A mechanism for adjusting a rotary angle of an LCD includes: a lower base with a sector rack and arcuate sliding grooves disposed at the top surface thereof; an upper base disposed with an LCD at an upper portion thereof, the bottom surface of the upper base being disposed with sliding posts for movably engaging with the arcuate sliding grooves; and a positioning mechanism including a positioning spring and a positioning push button. The positioning spring constantly urges the positioning push button to mate with one of the protruding teeth of the rack, thereby positioning the rotary angle of the upper base and the LCD. When the positioning push button is inwardly pushed, the positioning push button is disengaged from the protruding tooth thereby enabling the LCD to rotate right and left. The adjusting mechanism further includes an inhibiting mechanism for restricting the rotating scope of the LCD.
