The invention discloses a stepless variable nozzle with controllable outlet aperture. The stepless variable nozzle comprises a nozzle body, a nozzle cap, a support, a spring, an ejector rod, a valve core, a servo motor and a cam, wherein the nozzle body is connected with the nozzle cap; the valve core is arranged in the nozzle body; the support is arranged on the nozzle cap; the servo motor is arranged on the support; the cam is arranged on an output shaft of the servo motor, is kept in contact with the ejector rod below the servo motor and is pre-tightened through the spring; the ejector rodsequentially penetrates through the nozzle cap and the valve core; the servo motor drives the cam to rotate so as to push the ejector rod to do linear motion; and the size of the outlet aperture of the nozzle body, that is, the size of the cross-sectional area of a through-flow, is changed through a conical head at the tail end of the ejector rod, so that the size of the flow rate or the spray amount of the nozzle is adju
