The utility model relates to a scanner is with preventing that it destatics brush to fall a mao anti -scratch, including brush yoke and the first unit of brush, it is in including resilient seating and the one end embedding that sets up in the brush yoke to brush first unit a plurality of brush hairs in the resilient seating the brush hair other end is connected with globular brush head brush hair embedding resilient seating one end is connected with the lug. The utility model relates to a rationally, the brush hair built -in end sets up the lug structure, effectively prevents a mao phenomenon that appears in the use to, the easy problem of being worn into edges and corners fish tail paper of brush is solved, a carbon fiber brush hair body structure that adopts, with low costs, effective static elimination to the design of the globular brush of brush hair other end head.
