The other end of the connecting pipe 75 is connected to the inside of the collection box 76. A filter element 78 is installed in the collection box 76. The two sides of the collection box 76 are connected to the fan 77.

[0051] When the valve body 61 is being polished, the fan 77 is activated, and the waste generated by the polishing is sucked into the filter element 78 in the collection box 76 through the annular tube 72 through the L-shaped tube 73, the sleeve 74 and the connecting tube 75, thereby realizing dust-free polishing and preventing waste from polluting the working environment. At the same time, when the fastening module 6 is adjusted, the L-shaped tube 73 slides in the sleeve 74, thereby ensuring that the waste collection module 7 can extract the waste normally.
