This structure can make the hair surface produced by rolling the rolling teeth 301 on the concrete smooth, regular, and with consistent depth through the rolling teeth 301 arranged at equal intervals. The hair roller brush body 1 is provided with a U-shaped fixing seat 5 that is clamped relative to the rolling cylinder 3, and a handle rod 4 is fixed on the U-shaped fixing seat 5 by welding. This structure allows the hair roller brush body 1 to control the rolling cylinder 3 to move through the handle rod 4 to achieve surface layer The roughening treatment of concrete, and the U-shaped fixing seat 5 and the positioning shaft 2 are penetrated and fastened, the length of the positioning shaft 2 is greater than the length of the U-shaped fixing seat 5, and the two ends of the positioning shaft 2 are symmetrically opened with connecting holes 201. This structure makes the two ends of the positioning shaft 2 exceed the U-shaped fixing seat 5. At the same time, the positioning shaft 2 and the U-shaped fixing seat 5 are fastened, so that the positioning shaft 2 and the U-shaped fixing seat 5 form a relatively stable structure, allowing the rolling cylinder 3 to rotate under the positioning of the positioning shaft 2 and the U-shaped fixing seat 5, so that the rolling cylinder 3 rolls the concrete to form a rough surface on the concrete surface, the connecting hole 201 and the positioning shaft 2 are coaxial structures, and the pin structure passing through the roller brush positioning frame 6 is rotatably connected to the positioning shaft 2 at the connecting hole 201. This structure enables the roller brush positioning frame 6 to rotate with the center of the positioning shaft 2 In order to rotate the point, the relative position between the positioning shaft 2 and the positioning arc plate 601 is adjusted. A roller brush positioning frame 6 is provided at both ends of the positioning shaft 2, and a positioning arc plate 601 is welded and fixed on the roller brush positioning frame 6. The roller brush positioning frame 6 is an L-shaped plate structure, and the straight-line distance from the bottom of the roller brush positioning frame 6 to the point of the positioning arc plate 601 and the axis of the positioning shaft 2 is equal. This structure enables the roller brush positioning frame 6 to relatively connect the positioning shaft 2 and the positioning arc plate 601 through the L-shaped structure. At the same time, when the roller brush positioning frame 6 rotates relative to the positioning shaft 2, the axis of the positioning arc plate 601 and the axis of the positioning shaft 2 are always in the same plane, avoiding the change of the angle of the positioning shaft 2 and affecting the position of the rolling cylinder 3, ensuring the consistency of the rolling force of the rolling cylinder 3, thereby ensuring the pulling In order to ensure the consistency of hair depth and avoid roughness and unevenness, the positioning arc plate 601 is a semicircular structure, and the opening of the positioning arc plate 601 faces downward. This structure can realize the convenient connection between the hair pressing roller brush body 1 and the roller brush guide rod 7 through the semicircular structure of the positioning arc plate 601, so that the hair pressing roller brush body 1 can be pulled under the positioning of the roller brush guide rod 7. The positioning arc plate 601 is equipped with a rolling ball 602 at intervals, and the rolling ball 602 is in contact with the roller brush guide rod 7.
