A self-retracting rotary office eraser brush

Abstract

The invention discloses a self-closing rotary office wiping brush, which comprises a suction positioning cylinder, wherein a suction magnet is fixedly mounted to the bottom end of the suction positioning cylinder; an electric small motor is fixedly mounted to the middle of the inner surface of the side wall of the suction positioning cylinder; a first rotary positioning plate is integrally connected and fixed to the top end of the suction positioning cylinder; a rotary shaft is fixedly mounted to the center of the first rotary positioning plate; the bottom end of the rotary shaft is connectedwith the power output end of the electric small motor; and meanwhile, a folding seat, a gear linkage mechanism and a limiting block seat are arranged at the top of the rotary shaft in a sleeved mannerin sequence, wherein a folding mechanism is mounted on the folding seat, and plate brushes are fixedly mounted on the folding mechanism. The wiping brush of the invention is directly sucked and fixedon a writing board, can rotate and wipe while extending outwards, can improve wiping efficiency, and does not need manual operation.

Description

Technical field [0001] The invention belongs to the field of office equipment and relates to a self-retracting rotary office eraser brush. Background technique [0002] Sometimes it is necessary to write on the writing board for presentation during the meeting. Nowadays, the writing board is basically magnetic. You can directly fix the notices, manuscripts and other paper documents on the writing board with magnets, but the existing wipe brushes are still Wiping is done manually.
