A second movable groove 77 is formed in the inner wall of the sixth connecting section 7, a sixth connecting block 731 matched with the second movable groove 77 is arranged on the side wall of the baffle plate 73, and a plurality of balls are arranged on the inner wall of the second movable groove 77; the ball bearings are respectively arranged on the top inner wall and the bottom inner wall of the second movable groove; the sixth connecting block is matched with the second movable groove to fix the baffle plate in the sixth connecting section, so that the baffle plate is prevented from falling out of the sixth connecting section; the friction force between the second movable groove and the sixth connecting block is reduced under the action of the balls, the flexible shaft is convenient to drive the baffle to rotate, and therefore the drill bit rotates, and a certain labor-saving effect is achieved.

Further, the number of the second connecting section and the fifth connecting section can be increased according to the required length, so that the length of the dredger is increased, and the dredger can be used for a longer type of pipeline.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
