An umbrella handle quick-release structure includes a positioning member, a spring, and an inner sleeve. The positioning member is fixed at a lower end of an umbrella rod. The inner sleeve is secured to a mounting hole of an umbrella handle. The inner sleeve has an axial insertion hole for insertion of the umbrella rod, an axial side groove at a side wall thereof for the positioning member to slide therein along with the insertion of the umbrella rod, a transverse groove for the positioning member to slide therein along with turning of the umbrella rod, and an axial positioning groove for positioning of the positioning member after being turned. The transverse groove has a first end interconnected with a lower end of the axial side groove and a second end interconnected with the axial positioning groove. An upper end of the axial positioning groove is higher than the transverse groove. The spring is located between a bottom of the mounting hole and a lower end of the umbrella rod. The present invention is convenient, easy and safe to be disassembled, can satisfy the consumer's demand for diversification, and is advantageous for recycle and environmental protection.
