Short summary
Hidden-keyhole padlocks are reconfigurable mechanisms and a category of ancient Chinese locks. This work presents a useful procedure to indicate and analyze the topology variabilities of hidden-keyhole padlocks. The variable chains of hidden-keyhole padlocks are presented by using the representation of kinematic pairs, from which all topology variabilities of padlocks in the operation are derived. Four main types of hidden-keyhole padlocks are provided as examples to illustrate the procedure.
