When the receiving seat is pressed to displace downwardly, the disk will adhere to the label.

Abstract: A clamping device for mobile phones includes a fork-shaped link pivotally connected to a clamp seat at either end. Each clamp seat has a lateral side provided with slanting rack teeth. An elastic securing seat is disposed adjacent to the rack teeth and has stop elements for projecting into the rack teeth to force the clamp seats to displace only inwardly to be positioned in place. The securing seat further has slanting notches at its ends. A press rod provided with corresponding slanting notches is passed through the notches of the securing seat. By pressing the press rod, the securing seat is urged to displace rearwardly, bring the stop elements to disengage from the rack teeth. Due to the action of compression springs, the clamp seats are caused to instantly extend to clamp mobile phones of various sizes and types.
