Further, the method can be used for preparing a novel materialAnd the positioning part comprises connecting rods hinged on two sides of the connecting plate, through holes are formed in the movable ends of the connecting rods, and a plurality of ejector rods matched with the through holes are arranged on the upper part of the first sleeve.

Through the arrangement, the through hole on the connecting rod is sleeved on the ejector rod, so that the first sleeve and the second sleeve can be limited.

Further, the method can be used for preparing a novel materialAnd the lower ends of the two second sleeves are connected with a horizontal supporting plate, and bolt holes are formed in the supporting plate along the circumferential direction.

Through the arrangement, the bolt penetrates through the bolt hole, so that the second sleeve can be fixed, and displacement is prevented.

Further, the method can be used for preparing a novel materialAnd both ends of the connecting plate are provided with concave parts matched with the end parts of the first support plate and the second support plate.

Through the arrangement, the end parts of the first support plate and the second support plate are attached to the concave part.
