The nylon roller is light in weight, convenient to install, good in wear resistance and long in service life, and the silicon rod flaw-piece 8 is not easy to damage. By using the slider 3, the clamping arm 21 is in contact with the silicon rod edge skin 8 through the slider 3, and the slider 3 changes the sliding friction between the clamping arm 21 and the silicon rod edge skin 8 into rolling friction, which helps to reduce the possibility that the clamping arm 21 damages the silicon rod edge skin 8.
