The invention relates to a release locking mechanism for an azimuth axle of an azimuth tracking cloud deck system. The release locking mechanism comprises a worm assembly, two worm bearings, an eccentric sleeve, two slide bearings, a wrench assembly, a worm gear and a hand wheel assembly. Two ends of the eccentric sleeve are respectively installed on a to-be-installed installation seat in a rotating manner through the slide bearings. The wrench assembly is fixed on one end of the eccentric sleeve. The worm assembly is installed in the eccentric sleeve in a rotating manner, and the axis of the worm assembly is deviated from the rotary axis of the eccentric sleeve. The worm assembly comprises a mandrel and a worm, and the worm gear and the worm can be engaged with or separated from each other along with the rotation of the eccentric sleeve; the hand wheel assembly is fixed on a first end of the mandrel. The worm gear is installed on the azimuth axle in a box body. When a wrench is pulled, the worm is engaged with the worm gear, and the fine adjustment is realized by shaking the hand wheel assembly; the wrench is pulled in the opposite direction, so that the worm is separated from the worm gear, and high-speed rotation is realized. According to the release locking mechanism, the structure is simple, the system size and the system weight can be effectively reduced, the operation is simple and convenient, and the working efficiency of an operator can be remarkably improved.
