The specific embodiment:
Be the operation principle of the present invention and the course of work below:
Three rotational freedom muscle joint a as shown in Figure 2, three expansion muscle a1 at interval inflate simultaneously, and remaining three expansion muscle a1 exits simultaneously, and then workbench a5 rotates with respect to base platform a4.Any one or two adjacent expansion muscle a1 inflate simultaneously, and remaining expansion muscle a1 responsively exits, and then workbench a5 is that rotate at the center with respect to base platform a4, with the spherical hinge of universal ball joint a3; Otherwise, keep the chamber pressure of six expansion muscle a1 identical, then the joint is returned to workbench a5 and is parallel to base platform a4 and original state in relative rotation not.
Three rotational freedom spring muscle joint b as shown in Figure 7, its operation principle is identical with aforesaid three rotational freedom muscle joint a, just in its expansion muscle b1 how compression spring b12, need to be used to the ankle joint of damping.
A rotational freedom spring muscle joint c as shown in Figure 9, gas enters the cavity of elastic bellows c8, the elongation of elastic bellows c8 linear expansion, thus the effect that overcomes torsion spring c3 rotates counterclockwise loose-leaf hinge c2, and the joint is stretched; Limiting plate c1 guarantees that loose-leaf hinge c2 can not rotate counterclockwise again when stretching the position; The cavity exhaust of elastic bellows c8 leans on the effect of torsion spring c3 that loose-leaf hinge c2 is clockwise rotated, and makes arthrogryposis.
The crooked muscle joint d of a rotational freedom as shown in Figure 14, gas enters the cavity of elastic bellows d7, owing to be subjected to the restriction of loose-leaf hinge d6, the bending of elastic bellows d7 compliance, the effect that makes loose-leaf hinge d6 overcome torsion spring d5 rotates counterclockwise, and makes the joint constantly crooked; The cavity of elastic bellows d7 is not inflated, and then the joint keeps angle of bend; Otherwise the cavity exhaust of elastic bellows d7 leans on the effect of torsion spring d5 that the joint is stretched.
Three rotational freedom rope yarn traction joint e as shown in Figure 15, minitype cylinder e6 draws any one or two adjacent pull rope e2, remaining pull rope e2 correspondingly loosens, and then upper mounting plate e7 is that rotate at the center with respect to lower platform e5, with the spherical hinge of universal ball joint e4; Otherwise the active force of six minitype cylinder e6 is identical, and then the joint is returned to original state.Three pull rope e2 are at interval drawn by minitype cylinder e6 simultaneously, and remaining pull rope e2 correspondingly loosens simultaneously, and then upper mounting plate e7 rotates with respect to lower platform e5.
Two rotational freedom rope yarn traction joint f as shown in Figure 17, minitype cylinder f6 draws any one or two pull rope f3, remaining pull rope f3 correspondingly loosens, and then roundlet platform f1 is that rotate at the center with respect to big round platform f5, with the spherical hinge of universal ball joint f4; Otherwise minitype cylinder f6 active force is identical, and then the joint is returned to original state.
A rotational freedom rope yarn traction joint g as shown in Figure 18, the piston rod of minitype cylinder g3 is withdrawn in cylinder, and the active force that driving pull rope g1 overcomes torsion spring g6 stretches the joint; The piston rod of minitype cylinder g3 stretches out, and loosens pull rope g1, leans on the active force of torsion spring g6 to make arthrogryposis.
