ABSTRACT:
An angle-adjustable rotating device includes a mounting part disposed on a peripheral wall of a base member. A drive unit includes a motor and a drive shaft driven by the motor. A mounting seat is sleeved on the drive shaft, and is formed with an engaging member. A control mechanism is associated with the drive shaft in such a manner that rotation direction of the drive shaft is reversed when resistance to rotation of the drive shaft is greater than a predetermined amount of torque of the motor. A resistance providing member is mounted adjustably on the mounting part, and is engageable with the engaging member so as to provide resistance to rotation of the drive shaft.
