Claim Text:
1. An engaging module, suitable for a first object and a second object, the first object and the second object being adapted to be combined or separated along a first axial direction, the engaging module comprising: an engaging component, movably disposed on the first object, wherein when the first object and the second object are combined, the engaging component is adapted to move to a first position along a plane to be engaged with the second object and adapted to move to a second position along the plane to separate from the second object, wherein the first axial direction is not parallel to the plane; an elastic component, connected between the engaging component and the first object, wherein the engaging component is positioned at the first position through an elastic force of the elastic component; at least one electromagnet, disposed on the first object, wherein the engaging component is adapted to resist the elastic force of the elastic component to be positioned at the second position through a magnetic force generated by the electromagnet; a first electrical connection portion; and a second electrical connection portion, wherein the first electrical connection portion is disposed on the first object and electrically connected with the electromagnet, the second electrical connection portion is disposed on the second object and electrically connected with a power supply, when the first object and the second object are combined, the first electrical connection portion contacts the second electrical connection portion, such that the electromagnet is adapted to receive electricity from the power supply, and when the first object is separated from the second object, the first electrical connection portion does not contact the second electrical connection portion.
