[0026] Connect the connecting piece to the support frame and the dial indicator 14 to the platform 1, so that the guide plate 4 is located at one end of the roller body 2, and the first plane 5 of the guide plate 4 contacts the tooth top on the tooth tip 3 at the starting position, and the second plane 6 contacts the straight side of the tooth tip 3 at the starting position, rotate the roller body 2 and move the roller body 2 horizontally. Since the second plane 6 is tightly attached to the straight side of the tooth tip 3, the first plane 5 of the guide plate 4 can be ensured to always contact the tooth top of the tooth tip 3 on different layers during the movement, so as to detect the tooth tips 3 on different layers, prevent the first plane 5 from being separated from the tooth tip 3, and improve the measurement accuracy of the tooth tip 3 of the combing roller.

[0027] According to a further optimization scheme, the distance between two tooth tips 3 located on the same horizontal line and respectively located on two adjacent circles is h, and the width of the first plane 5 and the thickness of the second plane 6 are respectively smaller than h;
