Abstract

The invention discloses a cleaner brush with a freely movable connection tube, belonging to the nozzle structure of a cleaner. The invention includes a brush main body, the bottom face of which is formed with a nozzle, four sides of which are closed and the inside of which is formed with a suction space; a connection tube, which displaces in the length direction of the brush main body, is arranged on the top face of the brush main body; and the periphery of the connection tube is combined with a chute board and a telescopic component, which close the top face of the brush main body. With such design, one end of the brush main body is put under a desk or bed, the connection tube and chute board horizontally displace to the opposite end along a chute, the top face board panel at one end horizontally stretches and extends along the chute, while the top face board at the other end horizontally shrinks and folds along the chute, although the connection tube displaces in the horizontal direction, the top face board is kept in the closed state at the rectangular opening on the top face of the brush main body. Therefore, the cleaning area under the desk or bed is increased relatively, so that it becomes more inconvenient for users.
