Fig. 1, Fig. 2 and Fig. 3 depict that the torsion balance device 60 includes a reactor 61 and a responder 62 combined with each other; the reactor 61 and the responder 62 are respectively provided with wings a, b, which normally clamp the first The first and second rotating shafts 10, 20 drive areas 14, 24; and, when the first and second rotating shafts 10, 20 rotate, the wings a and b are forced to expand elastically, and the reactor 61 and the responder 62 move along the first and second rotating shafts. The axial directions of the rotating shafts 10 and 20 generate relative displacement motion.

Specifically, the reactor 61 and the responder 62 respectively have a central area c and at least one convex portion d and concave portion e formed on the central area c; and the convex portion d and the concave portion e are arranged adjacently. In a preferable consideration, both sides of the convex portion d are inclined toward the direction of the concave portion e, forming a slope structure.

Therefore, the convex part d of the reactor 61 is relatively displaced from the position of the concave part e of the responder 62 to the position of the convex part d of the responder 62 along the slope structure, so that the reactor 61 and the responder 62 resist the torsion or pressure of the torsion module 50, Relative displacement motion is produced along this axis; for example, the situation depicted in FIG. 6 .

It can be understood that when the first and second rotating shafts 10, 20 continue to rotate and open, so that the planar parts 14a, 24a enter the reactor 61 and the wing parts a, b of the responder 62, the convex part d (and the responder) of the reactor 61 The convex part d of the responder 62) is relatively displaced to the position of the concave part e of the responder 62 (and the reactor 61), and the torque module 50 also forces the reactor 61 and the responder 62 to return to their original positions along the axis; and, the wings a, b also return to the position in Fig. 4 from the opened state.
