[0002] Automobiles are the most important means of transportation for people to travel now and have entered millions of families. Due to the large number of internal parts in automobiles, the automobile processing industry is growing stronger; various steel pipes are required in automobile parts. During the processing of steel pipes, they need to be cut into different lengths by laser cutting and then undergo subsequent processing.

[0003] The shapes of steel pipes are also different. When the existing steel pipes are undergoing laser cutting, the fixtures used can only press and fix the steel pipes by pressing down. Since the overall structural strength of the steel pipes is not particularly high, in order to avoid deformation of the steel pipes, a large pressing force cannot be used during pressing and fixing. Therefore, the positioning process of the steel pipes during laser cutting is not stable enough, and the situation of left - right sliding is likely to occur, resulting in the displacement of the steel pipes and thus affecting the laser cutting effect. Therefore, it is necessary to further improve the structure of the existing laser cutting fixtures. Content of the Utility Model
