the sliding mechanism 2 includes two sliding units, denoted as a first sliding unit and a second sliding unit; the first sliding unit is slidably connected to the horizontal portion 112 of the first bracket, and the second sliding unit is slidably connected to the horizontal portion 122 of the second bracket; the connecting piece 23 is arranged between the first sliding unit and the second sliding unit, and the first sliding unit and the second sliding unit can rotate around the connecting piece 23, so that the included angle between the horizontal part 112 of the first bracket and the horizontal part 122 of the second bracket can be changed randomly when an earthquake occurs, and the first bracket 11 and the second bracket 12 can be displaced relatively in any horizontal direction. Preferably, the first bracket 11 and the second bracket 12 are both steel frames.
