The utility model discloses an anti-disengagement fine-adjustable quick-detachable structure, which comprises a shaft lever, a spanner rod and a fine-adjustable unit; wherein the shaft lever has a small-diameter portion and a large-diameter portion, an anti-disengagement end face is formed at a junction between the small-diameter portion and the large-diameter portion, and the spanner rod is screwed to one end of the shaft lever; and the fine-adjustable unit has an inner sleeve and an outer sleeve, the inner sleeve has an axially penetrating through hole and a fine-adjustable external thread, the outer sleeve is hollow annular, a small-diameter hole and a large-diameter hole communicated with the small-diameter hole are arranged on an inner circumferential surface of the outer sleeve, a fine-adjustable internal thread is arranged on a hole wall of the small-diameter hole, the fine-adjustable internal thread of the outer sleeve is screwed onto the fine-adjustable external thread of the inner sleeve such that the outer sleeve rotates under an external force to move in a reciprocating manner along an axial direction of the inner sleeve, the through hole of the inner sleeve allows the shaft lever to pass through, the inner diameter of the large-diameter hole is greater than the outer diameter of the large-diameter portion of the shaft lever, and the inner diameter of the small-diameter hole is smaller than the outer diameter of the large-diameter portion of the shaft lever, thereby achieving the effect of preventing component disengagement.
