Abstract: A brush module for a rotary table includes: a housing, a brush unit, a first pushing unit and a second pushing unit, the brush unit includes a brush disposed in the housing, a conductive wire electrically connected to the brush, and a pushing force for pushing the brush towards the opening of the housing. The first and second pushing units oppositely provided on the housing provide the brush a first and a second pushing forces in opposite directions to resist the lateral thrust generated by friction between the brush and the rotary disk of the rotary table, thereby greatly reducing the vibration, shaking, slipping, line contact and other conditions of the brush caused by high-speed rotation of the rotary disk, avoiding damaging the peripheral surface of the rotary disk, and maintaining good electrical contact between the brush and the rotary disk.
