ABSTRACT:
A mechanism for adjusting an elevation angle of an LCD includes a base, a U-shaped locking arm, a pawl, a release button, an LCD, two rotation shafts and return springs. The base is disposed with a lower casing and a slot. The U-shaped locking arm is defined with an L-shaped hole. The pawl extends through the L-shaped hole and the slot. The release button connects to the U-shaped locking arm. The LCD is disposed with an upper casing. Teeth are respectively disposed at two ratchet arcs of the upper casing and abut against the pawl. The rotation shafts are pivotally disposed at the U-shaped locking arm, the upper casing and the lower casing. The upper casing and the angular relationship between the LCD and the base are restricted by the return springs. When the release button is operated, the angle of elevation of the LCD is adjustable.
