[0030] The hair cutting roller brush comprises a blade and a rotating cylinder 3-1, the blade is arranged in the rotating cylinder 3-1, and the dynamic blade 3-2 is driven to reciprocate and cut hair synchronously by a driving structure while the rotating cylinder 3-1 rotates, the driving structure comprises a reciprocating push rod, the rotating cylinder 3-1 is provided with a blade push rod 3-6, the blade push rod 3-6 rotates together with the rotating cylinder 3-1, the blade push rod 3-6 is connected with an elastic element 14, one end of the blade push rod 3-6 is connected with an adjacent end of the reciprocating push rod, the reciprocating push rod is used for driving the blade push rod 3-6 to move in one direction, and the elastic element 14 is used for enabling the blade push rod 3-6 to return in the opposite direction when the reciprocating push rod is retracted, and a concave-convex matching structure capable of rotating relatively is arranged between the one end and the adjacent end. In this way, the concave-convex matching structure capable of rotating relatively can realize reciprocating movement and relative rotation, the structure is simplified, and the cost is greatly reduced.

[0031] The concave-convex matching structure comprises a concave surface 15 and a spherical convex surface, and the concave surface 15 and the spherical convex surface are concave-convex matched. In this way, the concave-convex matching structure can realize adaptive concave-convex matching, is more conducive to movement, and has enhanced tolerance to small deformation or precision of parts, so that the blade push rod 3-6 is made of plastic material instead of metal material, thereby greatly reducing the cost.

[0032] The one end is provided with a ball 16, and the adjacent end is provided with a concave surface 15. In this way, the concave-convex matching is better, and movement is more conducive.

[0033] The ball 16 is movably connected with the one end. In this way, since the one end of the blade push rod 3-6 relatively to the adjacent end has both abutting driving and rotating, if the ball 16 is movable, the movement friction between the ball 16 and the concave surface 15 can be significantly reduced, the reliability is significantly improved, and the service life is prolonged. In addition, the adaptive concave-convex matching is also facilitated.
