Patent ID: 7336479

Claim:
An adjusting assembly comprising: a monitor; a base; a first pivot assembly comprising a pair of supporting boards attached to the monitor, a pivoting board pivotally mounted between the supporting boards via a first pivot, and a pair of friction gaskets mounted between the supporting boards and the pivoting board, the friction gaskets rub by the supporting board and the pivoting board, wherein when the monitor rotates relative to the pivoting board, the friction gaskets rub against the supporting boards and the pivoting board and generate a friction moment, the monitor generates a first gravity moment opposite to the friction moment; a second pivot assembly having a pair of supporting seats attached to the base, and a second pivot pivotally attached to the supporting seats, a torque-limiting spring placed around the second pivot between the supporting seats with one clasp end engaging with one of the supporting seats; and a connecting assembly mounted between the first pivot assembly and the second pivot assembly, the other clasp end of the torque-limiting spring engaging with the connecting assembly, wherein the torque-limiting spring generates a torque moment under a rotation action between the connecting assembly and the second pivot assembly, the monitor and the connecting assembly generate a second gravity moment opposite to the torque moment; wherein the monitor stays at any obliquity under a balance of the friction moment and the first gravity moment, and stays at any height under a balance of the torque moment and the second gravity moment.
