[0006] The second brush body includes a rotating arm, the end of which is rotatably connected to the side wall of the brush head body, and a transverse bristle rod is provided at the front end of the rotating arm, on which third bristles are provided; after the rotating arm is rotated, it can reach a third position at the rear and a fourth position at the front and stop rotating at the third and fourth positions, and when the rotating arm is located at the third position, the bristle rod is located above the rear of the brush head body; when the rotating arm is rotated 180° and is located at the fourth position, the bristle rod is located in front of the front end of the channel.

[0007] Furthermore, the front part of the brush head body is provided with a first positioning groove and a second positioning groove located in front of the first positioning groove; the inner wall of the sleeve body is provided with an inner sleeve positioning protrusion;

[0008] When the sleeve body is located at the first position, the positioning protrusion in the sleeve is snapped into the first positioning groove; when the sleeve body is located at the second position, the positioning protrusion in the sleeve is snapped into the second positioning groove.

[0009] Furthermore, a recessed portion is provided on the brush head body, and the first positioning groove and the second positioning groove are located in the recessed portion.

[0010] Furthermore, there are two rotating arms, which are rotatably connected to two sides of the brush head body respectively, and the bristle rod is located between the two rotating arms.

[0011] Furthermore, at least one side of the brush head body is provided with a third positioning protrusion and a fourth positioning protrusion located in front of the third positioning protrusion; the inner side of at least one rotating arm is provided with an inwardly convex positioning plate;

[0012] When the rotating arm can reach the third position after rotation, the positioning plate passes over the third positioning protrusion to stop the rotating arm from rotating; when the rotating arm is located at the fourth position after rotating 180°, the positioning plate passes over the fourth positioning protrusion to stop the rotating arm from rotating.

[0013] The beneficial effect of the utility model is that when the utility model is used, three use modes can be generated. The first mode is that the sleeve slides to the first position and the rotating arm rotates to the third position. At this time, the upper bristles, the lower bristles, and the third bristles are all located behind the front end of the channel, and all the bristles do not participate in the operation; the second mode is that the sleeve slides to the second position and the rotating arm rotates to the third position. At this time, the upper bristles and the lower bristles are located in front of the front end of the channel, and the third bristles are located behind the front end of the channel. At this time, the upper bristles and the lower bristles participate in the operation, and the third bristles do not participate in the operation; the third mode is that the sleeve slides to the first position and the rotating arm rotates to the fourth position. At this time, the upper bristles and the lower bristles are located behind the front end of the channel, and the third bristles are located in front of the front end of the channel. At this time, the upper bristles and the lower bristles do not participate in the operation, and the third bristles participate in the operation. Therefore, when using, one of the above three use modes can be selected according to different occasions, and its adaptability is stronger. BRIEF DESCRIPTION OF THE DRAWINGS
