A control device for unifiedly positioning two symmetric and parallel telescoping rods is disclosed. The control mechanism includes a first controller mounted on a first telescoping rod and a second controller mounted on a second telescoping rod. Each controller controls a pin to position one of the telescoping rods. A linking rod is disposed between the two controllers for unified motion. A torque element is disposed in the first controller. When the first controller is triggered by a cord, the pins will be separately inserted in the telescoping rods for locking. When releasing the cord, the pins will run back to the initial position by the force from the torque element so that the telescoping rods are released for providing a length adjustment.
