The material thereof may be a material such as bakelite having considerable hardness, a smooth surface and low friction, which can make the structure more durable and avoid damage. The material of the bearing table 32 may be similar to that of the sliding table 31. Structurally, the bearing table 32 is wrapped around the side edge of the clamping component 4.
