Abstract: A clamp includes first and second legs pivotally and crosswise attached to one another, with a closing mechanism connected to both legs. The closing mechanism includes an anchor body having a threaded bore engaged with a threaded screw. A distal end of the threaded screw engages a drive body. Two drive-body links each have a first end engaging the drive body and a second end engaging one of the first and second legs at link joints so that when the drive body is urged in a distal direction by the drive screw, the respective first ends and the respective second ends are urged together. The clamp may form part of a computing device stand with a base arm connected to the clamp, a main arm connected to the base arm, and a device-receiving attachment operatively connected to the main arm.
