Circuit board with compression-resistant protection function

The utility model discloses a circuit board with a compression-resistant protection function, which comprises a circuit board body, a connecting substrate, a compression-resistant damping frame and fixing supports, the lower surface of the circuit board body is fixedly connected with the connecting substrate, the fixing supports are embedded into the two sides of the lower surface of the connecting substrate, and the interior of each fixing support is of a hollow structure. According to the utility model, through the arrangement of the compression-resistant damping frame, when the circuit board body is extruded in the transportation process, the circuit board body and the fixed support can extrude the damping stretching rod towards the lower end, and when the damping stretching rod is extruded, the damping frame sliding block connected with the lower end of the damping stretching rod can slide in the compression-resistant damping frame; the movable protection sliding blocks connected with the upper ends of th
