The invention relates to a novel multifunction computer display. By adjusting the rack to drive the planetary gear train to rotate, the planetary gear is driven by the power transmission of the worm gear and the screw threaded with the third worm to complete the feeding in the left and right directions, the two sets of screws are identical to the cylinders, a four-bar linkage mechanism composed ofa display and a connecting rod adjusts the upper and lower angles of the display, you can also move the drive handle up and down selectively, whether the cylinder is adjusted reciprocally or not is realized, and a clever reversing device is introduced at the same time, while dissipating heat, selective angular adjustment is performed in the anterior and posterior directions, when the angle adjustment is carried out before and after, because the third worm is symmetrically arranged, the upper and lower angle adjustments are not affected. The invention utilizes the power output of heat dissipation to carry out angle adjustment, reasonably utilizes resources, is simple and convenient to operate, has ideal angle adjustment effect, and can reduce the incidence probability of cervical spondylosis, and has ingenious structure and strong practicability.
