[0049] The dust removal roller 45 is moved to dock the rear end of the slip ring column 441 with the front end of the block tube 442. When the hemisphere contacts the bottom end of the sliding block 4431, the sliding block 4431 rises and passes through the hemisphere to move onto the annular groove. When the annular groove contacts the bottom end of the sliding block 4431, the sliding block 4431 enters the annular groove through the elastic force of the spring to achieve engagement. When it is necessary to release the installation, the block tube 442 is moved forward to allow the sliding block 4431 to rise and pass through the slip ring 4411 to move to the front side of the slip ring 4411, and then the block tube 442 is moved backward again. The sliding block 4431 first drives the slip ring 4411 to move backward, and the rear end of the slip ring 4411 slides with the recess, and then the bottom end of the sliding block 4431 rises through the arc surface of the slip ring 4411 and passes through the hemisphere at the rear end of the slip ring column 441 to separate from the slip ring column 441, thereby achieving quick installation and disassembly.
