Height adjustable holding apparatus

A height adjustable holding apparatus for supporting a display comprising:

• a holding component;
• a moving component being disposed along the holding component, wherein the moving component connects to the display being movable along the holding component;
• an elastic component, wherein the one end of the elastic component is connected to the holding component;
• an active component being disposed on the holding component;
• a gear being disposed on the holding component, wherein the gear rotates together with the active component and driving the active component;
• a driven component being disposed on the holding component, wherein the driven component rotates together with the active component;
• and
• a rolling component being disposed on the holding component, wherein the rolling component rotates together with the driven component;
• a rack disposed on the moving component along the direction of the moving component and engaging with the gear;
• and
• a cable, wherein the one end of the cable is connected to the side of the rolling component and the other end of the cable is connected to the other end of the elastic component, and the rack drives the active component to rotate together with the driven component when the moving component generates a first displacement, the rolling component rolls back the cable and makes the elastic component to generate a second displacement smaller than the first displacement.

An electronic device comprising:

• a display;
• a holding component;
• a moving component being disposed along the holding component, wherein the moving component connects to the display being movable along the holding component;
• an elastic component, wherein one end of the elastic component is connected to the holding component;
• an active component being disposed on the holding component;
• a first rolling component being disposed on the holding component, wherein the first rolling component rotates together with the active component and drives the active component;
• a driven component being disposed on the holding component, wherein the driven component rotates together with the active component;
• a second rolling component being disposed on the holding component, wherein the second rolling component rotates together with the driven component;
• a first cable, wherein one end of the first cable is connected to the moving component and the other end of the first cable is connected to the side of the first rolling component, the first rolling component is able to roll back the first cable;
• and
• a second cable, wherein one end of the second cable is connected to the side of the second rolling component and the other end of the second cable is connected to the other end of the elastic component, and the first cable drives the active component to rotate together with the driven component when the moving component generates a first displacement, the second rolling component rolls back the second cable and makes the elastic component to generate a second displacement smaller than the first displacement.
