The invention relates to the technical field of drop tests, in particular to a quick release device for a drop test of a small engine. Comprising a clamping mechanism, a rotating shaft, a base, an adapter, a thin air cylinder, a protection device, an adjusting nut, a tension spring, a thrust ball bearing, a nut, a wedge-shaped block piston rod and a locking nut, the clamping mechanism is fixedly connected with the base through the rotating shaft, and the thin air cylinder is fixedly connected with the upper end face of the base through the adapter; the protection device is fixed to the adapter through an adjusting nut, a piston of the thin air cylinder is connected with a wedge-shaped block piston rod, the clamping mechanism is fixed to the adapter through thrust ball bearings on the two sides, a tension spring is connected to the middle of the driving end of the clamping mechanism, and the clamping mechanism is assisted to be rapidly opened. In an engine drop safety test, safe and reliable lifting of the small engine is realized, the thin steel wire for binding the small engine is quickly released after the gas path valve is reversed, and safe and reliable proceeding of the small engine drop test is guaranteed.
