each sealing cover body 5 near the rotating shaft 7. The retreating slot 5-1 is formed on the side opposite to the rotating shaft 7 to form a penetrating first push rod hole 5-2;

[0024] Each of the sealing teeth 6 is placed in the corresponding retreating slot 5-1 of the sealing cover body 5, the inner side of which can contact the rotating shaft 7, and the outer side is concave to form a forward slot 6-1, and the forward slot 6-1 is formed with a penetrating second push rod hole 6-2 on the side opposite to the rotating shaft 7;

[0025] The toothed push rod 3 passes through the first push rod hole 5-2 and the second push rod hole 6-2, one end of which is a translation tooth 3-1, and the other end is a T-shaped push rod 3-2, the T-shaped push rod 3-2 can be movably placed in the forward slot 6-1 of the sealing tooth 6 and cannot be pulled out, the translation tooth 3-1 is exposed outside the first push rod hole 5-2 of the sealing cover body 5, the body of the toothed push rod 3 is sleeved with a columnar spring 3-3, the columnar spring 3-3 is located in the backward slot 5-1 of the sealing cover body 5 and abuts between the sealing cover body 5 and the sealing tooth 6;
