When the buffer slides to the specified position, it is tightened by screws. The installation process is relatively troublesome, and when it needs to be disassembled, the buffer needs to be slid to the end of the guide rail to be taken out. When the sliding door has been installed and used, the entire guide rail needs to be disassembled, which is very troublesome. In view of this, we have developed a new buffer structure.
