    Abstract: The present invention discloses a sheath type rotating axle structure with automatic locking mechanism, comprising a sheath device, a retainer, a pivotal axle, a locking fastener, a locking rotator, a resilient body, and a screw nut. The first axle segment of the pivotal axle is pivoted to the sheath of the sheath device to realize the function of “easy opening and firm closing,” and the sheath device is disposed with a retainer on one end to achieve the “anti-shaking” function. The second axle segment of the pivotal axle is pivoted to the through hole of the retainer and embeddingly inserted into a locking fastener and a locking rotator. The locking fastener is disposed with a pin to be securingly fixed with a pin hole formed on the retainer, and a screw nut is used to securingly fix a plurality of resilient discs or a spring. When the pivotal axle is rotated to drive the locking fastener departing from the locked position, the resilient discs (or spring) are compressed by the locking rotator.
