The utility model discloses a switching type double-shaft pivot device and an electronic device using the same. The switching type double-shaft pivot device comprises a mounting assembly, a first rotating shaft, a second rotating shaft, a switching piece and a linkage push block, wherein the first rotating shaft and the second rotating shaft are mounted on the mounting assembly; the switching piece and the linkage push block are arranged between the first rotating shaft and the second rotating shaft; in the process of switching from rotation of the first rotating shaft to rotation of the second rotating shaft, the linkage push block firstly forces the second rotating shaft to rotate; on the contrary, in the process of switching from the rotation of the second rotating shaft to the rotation of the first rotating shaft, the linkage push block forces the first rotating shaft to rotate firstly. According to the utility model, the collision of the switching piece to the transmission cams of the first rotating shaf
