The invention discloses an electrical cabinet protection base, and relates to the technical field of electronic products. The electrical cabinet protection base comprises a base. Bottom grooves are fixedly connected on the two sides of the top part of the base. A flexible block is slidably connected on the right side of the internal part of each bottom groove. A first spring is fixedly connected between the left side of the flexible block and the left side of the internal wall of each bottom groove. A support rod is rotatably connected on the surface of the flexible block. A lead screw grooveis rotatably connected on one end, which is away from the flexible block, of the support rod. A lead screw is rotatably connected in the lead screw groove. According to the electrical cabinet protection base, the bottom grooves are fixedly connected on the two sides of the top part of the base, the flexible block is slidably connected on the right side of the internal part of each bottom groove, the support rod is rotatably connected on the surface of the flexible block, the lead screw groove is rotatably connected on one end, which is away from the flexible block, of the support rod, the leadscrew is rotatably connected in the lead screw groove, vertical rods are rotatably connected on the two sides of the surface of the lead screw, and clamping devices are fixedly connected on the opposite sides of the two vertical rods to clamp and fix the electrical cabinet so that the stability is high and the use effect is great.
