The tool adjusting component includes a three-axis adjusting frame, a first turntable at the bottom of the three-axis adjusting frame, and a heating knife holder arranged on the three-axis adjusting frame; during use, the distance between the heating knife and the tire tread is adjusted by using the first guide rail, the up and down position of the heating knife and the tire tread is adjusted by using the second guide rail, and the left and right position of the heating knife and the tire tread is adjusted by using the third guide rail. Furthermore, the three-axis adjusting frame combines the first turntable and the second turntable to precisely adjust the position of the heating knife. The function of the first turntable is to adjust the position of the engraving knife tip, which can adjust the position of the engraving knife at the flat part and the curved part of the tread. The second turntable can adjust the angle of the engraving knife at the tread. By using the electric heating method, the temperature of the heating knife is increased, and the tire is driven to rotate, so that the engraving knife performs semi-automatic engraving on the tire surface.

[0004] However, most of the existing positioning toolings require manual handling of the tire, which is time-consuming and laborious and is very likely to injure workers. Moreover, the existing positioning toolings are difficult to be applicable to tires of different sizes, and the scope of use is limited. Content of the Utility Model
