In order to solve the problems that a traditional high-voltage electric wire lap joint foreign matter removal mode is low in safety, high in maintenance cost and low in cleaning efficiency, and the existing CO2 laser ablation simple device is not suitable for removal of long-distance or relatively small foreign matter; the invention provides a three-path coaxial transmission type CO2 laser ablation device. A CO2 laser beam expanding and focusing system, a visible light camera and a laser ranging system are realized in a three-path coaxial mode through a coaxial spectroscope group; the CO2 laser beam expanding and focusing system is based on an off-axis RC mirror group, central shielding is avoided, the quality is light and the use requirement of a large caliber can be met; the optical axisof the visible light camera is kept coaxial with the optical axis of the CO2 laser beam expanding and focusing system, so that the best ablation effect can be ensured; the optical axis of the rangingsystem is kept coaxial wi
