An electronic device comprises a base, a system module, and at least one axle pivot structure. The axle pivot structure connects the base and the system module, and the axle pivot structure comprises an axle shaft, a first pivotal connection portion, and a second pivotal connection portion. The axle shaft comprises a first end portion and a second end portion. The first pivotal connection portion is pivotally disposed to the first end portion of the axle shaft and the center of the lateral side of the base. The second pivotal connection portion is pivotally disposed on the second end portion of the axle shaft and one lateral side of the system module. Besides, the axle shaft is rotated with respect to the base, and the system module is rotated with respect to the axle shaft, so the different disposed location and disposed angle of the system module can be formed.
