Abstract: The disclosure relates to a support stand structure with a quick-release wheel mechanism, which includes a stand, a detachable wheeled seat, and multiple fasteners. The stand includes a base. The base has multiple slots and a rear wall. The detachable wheeled seat includes a board and multiple wheels. The board has a front plate disposed above the base and a rear plate projecting over the rear wall. The front plate has multiple tabs extended downwardly and inserted in each slot. Each tab has a through hole. The wheels are mounted on a bottom of the rear plate. The fasteners are installed on a bottom of the base. Each fastener includes a movable pin. Each movable pin is attachable to and detachable from each through hole. Therefore, the support stand has the advantages of stability and saving space with detachable wheels.

Abstract: A support device having multiple degrees of freedom includes a base unit, a first support unit, a second support unit and a hinge unit. The base unit includes a base body. The first support unit includes a first support structure disposed on the base body. The second support unit includes a second support structure disposed between the first support structure and at least one display. The hinge unit includes a first hinge structure connected between the first support structure and a first end of the second support structure and a second hinge structure connected between a second end of the second support structure and the at least one display. Therefore, the second support structure can be pivotally disposed on the first support structure through the first hinge structure, and the at least one display can be pivotally disposed on the second support structure through the second hinge structure.
