[0021] In a specific embodiment, two rubber strips 15 are slidably connected to the bottom of the dust hopper 6. The length of the rubber strips 15 is greater than the width of the dust hopper 6. The two rubber strips 15 are arranged in parallel, and the dust hopper 6 is arranged in contact with the workpiece 3 through the two rubber strips 15.
