[0032] In the embodiment, the lower connecting rod 3 is provided with a first limiting groove, the upper connecting rod 5 is connected with the lower connecting rod 3 at the position, one end of the upper connecting rod 5 is located in the first limiting groove, the middle rotating shaft 4 penetrates the lower connecting rod 3 and the upper connecting rod 5 to movably connect the two, further, the upper connecting rod 5 is provided with a second limiting groove, and the first limiting groove and the second limiting groove can be folded into a U-shaped limiting groove structure by a plane plate. The upper support 8 comprises a mounting groove plate and a mounting plate, the mounting groove plate comprises a U-shaped mounting groove, and the opening end of the mounting groove faces the top of the upper connecting rod 5, the top of the upper connecting rod 5 is mounted in the mounting groove, and the upper rotating shaft 7 penetrates the mounting groove plate and the top of the upper connecting rod 5 to movably connect the two, the mounting plate is a flat plate structure, and it is connected with the bottom of the mounting groove plate in an integral molding or welding manner, wherein one end of the torsion spring 6 is fixed on the mounting plate, and the other end of the torsion spring 6 is connected with the upper rotating shaft 7. It should be noted that the upper support 8 can be selected as a hollow cuboid structure, and the other end of the torsion spring 6 is connected with the upper connecting rod 5.

[0033] In the embodiment, the end of the upper connecting rod 5 connected with the lower connecting rod 3 is provided with a waist-shaped slot hole 12 through which the middle rotating shaft 4 passes; the waist-shaped slot hole 12 is provided with a lower rotating center 13 and an upper rotating center 14, and the lower rotating center 13 and the upper rotating center 14 are respectively located at the two ends of the waist-shaped slot hole 12, and the first limit position 15 and the second limit position 16 are further provided at the position where the upper connecting rod 5 is connected with the lower connecting rod 3, and it should be noted that the waist-shaped slot hole 12 can be in the shape of a circular arc or a straight line.
