A plurality of supporting columns are installed on the lower surface of the placing frame, telescopic columns are installed on the lower surfaces of the supporting columns, threaded rods are connected to the upper surfaces of the interiors of the supporting columns, installation plates are connected to the lower surfaces of the threaded rods, driven gears are installed on the circumferential side faces of the threaded rods, rotating gears are connected to the circumferential side faces of the driven gears, and the rotating gears and the driven gears are matched in position. One end of the adjusting rod is connected with the rotating gear, and the other end of the adjusting rod is welded with the main handle. By arranging the rotating gear, the driven gear and the threaded rod, the adjusting rod is rotated, the adjusting rod drives the rotating gear to rotate, and the rotating gear drives the threaded rod to rotate through the driven gear, so that the telescopic column is driven to move up and down, and adjustment of the height of the placing frame is facilitated; and the big data host can be conveniently fixed on the placing frame and is prevented from falling off and being damaged.
