ABSTRACT:
A sheath type rotating axle structure is disclosed, comprising an axle receiver disposed with a slanted corner which is further formed to have a notch therein; a sheath part disposed with a sheath end and an extending end, wherein a flute is formed at the sheath end and a rim and an annular groove are disposed between the sheath end and the extending end; and a pivotal axle pivotally connected the sheath end, disposed at its front end with a protruding ring, and embeddingly engaged with an axle hole of a fixed base at its rear end, wherein the extending end of the sheath part may be securingly mounted onto the notch of the axle receiver and the protruding ring of the pivotal axle may be abutted against the rim and the annular groove of the sheath part such that the sheath part may generate frictional torque against the pivotal axle when the axle receiver is rotated with respect to the fixed base. With the implementation of the present invention, the pivotal axle, the sheath part, and the axle receiver can be prevented from disconnecting.
