The invention discloses a displayer base having a protective function and relates to the related technical field of computers. The displayer base comprises a base body, wherein a base plate is fixedly connected to the top of the base, first connecting rods are movably connected to two sides of the top of the base plate, movable blocks are movably connected to the ends, away from the base plate, of the first connecting rods, second connecting rods are movably connected to the surfaces of the movable blocks, a top plate is movably connected to the ends, away from the movable blocks, of the second connecting rods, a transverse plate is fixedly connected to the top of the top plate, and a fixing rod is fixedly connected to one side of the top of the transverse plate. According to the displayer base having the protective function, the movable blocks are pushed through first springs, second springs push the top plate to achieve the damping purpose, a worm wheel is stuck through a clamping rod and accordingly clamps a lead screw to stop rotation of the lead screw, the positions of movable rods are fixed to clamp and fix a displayer, and the displayer base has the advantages of being safe, stable, not prone to offset and slippage and good in protective effect.
