The invention discloses a sprayer component of 3D printing equipment, the 3D printing equipment and a nozzle position adjusting method of the sprayer component. The sprayer component comprises a sprayer structure and a mounting structure. The sprayer structure is mounted on the mounting structure, and can rotate relative to the mounting structure by taking a center axis as the center so as to adjust the position of a nozzle of the sprayer structure. The 3D printing equipment comprises the sprayer component. The sprayer structure of the sprayer component is arranged rotatably. By the nozzle position adjusting method, the position of the nozzle in the sprayer component can be adjusted conveniently. The structure is simple, and simplicity and convenience in operation are achieved.
