A pivot mechanism and an electronic device applying the same are provided. The pivot mechanism includes a pedestal having a bore passing through the pedestal; a shaft inserted into the bore and having at least two leaning surfaces in parallel to an extending direction of the shaft; two bushes coupled to the shaft and fixed in the bore; and a reed set disposed in the bore and arranged between the two bushes. The reed set includes at least one reed, wherein each reed is wedged in the bore and has a hole through which the shaft penetrates. At least one position limiting portion is formed in the periphery of the hole for orienting the shaft. The position limitation portion further extends inwardly to form a slot, by which a cantilever is formed between the slot and the axis hole to lean against the shaft.
