One end of the top cover is pivotally connected to the first body and is adapted to expand at a first included angle relative to the first body. The second body is pivotally connected to the other end of the top cover and is adapted to expand a second included angle relative to the top cover. The bracket has a first end and an opposite second end, and the first end is pivotally connected to the back of the second body. The first magnetic component is disposed on the second end. The second magnetic component is disposed on the top cover and corresponds to the first magnetic component. When the electronic device is in a viewing mode, the top cover is deployed on the first body and forms a first included angle, and the second body is deployed on the top cover and forms a second included angle. The first magnetic component and the second magnetic component magnetically attract each other to drive the The bracket is deployed on the second body.
