Patent ID: 8867962

Claim:
A driving component comprising: a gear having one fixed end; and a regulating component having a rotational driving force receiver outside the other end projecting from said gear, wherein, said regulating component is provided within said gear by being moved reciprocally and translationally along the longitudinal direction of said gear and a first direction perpendicular to the longitudinal direction relative to said gear; a spring support part and a longitudinal position limit part are provided between said regulating component and said gear; and said rotational driving force receiver is provided inside said regulating component by rotating around its own axis; wherein, said regulating component comprises a motion subassembly and a regulating rod, said regulating rod having a chute, said motion subassembly is provided within said chute by being moved reciprocally and translationally along a second direction perpendicular to the longitudinal direction of said gear relative to said regulating rod, and said second direction intersects with the projection of said first direction on the same radial plane of said gear; and wherein, said motion subassembly comprises said rotational driving force receiver and a regulating slider, wherein said rotational driving force receiver is rotationally connected to said regulating slider around its axis and a rotation limiting pin is provided between said rotational driving force receiver and said regulating slider.
