Abstract: A cable management device includes a first main body and a second main body. The second main body is connected with the first main body. The second main body is elastically deformable, and selectively in an unwrapped state or a wrapped state. When an elongated strip of the second main body is in the unwrapped state, two ends of the elongated strip are far away from each other. Consequently, a connecting cable can be easily wound around the first main body. In response to an external force, the second main body is elastically deformed to the wrapped state. In the wrapped state, the two ends of the second main body are close to each other, and the connecting cable on the first main body is confined. Consequently, the cable management device can protect the connecting cable, and the cable management device has a compact and small size.

Abstract: A trimming apparatus for variously trimming a sheet material is disclosed. The trimming apparatus includes a base for placing the sheet material thereon, a rail mounted on the base, a first trimming element for trimming the sheet material in a first manner, a second trimming element for trimming the sheet material in a second manner, a carriage movably engaging with the rail, having a first and a second portions coupled to the first and second trimming elements, respectively, and having a third portion for being exerted thereon a driving force to move along the rail, thereby carrying a selected one of the first and second trimming elements to cross over the sheet material.

Abstract: A cutting apparatus providing a flat material with a curved edge is disclosed. The cutting apparatus includes a main body, a center member and an arm. The center member is mounted to the main body. The arm engages with the center member and has a cutting part thereon. The cutting part cuts the flat material to have the curved edge by rotating the arm about the center member.
