Claim Text:
1. A rotatable roll brush comprising: a brush body part in which a plurality of comb teeth are arranged on an outer circumferential surface thereof; a handle part in which a front end part is open, an interior thereof is empty, and an elastic locking piece is installed on an inner circumferential surface thereof along the circumference of same; and a rotating body part in which a front end part couples to the brush body part, a back end part couples to the handle part so as to allow rotations, and a plurality of locking protrusions are formed on an outer circumferential surface of the back end part so that the elastic locking piece is inserted to control the rotations; the elastic locking piece being formed of an elastic material and comprising a protruding member configured to be inserted within a groove formed between two of the locking protrusions such that under normal use the protruding member abuts the locking protrusion and prevents rotation of the rotating body part; the elastic locking piece further configured so that when sufficient rotational force is applied to the rotating body part, the elastic locking piece elasticity is overcome, thereby disengaging the protruding member from the locking protrusion and allowing rotation of the rotating body part.
