The key points of its technical solution are: the cross-section of the guide rail body is "T"-shaped, the vertical part of the guide rail body and the guide rail seat are perpendicular to each other, and the cross-section formed with the guide rail seat is a complete "I" shape. Heat dissipation holes are opened on the upper surface of the guide rail body, and the cross-section of the guide rail forms an "I"-shaped cavity. The invention adopts the "I"-shaped structure to make the combination of the guide shoe and the guide rail more stable, and the interior of the guide rail is hollow. Heat dissipation holes are also opened on the upper surface of the guide rail, which reduces deformation caused by frictional heat, reduces safety hazards, and saves materials.
