The utility model relates to an used remote control spray gun of on-line treatment wire foreign matter, including line tackle, spray gun, wireless remote controller and balancing unit, said line tackle links to each other with balancing unit through insulating rope with transmission pulley, transmission pulley including walking the line pulley, and the one side at balancing unit is fixed to the spray gun. Will through the line tackle the utility model discloses adjust to near floater, through adjusting insulating rope near perhaps keeping away from the wire. The thermal cutting clearance conductor drop down foreign matter and the floater on the road of the high temperature spray gun through taking fuel certainly. Owing to be provided with the balance pipe, the balance pipe can make the utility model discloses can not rotate, remain same direction throughout. The utility model discloses changed traditional operating method, the will not improves maneuverability's scope greatly and improves the work accomplishment ratio because thickness, width, the winding degree affect using effect of floater just can not receive wire model, arrangement's restriction, has strengthened the commonality, is a live working tool that the commonality is extremely strong.
