• a connecting member having two opposite ends and a cam part, wherein the two opposite ends are respectively defined as a first end and a second end, and the connecting member is configured to be driven to rotate around a central axis;
• a flexible bearing having an inner ring and an outer ring, wherein the inner ring is fixed at a periphery of the cam part, and when the connecting member is driven to rotate, the cam part and the flexible bearing jointly form a wave generator;
• a flexspline connected to the outer ring of the flexible bearing by an inner side thereof, wherein the flexspline has a plurality of outer gear-shaped structures formed on a periphery of the flexspline;
• a first frame, part of which is pivotally connected to a periphery of the connecting member;
• a first circular spline being a ring-shaped structure and having a plurality of first inner gear-shaped structures, wherein the first circular spline and the first frame are fixed to each other, and the first inner gear-shaped structures and the outer gear-shaped structures are meshed with each other;
• a second frame, part of which is pivotally connected to the periphery of the connecting member, wherein the second frame is configured to be connected to an outer output member, and when the second frame is driven to rotate, the second frame rotates around the central axis;
• a second circular spline being a ring-shaped structure and having a plurality of second inner gear-shaped structures, wherein the second circular spline and the second frame are fixed to each other, and the second inner gear-shaped structures and the outer gear-shaped structures are meshed with each other;
• and
• an end cap fixedly disposed on an end of the first frame, wherein the end cap and a periphery of the second frame are pivotally connected to each other;
• wherein a quantity of the first inner gear-shaped structures of the first circular spline is equal to a quantity of the outer gear-shaped structures of the flexspline, and a quantity of the second inner gear-shaped structures of the second circular spline is greater than the quantity of the outer gear-shaped structures of the flexspline;
• a driving unit connected to the connecting member;
