The intelligent teaching table for a smart classroom as claimed in claim 1, wherein: the working principle is as follows: when the computer is not needed to be used, the computer descends into the desk body (1) along with the supporting block (6), the stop block (11) is driven to move into the groove (1-1), and the stop block (11) and the top plate of the desk body (1) are integrated, so that the available area on the desktop of the desk body (1) is increased, dust is blocked, and dust accumulation on the computer is avoided; on the contrary, when the computer needs to be used, the first air cylinder (3) drives the connecting frame (7) to move downwards, so that the connecting seat (12) drives the stop block (11) to move downwards, meanwhile, the driving motor (10-1) is started to drive the external threaded pipe (10-2) to rotate, and the internal threaded pipe (10-3) is driven to move through the threads, so that the connecting support block (8) is driven to drive the stop block (11) to move forwards and is arranged above the connecting seat (12), and the stop block (11) is far away from the open groove (1-1); the two-way screw rod (9-2) is rotated by starting the rotating motor (9-1), because the threads on the two-way screw rod (9-2) are arranged in a front-back opposite way, when the two-way screw rod (9-2) rotates, the rotating directions of the threads arranged in opposite ways on the two-way screw rod are opposite, so that the moving directions of the two sliding blocks (9-3) are opposite, the sliding blocks (9-3) move to drive the lower ends of the rotating support rods (9-6) to move, the upper ends of the two rotating support rods (9-6) perform reverse rotating movement through the rotating joint points at the intersection and guide through the sliding fit of the sliding rods (9-11) and the sliding grooves (9-8-2), so that the connecting blocks (9-9) are driven to perform high movement, and the supporting blocks (6) perform high movement, thereby driving the computer to move, and pushing upwards through the second cylinder (4), so that the supporting seat (5) is pushed upwards, thereby driving the computer to move upwards until the upper surface of the supporting block (6) is flush with the upper surface of the desk body (1), and further operating the computer.
