Abstract
A flat display holder arm includes a tension spring with one end hooked to a first axial pin crossing both side arms and the other end connected to a steel cord and going around an axial pin at the base before being hooked to an axial pin crossing a mobile seat; length, i.e., strength of the tension spring being adjustable by the steel cord to set up the supporting force of the arm by the tension spring to reduce the weight of the holder, thus the production costs of parts.
Claims1
