The invention discloses a variable airfoil parallel mechanism. The variable airfoil parallel mechanism mainly comprises a root mechanism, a middle mechanism and a pointed mechanism, wherein a main body is connected with one side of a base of the root mechanism through a rotating pair A, the other side of a hinge A of the root mechanism is connected with one end of a main rod C of the middle mechanism through a rotating pair F rotating around an X axis, and the other side of a hinge C of the middle mechanism is hinged to one end of a main rod E of the pointed mechanism through a rotating pair J rotating around the X axis. According to the variable airfoil parallel mechanism disclosed by the invention, the folding characteristic and the telescopic characteristic of an airfoil are realized, requirements for a space and a structure are met under different conditions, and the occupied space of the variable airfoil parallel mechanism is small and one third of that of an aircraft of which the size is the same as that of the variable airfoil parallel mechanism when the variable airfoil parallel mechanism is not used; the rigidity of the whole mechanism is guaranteed, besides a great overturning and changing angle is obtained, a first joint is the best section point of the whole airfoil mechanism in a structural geometric size, a second joint is the best section point between the middle mechanism and the pointed mechanism, so that the rigidity of the whole airfoil is guaranteed, besides the deformation of the mechanism is realized, changeable requirements of the whole mechanism are met, and besides different motion control is separated.
