Description

Technical Field

[0001] The invention relates to the field of beauty and hairdressing, and in particular to a haircutting comb capable of controlling the trimming length. Background Art

[0002] At present, the haircutting method mainly relies on the barber to determine the trimming length of the hair by the degree of inclination of the comb. Although this method is flexible, it also has significant technical limitations and requires extremely high experience and hand-eye coordination of the barber. Different inclination angles will directly affect the accuracy and uniformity of haircutting. A little carelessness may lead to inconsistent hair lengths, which in turn affects the overall effect. Since the degree of inclination of the comb cannot be accurately quantified and recorded, errors are inevitable during the operation, especially when dealing with complex hairstyles or multi-layered effects. The high dependence of this technology on human experience makes the standardization and repeatability of the operation poor. The techniques of different barbers may lead to significant differences in the effect, which is difficult to meet the user's demand for uniform quality. For users who trim by themselves, the technical difficulty is more prominent, especially it is almost impossible to accurately grasp the inclination angle of the comb, and the blind spot in the back of the head area further exacerbates the complexity and uncertainty of the operation. It is difficult for users to accurately adjust the angle of the comb and scissors under a limited field of view, which not only increases the time cost and energy consumption, but also the final effect is difficult to be satisfactory. Therefore, there are still urgent problems to be solved in the existing haircutting technology in terms of efficiency, accuracy and user experience. Summary of the invention
