It is usually composed of a frame, a motor, a drive arm, a roller bearing, a support rod, a steering wheel, and a splint. The motor drives the bearing seat to rotate horizontally, and the middle drive arm is used as a connection. Through the assembled multiple motors, the angle adjustment operation of the industrial fan is completed, thereby completing the overall angle adjustment operation.
