Needle tip inclination detection device and welding tool of printing and dyeing spray needle

The invention provides a needle tip inclination detection device and a welding tool of a printing and dyeing spray needle, and belongs to the technical field of detection, the detection device is used for detecting the needle tip inclination of a needle tube, the detection device comprises a detection block, a detection groove, a positioning channel and a detection surface, the detection surface is located in the extension direction of the positioning channel, the included angle between the detection surface and the center line of the positioning channel forms a detection angle, and the angle of the detection angle corresponds to the inclination of the needle tip. The detection block is provided with a standard detection angle, and the detection equipment can quickly judge the qualification of the inclination of the needle tip by comparing the included angle between the tangent plane and the detection plane, does not need tedious procedures such as focusing, is high in detection efficiency and simple to opera
