PIVOT STRUCTURE AND AN ELECTRONIC DEVICE HAVING THE PIVOT STRUCTURE
A pivot structure includes a first driven device, a middle driven device, a second driven device, a driving axis, a first restriction device, a middle restriction device, and a second restriction device. The first restriction device includes a first circumferential portion and a second circumferential portion, the middle restriction device includes a first recess and an abutting portion, and the second restriction device includes a second recess and an outer edge portion. When the first circumferential portion of the first restriction device abuts the first recess of the middle restriction device, the abutting portion of the middle restriction device abuts the outer edge portion of the second restriction device. When the second circumferential portion of the first restriction device abuts the first recess of the middle restriction device, the abutting portion of the middle restriction device abuts the second recess of the second restriction device.
