Patent ID: 11896895

Abstract:
A rotating assembly comprises a rotary shaft, an accommodating body and a position-limiting switch. An outer wall of the rotary shaft includes a first tenon and a second tenon. The accommodating body includes a matching hole for the first tenon to insert and rotate therein. An inner wall of the matching hole includes a convex rib. By rotating the rotary shaft, a side wall of the first tenon and a side wall of the convex rib butt against or separate from each other, so that in an axial direction of the rotary shaft, the rotary shaft is fixed or movable relative to the accommodating body. When the side wall of the first tenon and the side wall of the convex rib butt against each other, the position-limiting switch and the second tenon are clamped together to prevent the rotary shaft from rotating relative to the accommodating body.
