Cross target tooling device used for carrying out laser tracking and monitoring on center of pipeline

The utility model provides a cross target tooling device used for carrying out laser tracking and monitoring on the center of a pipeline. The cross target tooling device tracks the center of the pipeline through lasers so as to monitor the situation that one end of the pipeline is welded, and the other end of the pipeline is bent and deformed (that is, the position of the pipeline is changed when a welding seam of the pipeline is welded). In order to realize the aim, the cross target tooling device used for carrying out laser tracking and monitoring on the center of the pipeline has the characteristics of convenience in assembling, flexibility in adjustment, lightness and practicality in use. The cross target tooling device structurally comprises a support leg holder, a target holder, a support leg connecting rod (including an end support leg) and multiple groups of adjusting screw rods, wherein the target holder is arranged on the support leg holder, the target holder is used for installing a target, the sup
