Abstract: The present disclosure provides a height and angle-adjustable foldable computer bracket, including a bottom plate, a support plate, and expansion and retraction brackets connected between the bottom plate and the support plate. First connecting lugs are respectively arranged at the top of the bottom plate and the bottom of the support plate. Second connecting lugs are arranged at two ends of the expansion and retraction brackets. Shaft holes are formed in the first connecting lugs and the second connecting lugs. A rotating shaft structure is mounted between each first connecting lug and the corresponding second connecting lug. Engaging teeth are formed in the shaft holes. The rotating shaft structure includes: a rotating shaft with the engaging teeth, a limiting shaft with the engaging teeth, and a returning piece.
