The invention discloses a quick-release helicopter tail transmission shaft assembly which comprises an integrated tail pipe beam, a tail transmission front shaft assembly and a tail transmission rearshaft assembly, the tail transmission front shaft assembly and the tail transmission rear shaft assembly are installed in the integrated tail pipe beam, the outer diameter of the integrated tail pipebeam linearly decreases in the direction away from a helicopter body, and the cross section of the integrated tail pipe beam is of an oval structure. A butt joint surface is arranged at the joint of the integrated tail pipe beam and the rear end of the fuselage, and a positioning hole is formed in the butt joint surface; the front end of the tail transmission front shaft assembly is connected witha main reduction tail output, and the rear end of the tail transmission front shaft assembly is connected with the tail transmission rear shaft assembly through a sliding fit structure and can slidewithin a certain range in the axial direction. A bearing support is installed on the tail transmission rear shaft assembly, installed on the integrated tail pipe beam and used for supporting the wholetail transmission shaft in the radial direction. The rear end of the tail transmission rear shaft assembly is connected with the tail speed reducer. The invention provides a tail transmission shaft structure capable of being quickly disassembled and reassembled, and the tail transmission shaft structure solves the problem of quick installation of a helicopter tail transmission shaft on the premise of not increasing the system complexity.
