The three anti-slip pads 31 can not only adapt to the long plate-shaped processing material main body 2, but also adapt to the circular or polygonal processing material main body 2, which is more practical. By rotating the rocker 41 clockwise, the bidirectional threaded rod 42 is driven to rotate clockwise. The bidirectional threaded rod 42 is set to extend to both sides with the middle as the boundary line, thereby driving the two threaded blocks 43 to move toward the middle, and then driving the two moving blocks 45 to move toward the middle, so that the two limit plates 46 move toward the middle. A limit plate 46 is set at one end. There is a bent plate 47, and the bent plate 47 is set in an arc-shaped plate shape, so that the movement of the limit plate 46 is more stable. When it contacts the processing material body 2, it will move forward, so that the sliding rod 49 moves along the sliding sleeve 48, and the spring 40 is compressed. Under the action of the spring 40, the limit plate 46 is more closely fitted to the processing material body 2.
