Oscillating assembly and fan

Abstract

The embodiments provides an oscillating assembly and a fan. The oscillating assembly is used for the fan, and the fan comprises a fan head and an upright tube. The oscillating assembly is configured to drive the fan head to rotate. The oscillating assembly comprises: a driving assembly mounted in the upright tube and comprising an output shaft; a mounting seat mounted in the upright tube, the mounting seat being provided with a mounting hole; a shaft sleeve mounted in the mounting hole; a rotating shaft rotatably mounted in the mounting hole through the shaft sleeve, one end of the rotating shaft being connected to the output shaft, and the other end of the rotating shaft being configured to connect to the fan head. The solution realizes the rotatable mounting of the rotating shaft in the mounting seat through the shaft sleeve, and can reduce product cost.
