Abstract:
1. A dual-shaft pivot device, comprising: a resilient guide assembly, the resilient guide assembly comprising at least one resilient guide member which is a resilient guide plate, each end of the resilient guide member having a hollow accommodation portion, each of the accommodation portions communicating with a connecting groove which extends toward a middle section of the resilient guide member, one end of an inner wall of at least one of the accommodation portions, displaced from the connecting groove, and having an end protrusion; and two parallel first and second pivotal shafts, at least one of the first and second pivotal shafts having middle portions which are inserted in the respective accommodation portions of the resilient guide member, the middle portions having middle flat surfaces able to get contact with the end portions for the middle portions to push the end protrusions during turning to bring resilient deformation of the accommodation portions so that when the first and second pivotal shafts inserted in the accommodation portions are turned to a predetermined angle, the accommodation portions resiliently press the middle flat surfaces for at least one of the first and second pivotal shafts to generate a driving force toward the end protrusions.
