But it is patented worldwide and is very expensive.Rotating cantilever and improved cantilever are not widely used because of their complicated structures and its high request for moving rail or sliding shoe. Comparison is made among the three types of skidding of the traditional cantilever base-pawl movement, pin roll movement and gear-rack movement.Among them, pin roll movement is adopted wi
