PCB buffer protection structure convenient to assemble

The utility model relates to a PCB (printed circuit board) buffer protection structure convenient to assemble, which belongs to the technical field of PCBs, and comprises a mounting piece with an opening at the upper part, buffer sleeves capable of moving up and down are arranged at the two ends of the inner side of the mounting piece, and the buffer sleeves are connected with the mounting piece. The bottom of each buffering sleeve is fixedly connected with a vertical buffering spring fixedly connected with the bottom of the installation part, the sides, close to each other, of the two buffering sleeves are movably provided with buffering assemblies in a buffering mode, and a PCB is installed between the two buffering assemblies. The buffer sleeve can be pulled out of the inner side of the installation part only through the spring at the bottom of the buffer sleeve, so that the buffer sleeve can move left and right after being pulled out, the installation space is enlarged, the PCB can be conveniently install
