• a first fixing body having a lower end supported by the brush body;
• and
• a second fixing body provided to extend from the first fixing body and having an upper end supporting the bristle member,
• wherein the first fixing body is provided to be inclined from a lower end of the second fixing body in a direction of the brush body,
• wherein the first coupling portion comprises:
• a first body surrounding a first side of the lower portion of the brush bristle part;
• a first inclined portion provided below the first body to be inclined in the direction of the brush body;
• and
• a first coupling body provided below the first inclined portion to be screwed to the brush body,
• wherein a first flange coupling groove is provided on an inner wall of the first body to be detachably coupled with a first side of a flange member of the brush bristle part,
• wherein the second coupling portion comprises:
• a second body surrounding a second side of the lower portion of the brush bristle part and detachably coupled to the first body;
• a second inclined portion provided below the second body to be inclined in the direction of the brush body;
• and
• a second coupling body provided below the second inclined portion to be screwed to the brush body and detachably coupled to the first coupling body,
• wherein a second flange coupling groove is provided on an inner wall of the second body to be detachably coupled with a second side of the flange member of the brush bristle part,
• wherein the first body is provided with a pair of coupling protrusions, the second body is provided with a pair of protrusion coupling grooves, and the pair of coupling protrusions is detachably coupled to the pair of protrusion coupling grooves,
• wherein the first body and the second body are coupled together to form a cylindrical shape,
• wherein the first inclined portion and the second inclined portion are coupled together to taper towards the brush body,
