Spraying pipe welding positioning tool for watering cart

The invention relates to a spraying pipe welding positioning tool for a watering cart. The problem that the precision of the welding position is poor when a connecting plate and a water inlet connector in the prior art are welded to a spraying pipe is solved. The tool comprises a base, wherein a supporting seat used for supporting and positioning the spraying pipe is arranged on the base, a nozzleseat positioning structure is arranged on the supporting seat, the nozzle seat positioning structure comprises a nozzle seat axial positioning structure for positioning and cooperating with the nozzle seat on the spraying pipe to limit the axial movement of the spraying pipe and a nozzle seat circumferential positioning structure for limiting rotation of the spraying pipe; and a connecting platepositioning structure is further arranged on the base, the connecting plate positioning structure comprises a connecting plate axial positioning structure for limiting axial movement of the connectingplate along the spraying p
