When the outer wall of the adjusting shaft rotates on the inner wall of the first clamping arm, it will drive the first clamping arm to rotate. The outer wall of the first clamping arm will rotate on the inner wall of the second base. When the electric push rod is started, its outer wall will slide on the inner wall of the first base and push the connecting shell of its outer wall to slide.
