When all the plug-in frames 7 are disengaged from the limiting slots, the dust box 3 is unlocked, thereby conveniently and quickly locking and unlocking can be performed, and no external tools are required. The staff can lock and unlock by hand, and then the staff rotates the rotating frame 14, and the rotating frame 14 rotates to drive the locking block 15 to slide in the internal slot of the limiting slide slot 16, and then pulls the plug-in frame 12 to extract it. When it is extracted, the locking block 15 slides inside the limiting slide slot 16. When the plug-in frame 12 is extracted, the staff pulls the dust box 3 through the handle 17 to extract the dust box 3 and collect the dust.
