A pivot apparatus adapted to connect a host and a display includes a rotary base having a first part and a second part, a connecting plate, a pivot component, a first connecting rod and a hook. The first part is embedded at the host. The second part has a rotary shaft embedded at a first edge of the connecting plate. The pivot component is pivotally connected between a rear surface of the display and a second edge of the connecting plate. The first connecting rod is slidably disposed at the connecting plate and has at least a locking hole. The hook is disposed at the rear surface and passes through the connecting plate to be slidably disposed in the locking hole. The hook is used to interfere with the first connecting rod to restrict the rotation of the display by the pivot component relative to the connecting plate.
